Coverage is only for ipr runners, right?

Just click on the "Enable code coverage" button at the bottom of the Ant runner config. We've been getting coverage for our Ant-based builds for over a year, now.

Thanks, I've overlooked it..

Anyway, my build fails if coverage is enabled... with the message like this:

BUILD FAILED C:\TeamCity\buildAgent\work\project\ant-tasks.xml:31: taskdef A class needed by class MergeProperties cannot be found: com/vladium/emma/rt/RT Total time: 1 minute 0 seconds
: Process exit code: 1
: Artifacts path coverage.ec not found
: Artifacts path coverage.txt not found
: Artifacts path coverage not found

The script compiles ant tasts with javac and then uses them with taskdef. It seems that 'javac' task is somehow tweaked so that compiled classes reference emma runtime... Does anyone have an idea how to fix that?

Hello,

When coverage is enabled TeamCity patches javac task and performes code
instrumentation. Then to run instrumented classess a special jar file is
required. This jar file is passed transparently to Ant tasks starting tests,
but currently it can't do this if you launch compiled custom tasks. I think
you can try to add emma.jar in classpath of your taskdef. You can refer to
it in Ant script as follows:
${agent.work.dir}/../plugins/coveragePlugin/lib/emma.jar

agent.work.dir property will be provided by TeamCity Ant runner.

I cannot modify all parts of the build that contain ]]> task...
I've tried adding emma.jar to global classpath.
It passes futher but there is interference with custom Ant tasks:

Custom task creates a new Ant target, adds it to the project and tries to execute it with project.executeTarget()

Igor,

What version of the Ant do you use? Code coverage should work only with Ant 1.6.5+ . If you use one of these versions, please file a Jira issue regarding the problem.

thanks,
KIR

It is definitely Ant 1.6.5+, coverage works for other configurations of the same project.

Igor,

I've fixed this particular NPE and the fix will be available in the next EAP build for TeamCity 3.1.

Hope it will fix your problem,

Regards,
KIR
