[MSHADE-304] Include specific files or directories for transformation - IncludeResourceTransformer?

**[Alex](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=exas)** opened **[MSHADE-304](https://issues.apache.org/jira/browse/MSHADE-304?redirect=false)** and commented

**Background**
I am working at a project with the DI framework HK2.

With HK2 it is possible to use _hk2-metadata-generator_ to generate a file ("META-INF/hk2-locator/default") containing all annotated `@Service` classes (and `@ConfiguredBy` annotations)  for the auto-discovery feature in HK2.

For the configuration part (`@ConfiguredBy`) of HK2 i am using maven dependency hk2-configuration-integration (org.glassfish.hk2).

See for more details also:
https://javaee.github.io/hk2/configuration.html
https://javaee.github.io/hk2/inhabitant-generator.html

Example `@ConfiguredBy` annotation: https://github.com/eclipse-ee4j/glassfish-hk2/tree/master/examples/configuration 

 

**Issue/Improvement**

With maven-shade i was able to configure relocation for specific dependencies which might be conflicting when used in other projects, which is a really cool feature i have to say!

Only one manual step is now necessary for me (scripted at the moment) to adapt the generated file "META-INF/hk2-locator/default" and update the JAR to have a proper working JAR.
See also attached example file [^default] (note the org.glassfish.hk2 scope defined there, which would require transformation/renaming i.e. org.shaded.glassfish..).

 

Maybe i am missing something which already exists with maven shade plugin, but i was not able to include a custom file to the transformation/relocation process, like in my described situation.

I also tried to use "IncludeResourceTransformer" but when looking at the code no transformation is done there, it is just used for copying artifacts as far as i can tell? The name is a bit misleading, isn't it?

Start with IncludeResourceTransformer and the attached META-INF/hk2-locator/default example, then review how Maven Shade applies relocation to dependencies. Determine how a selected file or directory could participate in transformation and define completion as producing a shaded JAR whose HK2 metadata reflects the configured relocation.
