Jacoco plugin shows no coverage with dumped file from jacoco java agent

[rui.a.r...@gmail.com]

Hello,

I'm using the jacoco java agent to dump the coverage of my integration tests (via jmx call) to a file and then use it with jenkins' jacoco plugin to show the coverage trend column. The following command line is used:

 -javaagent:org.jacoco.agent-0.7.6.201602180812-runtime.jar=destfile=/tmp/var/itjacoco.exec,jmx=true,append=false

Since the application has several components (several jars in classpath), the exec file is copied to each component's work space and when the component is built, the coverage is collected by the jacoco plugin.

As you can see below, the jacoco plugin collects 2 files: the one from IT tests and the one from unit tests. But only the coverage of the unit tests are shown. If I comment the unit tests, the coverage is zero.

Any idea what can be wrong?

This was working last week when this job was running on windows. Now this job runs in a linux slave machine.

Jacoco plugin used: 2.0.1

Thanks
