Missing generatedSourceOutputDirectory for delombok sourcepath

[AlexProgrammerDE]

Hi, I'm using immutables in my app alongside delombok.
When I compile my app the delombok task outputs these error messages:

10:12:48 /home/jenkins/workspace/AlexProgrammerDE/SoulFire/server/src/main/java/com/soulfiremc/server/plugins/AutoEat.java:27: error: cannot find symbol
10:12:48 import com.soulfiremc.server.settings.property.ImmutableBooleanProperty;

...and many more files....

This is because delombok is missing generated sources by annotation processors in the sourcepath. I've fixed these error messages by doing:

tasks {
  delombok {
    sourcepath.setFrom(sourcepath.plus(compileJava.get().options.generatedSourceOutputDirectory))
  }
}

in my buildscript. I'd like to ask that the generated source output directory should also be added to the sourcepath by default.
