All notable changes to this project will be documented in this file.
- Changed the default base image from the
adoptopenjdk
images to theeclipse-temurin
(for Java 8 and 11) andazul/zulu-openjdk
(for Java 17) images on Docker Hub. Note that Temurin (by Adoptium) is the new name of AdoptOpenJDK. (#3491)
- Fixed
ClassCastException
when using non-String
value (for example,Provider
) forMain-Class
manifest attribute of thejar
task. (#3396) - Fixed incorrect parsing with comman escaping when providing Jib list or map property values on the command-line. (#2224)
- Downgraded Google HTTP libraries to 1.34.0 to resolve network issues. (#3415, #3058, #3409)
- If
allowInsecureRegistries=true
, HTTP requests are retried on I/O errors only after insecure failover is finalized for each server. (#3422)
- Increased robustness in registry communications by retrying HTTP requests (to the effect of retrying image pushes or pulls) on I/O exceptions with exponential backoffs. (#3351)
- Now also supports
username
andpassword
properties for theauths
section in a Docker config (~/.docker/config.json
). (Previously, only supported was a base64-encoded username and password string of theauth
property.) (#3365)
- Upgraded Google HTTP libraries to 1.39.2. (#3387)
- Fixed the bug introduced in 3.1 that constructs a wrong Java runtime classpath when two dependencies have the same artifact ID and version but different group IDs. The bug occurs only when using Java 9+ or setting
jib.container.expandClasspathDependencies
. (#3331)
- Fixed the regression introduced in 3.1.0 where a build may fail due to an error from main class inference even if
jib.container.entrypoint
is configured. (#3295)
- For Google Artifact Registry (
*-docker.pkg.dev
), Jib now tries Google Application Default Credentials last like it has been doing forgcr.io
. (#3241) - Added lazy evaluation for
jib.container.labels
using Gradle Property and Provider. (#3242)
- Jib now creates an additional layer that contains two small text files:
/app/jib-classpath-file
and/app/jib-main-class-file
. They hold, respectively, the final Java runtime classpath and the main class computed by Jib that are suitable for app execution on JVM. For example, with Java 9+, setting the container entrypoint tojava --class-path @/app/jib-classpath-file @/app/jib-main-class-file
will work to start the app. (This is basically the default entrypoint set by Jib when the entrypoint is not explicitly configured by the user.) The files are always generated whether Java 8 or 9+, or whetherjib.container.entrypoint
is explicitly configured. The files can be helpful especially when setting a custom entrypoint for a shell script that needs to get the classpath and the main class computed by Jib, or for AppCDS. (#3280) - For Java 9+ apps, the default Java runtime classpath explicitly lists all the app dependencies, preserving the dependency loading order declared by Gradle. This is done by changing the default entrypoint to use the new classpath JVM argument file (basically
java -cp @/app/jib-classpath-file
). As such,jib.container.expandClasspathDependencies
takes no effect for Java 9+. (#3280) - Timestamps of file entries in a tarball built with
jibBuildTar
are set to the epoch, making the tarball reproducible. (#3158)
- New
includes
andexcludes
options forjib.extraDirectories
. This enables copying a subset of files from the source directory using glob patterns. (#2564) - Added an option
configurationName
to specify the name of the Gradle Configuration to use. The option can be lazily configured, for example, using GradleProvider
orProperty
. (#3034)
jib {
configurationName = 'myconfig'
}
- Switched the default base images from Distroless to
adoptopenjdk:{8,11}-jre
andjetty
(for WAR). (#3124)
- Fixed an issue where some log messages used color in the "plain" console output. (#2764)
- Added support for configuring registry mirrors for base images. This is useful when hitting Docker Hub rate limits. Only public mirrors (such as
mirror.gcr.io
) are supported. (#3011)
- Build will fail if Jib cannot create or read the global Jib configuration file. (#2996)
- Updated jackson dependency version causing compatibility issues. (#2931)
- Deprecated use of
@Optional
on boolean attribute (#2930)
- Added an option
jib.container.expandClasspathDependencies
to preserve the order of loading dependencies as configured in a project. The option enumerates dependency JARs instead of using a wildcard (/app/libs/*
) in the Java runtime classpath for an image entrypoint. (#1871, #1907, #2228, #2733)- The option is also useful for AppCDS. (#2471)
- Turning on the option may result in a very long classpath string, and the OS may not support passing such a long string to JVM.
