Reported by Google:
Removing a source file in the main sources breaks incremental compilation of the test sources.

Reproduction Steps

You just need a project with
apply plugin: 'java'
configure([compileJava, compileTestJava])

{ options.incremental = true }


and two valid java files in src/main/java and one in src/test/java.
compile, and then remove one of the files from src/main/java

`gradlew build` output:
: Incremental java compilation is an incubating feature.
None of the classes needs to be compiled! Analysis took 0.006 secs.
:processResources UP-TO-DATE
:compileTestJava FAILED

FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ':compileTestJava'.
    > Unable to read class file: '/usr/local/google/home/cmw/sample/build/classes/main/com/example/Foo.class'
  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
