Great! There were people getting burned by this at EclipseCon. Luckily, I remembered this bug and was able to help them but now we don't have to.

There is a bug in gradle 1.11 (already fixed in 1.12-rc1) which would be intrusive to workaround, so 1.11 is now blacklisted.

The logic is this:

if (gradleVersion != "1.8") {
   if (gradleVersion < "1.8") fail
   else if (gradleVersion == "1.11") fail
   else warn

You can turn the failures into warnings with "gradle -PGRADLE_VERSION_CHECK=false"

I suggest that if we can't fix the bug quickly, we print out a message that we require gradle 1.8 and exit. We should let people override this choice in the properties file.

Leonid just happened to be running an older gradle.

Was this gradle 1.8 or a problem with an EA version of JDK8? In any case, update both. If you can't, doing a clean every time should work but that's not the long term answer.

Are you using gradle 1.8? This looks like a bug we used to have with prior versions of gradle.