- Added lazy evaluation for
jib.(to|from).auth.(username|password)
andjib.from.image
using Gradle Property and Provider. (#2905)
- Fixed
NullPointerException
when pulling an OCI base image whose manifest does not havemediaType
information. (#2819) - Fixed build failure when using a Docker daemon base image (
docker://...
) that has duplicate layers. (#2829)
- Added lazy evaluation for
jib.to.image
andjib.to.tags
using Gradle Property and Provider. (#2727) - Incubating feature: can now configure multiple platforms (such as architectures) to build multiple images as a bundle and push as a manifest list (also known as a fat manifest). As an incubating feature, there are certain limitations. For example, OCI image indices are not supported, and building a manifest list is supported only for registry pushing (the
jib
task). (#2523)jib.from { image = '... image reference to a manifest list ...' platforms { platform { architecture = 'arm64' os = 'linux' } } }
- Previous locally cached base image manifests will be ignored, as the caching mechanism changed to enable multi-platform image building. (#2730, #2711)
- Upgraded the ASM library to 9.0 to resolve an issue when auto-inferring main class in Java 15+. (#2776)
- Fixed
NullPointerException
during input validation (in Java 9+) when configuring Jib parameters using certain immutable collections (such asList.of()
). (#2702) - Fixed authentication failure with Azure Container Registry when using "tokens". (#2784)
- Improved authentication flow for base image registry. (#2134)
- Throw
IllegalArgumentException
with an error message instead of throwing aNullPointerException
whenjib.to.tags
is set to a collection containing anull
value. (#2760)
- Fixed an issue that configuring
jib.from.platforms
was always additive to the defaultamd64/linux
platform. (#2783)
- Also tries
.exe
file extension for credential helpers on Windows. (#2527) - New system property
jib.skipExistingImages
(false by default) to skip pushing images (manifests) if the image already exists in the registry. (#2360) - Incubating feature: can now configure desired platform (architecture and OS) to select the matching manifest from a Docker manifest list. Currently supports building only one image. OCI image indices are not supported. (#1567)
jib.from { image = '... image reference to a manifest list ...' platforms { platform { architecture = 'arm64' os = 'linux' } } }
- Fixed reporting a wrong credential helper name when the helper does not exist on Windows. (#2527)
- Fixed
NullPointerException
when the"auths":
section in~/.docker/config.json
has an entry with no"auth":
field. (#2535) - Fixed
NullPointerException
to return a helpful message when a server does not provide any message in certain error cases (400 Bad Request, 404 Not Found, and 405 Method Not Allowed). (#2532) - Now supports sending client certificate (for example, via the
javax.net.ssl.keyStore
andjavax.net.ssl.keyStorePassword
system properties) and thus enabling mutual TLS authentication. (#2585, #2226) - Fixed an issue where Jib cannot infer Kotlin main class that takes no arguments. (#2666)
- Jib Extension Framework! The framework enables anyone to easily extend and tailor the Jib Gradle plugin behavior to their liking. Check out the new Jib Extensions GitHub repository to learn more. (#2401)
- Project dependencies in a multi-module WAR project are now stored in a separate "project dependencies" layer (as currently done for a non-WAR project). (#2450)
- Previous locally cached application layers (
<project root>/target/jib-cache
) will be ignored because of changes to the caching selectors. (#2499)
- Fixed authentication failure with Azure Container Registry when using an identity token defined in the
auths
section of Docker config (~/.docker/config.json
). (#2488)
jib.extraDirectories.paths
closure to allow configuring the source and target of an extra directory. (#1581)
- Fixed the problem not inheriting
USER
container configuration from a base image. (#2421) - Fixed wrong capitalization of JSON properties in a loadable Docker manifest when building a tar image. (#2430)
