Thanks for letting us know. For now, ‘test.scanForTestClasses = false’ should solve the problem.

pie_or_paj · November 14, 2013, 2:43pm

I have the same problem using the latest (1.9-rc-3) version. test.scanForTestClasses = false doesn’t work for me as it makes my tests fail on inner classes that aren’t test classes at al, just used for mocking.

Peter_Niederwieser · November 14, 2013, 3:18pm

Gradle itself can’t be run with Java 8 yet, as some of its underlying libraries don’t yet support Java 8.

Elias_Vasylenko · January 7, 2014, 5:41pm

Just for the record, I’ve been having this exact same problem and it seems to be fixed with the latest nightly build. ( 1.11-20140107005627+0000 ) Not sure when exactly the fix happened though as I’ve not been upgrading that regularly. Thanks guys!

luke_daley · January 7, 2014, 6:13pm

We upgraded to a new version of ASM, which supports Java 8 bytecode.

Elias_Vasylenko · January 7, 2014, 7:23pm

Fantastic :). I thought you’d probably be aware of it considering the nature of the problem, but this page still comes up early in google results so I figured it wouldn’t hurt to comment.

Thanks again!

Renato_Athaydes · February 28, 2014, 11:33pm

Just installed Gradle 1.11 and it works with Java 8. Great job.
