sourceSet other than `main` won't output

When I run gradle, it generates output files for the proto-files. These are put into $projectDir/src/$sourceSet/java/my/org/models/a.kt (or a.java). This works for the sourceSet main, but not for other sourceSets like commonMain, although I defined the task for all sourceSets. The protofiles and directories are identical between sourceSet main and commonMain (I created main just for testing).

Partial gradle build file here (https://gist.github.com/RdeWilde/ec3a5c9432004579643a47ed5fee3397)

Directory structure is:

src
+ commonMain
|    |
|    + java     // no output  :-(
|    + proto
|         |
|         + protofile1.proto
|         + protofile2.proto
|
+ main
     |
     + java    // does have output  :-)
     + proto
          |
          + protofile1.proto
          + protofile2.proto

I took some time to track down the issue I filed related to this. Linking it here for visibility KT-29156

I dont see this getting resolved anytime soon but its worth centralizing the history here at the very least.

Sorry that was a typo. I meant to say that the protobuf plugin would have to be made aware of the kotlin multiplatform plugin. I dont think the source set would need to explicitly implement ExtensionAware. Once its created by the object factory, the proxy that wraps the class will implicitly add it.