- Fixed an issue when using a base image whose image creation timestamp contains timezone offset. (#2428)
- Fixed an issue inferring a wrong main class or using an invalid main class (for example, Spring Boot project containing multiple main classes). (#2456)
- Glob pattern support for
jib.extraDirectories.permissions
. (#1200) - Support for image references with both a tag and a digest. (#1481)
- The
DOCKER_CONFIG
environment variable specifying the directory containing docker configs is now checked during credential retrieval. (#1618) - Also tries
.cmd
file extension for credential helpers on Windows. (#2399)
jib.container.creationTime
now accepts more timezone formats:+HHmm
. This allows for easier configuration of creationTime by external systems. (#2320)
- Additionally reads credentials from
~/.docker/.dockerconfigjson
and legacy Docker config (~/.docker/.dockercfg
). Also searches for$HOME/.docker/*
(in addition to currentSystem.get("user.home")/.docker/*
). This may help retrieve credentials, for example, on Kubernetes. (#2260) - New skaffold configuration options that modify how jib's build config is presented to skaffold (#2292):
jib.skaffold.watch.buildIncludes
: a list of build files to watchjib.skaffold.watch.includes
: a list of project files to watchjib.skaffold.watch.excludes
: a list of files to exclude from watchingjib.skaffold.sync.excludes
: a list of files to exclude from sync'ing
- Fixed authentication failure with error
server did not return 'WWW-Authenticate: Bearer' header
in certain cases (for example, on OpenShift). (#2258) - Fixed an issue where using local Docker images (by
docker://...
) on Windows caused an error. (#2270) - Fixed build failures with Skaffold when the Gradle Java Platform plugin is applied. (#2269)
- For Spring Boot projects using
containerizingMode = 'packaged'
, Jib now overridesarchiveClassifier
of thejar
task only when safe and necessary. (#2278) - Fixed an issue where user-configured task dependencies for the Jib task is overwritten and thus ineffective. (#2289)
- Added json output file for image metadata after a build is complete. Writes to
build/jib-image.json
by default, configurable withjib.outputPaths.imageJson
. (#2227) - Added automatic update checks. Jib will now display a message if there is a new version of Jib available. See the privacy page for more details. (#2193)
- Removed
jibDockerBuild.dockerClient
in favor ofjib.dockerClient
. (#1983) - Removed deprecated
jib.extraDirectory
configuration in favor ofjib.extraDirectories
. (#1691) - Removed deprecated
jib.container.useCurrentTimestamp
configuration in favor ofjib.container.creationTime
withUSE_CURRENT_TIMESTAMP
. (#1897) - HTTP redirection URLs are no longer sanitized in order to work around an issue with certain registries that do not conform to HTTP standards. This resolves an issue with using Red Hat OpenShift and Quay registries. (#2106, #1986)
- Requires Gradle 5.1 or newer (up from 4.9).
- The default base image cache location has been changed on MacOS and Windows. (#2216)
- MacOS (
$XDG_CACHE_HOME
defined): from$XDG_CACHE_HOME/google-cloud-tools-java/jib/
to$XDG_CACHE_HOME/Google/Jib/
- MacOS (
$XDG_CACHE_HOME
not defined): from$HOME/Library/Application Support/google-cloud-tools-java/jib/
to$HOME/Library/Caches/Google/Jib/
- Windows (
$XDG_CACHE_HOME
defined): from$XDG_CACHE_HOME\google-cloud-tools-java\jib\
to$XDG_CACHE_HOME\Google\Jib\Cache\
- Windows (
$XDG_CACHE_HOME
not defined): from%LOCALAPPDATA%\google-cloud-tools-java\jib\
to%LOCALAPPDATA%\Google\Jib\Cache\
- Initial builds will be slower until the cache is repopulated, unless you manually move the cache from the old location to the new location
- MacOS (
jibBuildTar
withjib.container.format='OCI'
now builds a correctly formatted OCI archive. (#2124)- Now
jib.containerizingMode='packaged'
works as intended with Spring Boot projects that generate a fat JAR. (#2178) - Now automatically refreshes Docker registry authentication tokens when expired, fixing the issue that long-running builds may fail with "401 unauthorized." (#691)
- Requires Gradle 4.9 or newer (up from 4.6).
