Hi Peter, It would be even better if I can get Jacoco to work instead of emma and cobertura.
I have looked at the sources last week but could not figure a way to merge the reports of multiple projects into one. Since Jacoco is not mentionned in the guide, I thought support was still incomplete. Can you give me an example of using Jacoco on multiple projects and merging reports? On a side note, anybody has implemented a plugin for integrating with coveralls.io?
