JaCoCo maven plugin - code coverage for external jars sources

[tom....@intigua.com]

I got a maven root project, under which there are many independent modules (e.g. module_A, module_B, etc.).

One of these module is my integration-tests module, and it uses (as maven dependencies) ALL the external modules.

I wish jacoco maven plugin to extend its code coverage to every single class in the above external modules. HOWEVER, it seems like its default behavior doesn’t allow this, as it can't access the external sources.

I managed to overcome this with a quick-n'-dirty use of maven-antrun-plugin, Jacoco report Ant Task, and antcontrib (see http://intellectualcramps.wordpress.com/2012/03/22/jacoco-tycho-and-coverage-reports/)... It does the job - but it's not good enough.

Does jacoco maven plugin has its own feature for doing so, without using ant?

Thanks!
Tom

Hi Tom,

this is a open issue since long time: The JaCoCo Maven plug-in currently
only supports code coverage for single modules.

Cheers,

I was afraid that's the case.
Could you please refer me to the specific open issue?
Thanks!