- Optimized building to a registry with local base images. (#1913)
- Fixed reporting parent build file when
skaffold init
is run on multi-module projects. (#2091) - Now correctly uses the
war
task if it is enabled and thebootWar
task is disabled for Spring WAR projects. (#2096) allowInsecureRegistries
and thesendCredentialsOverHttp
system property are now effective for authentication service server connections. (#2074)- Fixed inefficient communications when interacting with insecure registries and servers (when
allowInsecureRegistries
is set). (#946)
jib.outputPaths
object for configuration output file locations (#1561)jib.outputPaths.tar
configures output path ofjibBuildTar
(build/jib-image.tar
by default)jib.outputPaths.digest
configures the output path of the image digest (build/jib-image.digest
by default)jib.outputPaths.imageId
configures output path of the image id (build/jib-image.id
by default)
- Main class inference support for Java 13/14. (#2015)
- Local base image layers are now processed in parallel, speeding up builds using large local base images. (#1913)
- The base image manifest is no longer pulled from the registry if a digest is provided and the manifest is already cached. (#1881)
- Docker daemon base images are now cached more effectively, speeding up builds using
docker://
base images. (#1912)
- Fixed temporary directory cleanup during builds using local base images. (#2016)
- Fixed additional tags being ignored when building to a tarball. (#2043)
- Fixed
tar://
base image failing if tar does not contain explicit directory entries. (#2067)
- Fixed an issue with using custom base images in Java 12+ projects. (#1995)
- Support for local base images by prefixing
jib.from.image
withdocker://
to build from a docker daemon image, ortar://
to build from a tarball image. (#1468, #1905)
- To disable parallel execution, the property
jib.serialize
should be used instead ofjibSerialize
. (#1968) - For retrieving credentials from Docker config (
~/.docker/config.json
),credHelpers
now takes precedence overcredsStore
, followed byauths
. (#1958) - The legacy
credsStore
no longer requires defining empty registry entries inauths
to be used. This now means that ifcredsStore
is defined,auths
will be completely ignored. (#1958) jib.dockerClient
is now configurable on all tasks, not justjibDockerBuild
. (#1932)jibDockerBuild.dockerClient
is deprecated in favor ofjib.dockerClient
.
- Fixed the regression of slow network operations introduced at 1.5.0. (#1980)
- Fixed an issue where connection timeout sometimes fell back to attempting plain HTTP (non-HTTPS) requests when
allowInsecureRegistries
is set. (#1949)
- Fixed an issue interacting with certain registries due to changes to URL handling in the underlying Apache HttpClient library. (#1924)
- Can now set timestamps (last modified time) of the files in the built image with
jib.container.filesModificationTime
. The value should either beEPOCH_PLUS_SECOND
to set the timestamps to Epoch + 1 second (default behavior), or an ISO 8601 date time parsable withDateTimeFormatter.ISO_DATE_TIME
such as2019-07-15T10:15:30+09:00
or2011-12-03T22:42:05Z
. (#1818) - Can now set container creation timestamp with
jib.container.creationTime
. The value should beEPOCH
,USE_CURRENT_TIMESTAMP
, or an ISO 8601 date time. (#1609) - For Google Container Registry (gcr.io), Jib now tries Google Application Default Credentials (ADC) last when no credentials can be retrieved. ADC are available on many Google Cloud Platform (GCP) environments (such as Google Cloud Build, Google Compute Engine, Google Kubernetes Engine, and Google App Engine). Application Default Credentials can also be configured with
gcloud auth application-default login
locally or through theGOOGLE_APPLICATION_CREDENTIALS
environment variable. (#1902)
- When building to a registry, Jib now skips downloading and caching base image layers that already exist in the target registry. This feature will be particularly useful in CI/CD environments. However, if you want to force caching base image layers locally, set the system property
