Github user kenmy commented on the issue: https://github.com/apache/flink/pull/2836 I have tryed to collect coverage by this approach. During my attempt I rebased this PR into e187b5ee9aa6d1bf9feec151ff460d1a28c4e5f0 (master in apach/flink at the yesterday evening). And share [result](https://drive.google.com/file/d/0B5g8DD_NcAW0MzFJQWFVYXdSWDA/view?usp=sharing) via gdrive. My branch is [here](https://github.com/kenmy/flink/tree/JacocoCoverage). I am not sure that did anything right because haven't checked added projects since this PR. I hope is will help to resolve conflicts faster.
