Command Junit throws NPE

[stbischof]

i tried to run bnd.jar junit on this https://github.com/bndtools/bnd/tree/master/biz.aQute.launchpad.tests

this results in:

Errors

001: NullPointerException

seems that the prepare method of https://github.com/bndtools/bnd/blob/master/biz.aQute.bndlib/src/aQute/bnd/build/JUnitLauncher.java is never called.

To run those tests, run ./gradlew :biz.aQute.launchpad.tests:test.

I don't know anything about the bnd junit command or if it is tested or even works. Looking at JUnitLauncher, it seems somewhat incorrect in multiple ways. I think it is basically dead code.

[stbischof]

There are some people that like bnd command's more than grade. They came up with the question about this command. So i though easiest way to test is project.. just to have something to reproduce the problem.

But i think we should either fix this or remove the command.

Afaik they use the paralle build and run command quiet often.

[bjhargrave]

If the command is broken, then it can certainly be fixed and some tests added to make sure it stays fixed.

As for the Bnd build itself, you must use the gradle build to build and test Bnd.
