I have a maven multi module project and I want my build to fail if code coverage is insufficient.

I'm using jacoco maven plugin for this, I had no problem with local builds but when building my project on Jenkins I have found jacoco reports to be inconsistent.

This is a blocking problem to me because the build fails when coverage expectations are not met.

Here's two extract of failed build with no SCM changes between them.

build #89

[WARNING] Insufficient code coverage for COMPLEXITY: 60,52% < 63,14%
[WARNING] Insufficient code coverage for METHOD: 64,28% < 67,84%

build #90

[WARNING] Insufficient code coverage for BRANCH: 70,00% < 75,00%
[WARNING] Insufficient code coverage for COMPLEXITY: 57,89% < 63,14%
[WARNING] Insufficient code coverage for METHOD: 64,28% < 67,84%

Previous build was successful with the same code coverage expectations.

I have tried with different jacoco versions (0.6.2.201302030002 and 0.6.3.201306030806) without luck.

I have reported this problem in jenkins issue tracker since I have only seen it my Jenkins build and not in my local builds but I may be wrong.

I understand this is not easy to fix or investigate, I just thought it was important to report it.

Kind regards,

Joel