-Djib.alwaysCacheBaseImage=true
. (#1840) jib.container.useCurrentTimestamp
has been deprecated in favor ofjib.container.creationTime
withUSE_CURRENT_TIMESTAMP
. (#1609)
- Can now containerize a JAR artifact instead of putting individual
.class
and resource files withjib.containerizingMode = 'packaged'
. (#1760) - Now automatically supports WAR created by the Spring Boot Gradle Plugin via the
bootWar
task. (#1786) - Can now use
jib.from.image = 'scratch'
to use the scratch (empty) base image for builds. (#1794)
- Dependencies are now split into three layers: dependencies, snapshots dependencies, project dependencies. (#1724)
- Re-enabled cross-repository blob mounts. (#1793)
- Manifest lists referenced directly by sha256 are automatically parsed and the first
linux/amd64
manifest is used. (#1811)
- Docker credentials (
~/.docker/config.json
) are now given priority over registry-based inferred credential helpers. (#1704)
- Fixed an issue with
jibBuildTar
whereUP-TO-DATE
checks were incorrect. (#1757)
- Container configurations in the base image are now propagated when registry uses the old V2 image manifest, schema version 1 (such as Quay). (#1641)
- Can now prepend paths in the container to the computed classpath with
jib.container.extraClasspath
. (#1642) - Can now build in offline mode using
--offline
. (#718) - Now supports multiple extra directories with
jib.extraDirectories.{paths|.permissions}
. (#1020)
jib.extraDirectory({.path|.permissions})
are deprecated in favor of the newjib.extraDirectories.{paths|.permissions}
configurations. (#1671)
- Labels in the base image are now propagated. (#1643)
- Fixed an issue with using OCI base images. (#1683)
- Fixed an issue where automatically generated parent directories in a layer did not get their timestamp configured correctly to epoch + 1s. (#1648)
- Fixed an issue where the plugin creates wrong images by adding base image layers in reverse order when registry uses the old V2 image manifest, schema version 1 (such as Quay). (#1627)
os
andarchitecture
are taken from base image. (#1564)
- Fixed an issue where pushing to Docker Hub fails when the host part of an image reference is
docker.io
. (#1549)
- Java 9+ WAR projects are now supported and run on the distroless Jetty Java 11 image (https://github.com/GoogleContainerTools/distroless) by default. Java 8 projects remain on the distroless Jetty Java 8 image. (#1510)
- Now supports authentication against Azure Container Registry using
docker-credential-acr-*
credential helpers. (#1490)
- Fixed an issue where setting
allowInsecureRegistries
may fail to try HTTP. (#1517) - Crash on talking to servers that do not set the
Content-Length
HTTP header or send an incorrect value. (#1512)
- Java 9+ projects are now supported and run on the distroless Java 11 image (https://github.com/GoogleContainerTools/distroless) by default. Java 8 projects remain on the distroless Java 8 image. (#1279)
- Failure to infer main class when main method is defined using varargs (i.e.
public static void main(String... args)
). (#1456)
- Shortened progress bar display - make sure console window is at least 50 characters wide or progress bar display can be messy. (#1361)
- Setting proxy credentials (via system properties
http(s).proxyUser
andhttp(s).proxyPassword
) is now supported.
- Java 9+ projects using the default distroless Java 8 base image will now fail to build. (#1143)
jib.baseImageCache
andjib.applicationCache
system properties for setting cache directories. (#1238)- Build progress shown via a progress bar - set
-Djib.console=plain
to show progress as log messages. (#1297)
- Removed
jib.useOnlyProjectCache
parameter in favor of thejib.useOnlyProjectCache
system property. (#1308)
- Builds failing due to dependency JARs with the same name. (#810)
- Image ID is now written to
