Gradle build progress

OK, I just pushed a fix for this that should show up in 20min or so. Now I'm getting a failure when compiling the tests for Controls, which is a crash in javac. I've filed this as JDK-8010659 and have spent the whole day so far trying to track this one down. I think this is the only thing preventing all the tests from running.

Which means, we can build, test (almost), and produce javadoc. And I also added the IDEA project file generation. I was wondering if Tom or somebody using Eclipse would want to try their hand at the eclipse project file creation? I'm about to send an email to the NB guys as well. Hopefully we'll have IDE support ready to go here shortly as well.
