Hi,

I’m trying to build Gradle from sources (current master) and hit some problems:

SamplesToolingApiIntegrationTest in :tooling-api:integTest are failing due some Javac bug - [https://gist.github.com/radimk/7143446](https://gist.github.com/radimk/7143446) Debian Linux, JDK6u45. Is this a know problem? Any way how to avoid that?

MavenConversionIntegrationTest in :buildInit:integTest fails if I keep my ~/.m2/settings.xml in place. It sets up a mirror for Maven central repository. Pretty much same confing as in [http://books.sonatype.com/nexus-book/reference/maven-sect-single-group.html](http://books.sonatype.com/nexus-book/reference/maven-sect-single-group.html) with servers section added to specify authentication for this Nexus. Test output shows that my Nexus responds with 401 to requests performed during test run. I can temporarily move the file but it would be better if I could make the test more robust.

:performance:integTest - I don’t know what is the problem here yet. There are some outliers in the results but sometimes measured values are really above accepted threshold.

SamplesToolingApiIntegrationTest: use a newer (or perhaps older) JDK. Not sure about MavenConversionIntegrationTest; pull requests are welcome. And perhaps run performance tests separately (or not at all). We only run them on CI, and only on a dedicated performance test agent.

The test is bugged. They aren’t using the necessary test fixtures. Which tests are failing?

These tests currently are failing.

MavenConversionIntegrationTest. enforcerplugin MavenConversionIntegrationTest. singleModule MavenConversionIntegrationTest. testjar are failing.

I’ll check if I can isolate the problem with javac and see if changing JDK helps.

I thought that I can try performance tests again at some point with more controlled environment (use my desktop or turn off CPU frequency adjusting).

Thanks.
