[WARNING] Unknown keyword additionalItems - you should define your own Meta Schema. If the keyword is irrelevant for validation, just use a NonValidationKeyword

warning that appears in cyclone-dx-maven plugin when validating the json SBOM that just has been generated: see CycloneDX/cyclonedx-maven-plugin#305

it seems this is a problem when parsing the json schema https://github.com/CycloneDX/cyclonedx-core-java/blob/master/src/main/resources/bom-1.4.schema.json

Any means to circumvent this problem?

[stevespringett]

Likely caused by minor technical defects in prior schemas. These warnings can simply be ignored. I believe we have eliminated these issues in v1.5

It stills occures with current core version (7.3.2 used by Maven CycloneDX-Plugin 2.7.9, released May 2023). So it was not fixed in 7.1.5 :/

[stevespringett]

@Bukama we never said it was fixed in cyclonedx-core-java. What was said was that we have fixed the issue in v1.5 of the CycloneDX schema. We have yet to release a version of cyclonedx-core-java that supports the v1.5 schema, but we're close to doing so. The next point release will include support for the v1.5 schema, so generating BOMs with that schema should not yield any warnings, however generating BOMs targeting CycloneDX v1.4 will continue to generate the warnings (as expected).

Thanks for the clarification. I understood your comment as a reference to the 7.1.5 version, my bad!

Hi, still happens in maven plugin 2.7.11 with core 8.0.3. Any hope we can get it fixed soon?

[hboutemy]

@rmannibucau maven plugin 2.7.11 does not use core 8 but 7: maven 2.8 will use code 8, currently available as SNAPSHOT only

[rmannibucau]

Thanks @hboutemy , I can confirm there is no more warning with the snapshot.
Any release date?

[hboutemy]

it should come soon, a few improvements to add before

[garydgregory]

Is there a status update available please?

[hboutemy]

just tested with cyclonedx-core-java 9.1.0, still same warning on keywords meta:enum and deprecated

• symptoms:

git clone https://gitbox.apache.org/repos/asf/commons-cli
cd commons-cli
mvn clean verify -Dcommons.cyclonedx.version=2.9.1-SNAPSHOT -DskipTests

• code causing the warnings: https://github.com/networknt/json-schema-validator/blob/2fb347ec65b2c950017de7fa79be165b0995ae91/src/main/java/com/networknt/schema/UnknownKeywordFactory.java#L38

I still don't get how to improve cyclonedx-core-java:
I find 12 deprecated and 32 meta:enum in https://github.com/CycloneDX/cyclonedx-core-java/blob/master/src/main/resources/bom-1.6.schema.json

should this schema be updated? should the code be updated to not warn on such case? how?
guidance appreciated

[stevespringett]

meta:enum is a workaround for limitations in JSON schema. It is supported by Adobe and many other third-party tools, however, it is not part of JSON Schema. There is a possibility that other meta:* may be used in future versions of the specification. IMO, you may want to suppress these warnings that are known and will not be removed from the specification.
