Error-prone: -XepExcludedPaths causes exception

[krisztiankocsis]

Hi!

I'm using Error Prone in a Gradle project and wanted to exclude generated sources from Error Prone checks. I've added '-XepExcludedPaths:./build/generated/.' to the compiler arguments but then it causes an exception:

• What went wrong:
  Execution failed for task ':planny-center:compileJava'.

  java.lang.reflect.InvocationTargetException

• Try:
  Run with --info or --debug option to get more log output.

• Exception is:
  org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':planny-center:compileJava'.

[msridhar]

Just checking, did you build EP master from source? This flag has not made it to a release yet.

[krisztiankocsis]

Hi, I thought that it was released because the flag is documented here: http://errorprone.info/docs/flags

[msridhar]

Ah yes, the documentation change already landed. @cushon is there a release planned soon? If not, maybe we should revert the doc change until the new release comes out

[cushon]

I commented out the docs for now.

[magneticflux-]

When do you think a release could be expected? I'm dealing with lots of spurious warnings from the Room annotation processor running with kapt because the generated classes aren't properly tagged with @Generated.

[eaftan]

@nglorioso is going to start a release. It should be out by the end of this week.

[NickButcher1]

Is there any update on when the release will be available?

[eaftan]

It's available now :)
