Total Newbie

[Eric Kolotyluk]

Hi, forgive me, I am a total newbie to error-prone...

Is there any easy way to verify that error-prone is actually configured correctly and working?

I have updated my Gradle configuration to use error-prone, as well as InelliJ, but there does not seem to be any way I can verify things are actually using error-prone. Building with either Gradle or IntelliJ does not show error-prone being invoked.

Any help would be greatly appreciated.

Hi,

One way to confirm that it's configured would be to modify the sources in the project to introduce something that Error Prone would report a diagnostic for, e.g. if you add a statement like `new AssertionError();` and rebuild you should see a diagnostic from this check.

Okay, that did the trick... thanks so much.
