Hi,
I've been trying to create a coverage report for a multimodule maven project, but the current mojos provided by the Maven plugin do not quite cover satisfy my needs: be able to gather all execution data files and all the source classes in a single report.
In order to provide something simpler, I created an aggregator Maven plugin to collect all data executions and source/class file locations in order to generate the report. The code is available as a pull request
https://github.com/jacoco/jacoco/pull/1115, and of course, feedback is very welcome.
Cheers,
Laurent
