Good find! I see that this bug is most likely the issue: https://issues.apache.org/bugzilla/show_bug.cgi?id=54090
From this bug report it looks like the "depend" feature we have turned on by default is causing the problem. You can turn USE_DEPEND=false. This will cause your build times to become longer if you do all your builds from the command line. If you predominantly develop in the IDE, this won't be a problem since you are probably doing a full clean / build on the command line anyway, and only before you push. If you predominantly do all builds from the command line, then you're going to see your build times get worse with this workaround. I posted this question to the gradle guys: http://forums.gradle.org/gradle/topics/gradles_ant_dependency_needs_to_be_updated_to_work_with_java_8_ant_will_report_invalid_constant_pool_entry_type?rfm=1 Hopefully we can see the ant version get a bump in their 1.7 release. If so, we will need to upgrade our build systems to use Gradle 1.7 I don't think changing the build.compiler flag will work? Maybe it will, I just don't know.
