HELP: Unit test failing in Jenkins when building gradle-os-plugin

[sc1478]

I am working on a revision to the gradle-os-package plugin. When building on an ordinary linux server, the plugin builds without error, including all of my changes, which, in any case, only affect the RPM plugin.

When running the same build under Jenkins, the following tests fail, and I am trying to understand why. The error messages don't help me much:

:testJava HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

* What went wrong:

To get a little more detail, I see stack traces like the following, while looking the report linked above. All of the failed test fail because of the same error:

Let me reiterate, on an ordinary Linux server, with the same code base, these errors do not occur. Also, my only code change was on the rpm plugin, yet 5 of these 6 errors are tests of the deb plugin which I've left utterly alone. Therefore I conclude that something is different in my jenkins environment than in my ordinary linux environment. But what might that be? I don't know enough about this test suite or about jenkins (newbie) to venture a guess. The only clue I see is

Caused by: groovy.lang.MissingPropertyException: Could not find property 'com' on root project 'not-up-to-date-when-specifying-any-value'.

But I don't know what could be causing this, and I'm hoping someone here can give me a clue.

Thanks.

My non-forked version builds fine with Jenkins. I should have tried that first. Let me try to retrace my steps and see what I did wrong. Still can't account for difference between running on plain linux server vs running on Jenkins though. If these error message make sense to anyone, I'd still like an informed opinion, thanks.

OK, please close this. The same problem occurs without jenkins. Last week it built and I can't see any changes.
