Exclude AutoValue java files from jar

[tobrun]

Ticketing this out as we didn't have a public ticket tracking this: currently AutoValue enabled dependencies from this repo will include generate java files as part of the jar generated.

Capturing from upstream that this is unneeded and these files can safely be removed:

• AutoValue java files could be found in the APK google/auto#706

Considering we aren't able to bump to gradle 5.0 due to java 8 requirement, we should find a way to exclude this files. Either through a gradle configuration or pom.xml configuration or ..

Got some movement but still have to figure out when and how to invoke it.

Adding the following to build.gradle (in directions for example)

tasks.withType(Jar) {
  println '>>>>>>>>>> DIRECTIONS JAR >>>>>>>>>'
  source.each({
    if (it.toString().endsWith('.java')) {
      println '>>>>>>' + it
      exclude(it.toString())
    }})
    println 'excludes=' +excludes
}

Results java files being listed and added to the excludes list BUT for some reason that task is being invoked during ./gradlew clean and not druing .gradlew test
