NPE with svn version of surefire-report-maven-plugin

Just to clarify, other reports work fine (eg javadoc), and it's not that the report is empty - you can click on the surefire report. The report just doesn't pick up on the tests at all, saying there were 0 tests.

Hi Julian,

I can't duplicate this issue. I have tried doing the steps u listed and can't duplicate the error. I am wondering if this error is related to surefire report.

Just to be sure, please do "mvn install -DupdateReleaseInfo=true" on the latest svn of surefire-report plugin.

And try it again but this time do this "mvn site -e". Please post the result .

I am using maven version 2.0 and surefire-report 2.0-beta-2-SNAPSHOT on my tests.

Cheers,
Johnny

I downloaded the surefire report tarball from the mojo svn as above (rev 749 - where is the actual svn repository for these mojo's, so that I can svn co), and installed it as directed:

mvn install -DupdateReleaseInfo=true

Then I built a new project as outlined above, adding in the single report. Same error:

I'm using maven version 2.0 and surefire-report 2.0-beta-2-SNAPSHOT as well. The reason I think it's the surefire report is because I can omit that one report and the site builds fine. I can substitute it with a different report and it works fine. I can change to 2.0 beta 1 of the surefire report and the site builds fine, though the surefire report fails to report properly on the tests performed.

BTW, mvn site -e was the same, minus a little bit of information.

Thanks for looking at this!

I've started to track this issue down a little further. I've built maven from svn (2.0.1-SNAPSHOT) and reproduced the issue again.

I've confirmed that the List of MojoDescriptor (pluginDescriptor.getMojos()) is null when the reportPlugin is surefire-report-maven-plugin, whereas for any other report there is a valid List - this is in DefaultLifecycleExecutor as specified in the stacktrace.

Now I'm starting to look into why it's null, but this is leading me into plexus. Is this ringing any bells? Is some additional config required somewhere for this report?

So there seems to be two problems: why is the List null, and if it is null, should it be handled better?

Thanks,

J

Hi Julian,

I can't really duplicate the error. Anyway, here is the svn repository of surefire-report plugin. --> https://svn.codehaus.org/mojo/trunk/mojo/surefire-report-maven-plugin/

Check it out and mvn install -DupdateReleaseInfo=true

If it still doesn't work, maybe you can attach here a sample project that creates the error so we can try it out. Good Luck!

OK I've got this working now. I'm still not sure exactly what causes the problem, but if I build the site under bash, rather than tcsh, everything is okay. Same .profile for each (adjusted for syntax, of course), so the env is identical. I don't know what causes that NPE under tcsh, but whatever - I'm happy using bash.

Thanks,

J
