I'm trying to develop XML-based software. I'm using Maven & XmlBeans.

I have a base-project which provides base-xml-schemas which define some elements, abstract types, etc,.

All other sub-projects also provides xml-schemas. But, these sub-projects imports/refers the base-xml-schemas to use & extend the elements / types defined by base-schemas.

Even though my sub-projects depends on base-project, xmlbeans plugin requires the base-xml-schemas to be present in schemaDirectory for its usage. As an implication, all my sub-projects now carry the duplicate content generated/compiled due to base-xml-schemas.

I want my sub-projects to have only those sub-project-specific schemas & content in their jar, as My base-project will be available to all applications in my Jboss & the types can be resolved in runtime.

Having understood that the xmlbean needs all the schemas referred to be present for code generation, now I want to delete all xmlbean-generated code due to the present of base-xml-schema and retain files related to sub-project specific schemas.

I have manually done this and my project compilation & runtime works fine, as my maven has dependency & classes are available in runtime.

My question is - How to automate this using maven so the files generated due to base-schema is deleted just after generation.

Maven xmlbeans plugin binds by default to the lifecycle phase: generate-sources.

You will need to bind clean goal of the clean plugin to the above lifecycle phase.

Refer to the link - Remove or delete resource files from target directory using pom file

Configuration will be like this: 

      <execution>
        <id>clean-autogenerated-code</id>
        <phase>generate-sources</phase>
        <goals>
          <goal>clean</goal>
        </goals>
        <configuration>
         <filesets>
            <fileset>
              <directory>some/relative/path/location/of/autogeneratd/code</directory>
            </fileset>
          </filesets>
        </configuration>
    </execution>

directory location - provide exact directory location of the auto-generated classes.

This you will need to configure in your all sub-projects from where you need to delete your auto-generated xml beans files. If you have any parent-pom all of your sub-projects, configure in that pom.xml file.
