Fabric8 CRD Yaml to Java Generator Demo

Demo project that showcases generating java POJO from CRD YAML using Fabric8 Java Generator Maven Plugin.

Project contains YAML for Book CustomResourceDefinition:

fabric8-crd-java-generator-demo : $ tree src/main/resources/
src/main/resources/
└── crd
    └── book-crd.yaml

Add Fabric8 Java Generator Maven Plugin to pom.xml:

<plugin>
    <groupId>io.fabric8</groupId>
    <artifactId>java-generator-maven-plugin</artifactId>
    <version>${fabric8.version}</version>
    <configuration>
        <!-- 1 -->
        <source>${project.basedir}/src/main/resources/crd/book-crd.yaml</source> 
         <!-- 2 -->
        <extraAnnotations>true</extraAnnotations>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
</plugin>

1. Source file or directory from which to generate POJOs
2. Add extra Sundrio annotations for generating builder, fluent classes.

Build project:

fabric8-crd-java-generator-demo : $ mvn clean install

POJOs should be generated in target/generated-sources folder:

fabric8-crd-java-generator-demo : $ tree target/generated-sources/java/
target/generated-sources/java/
└── io
    └── fabric8
        └── demo
            └── generator
                └── v1alpha1
                    ├── Book.java
                    ├── BookSpec.java
                    └── BookStatus.java
