JaCoCo maven-plugin and JaCoCo Agent

[Frank Krumm]

Hi,

I want to check code coverage on external weblogic.

I have a Windows Computer with Eclipse and Maven and a oracle linux with weblogic in oracle virtual pc.

I already installed the JaCoCo Agent on the linux box and it is running inside weblogic.

When I get the measured data form the weblogic in the vbox with the jacoco:dump goal, the corresponding .exec file fills with data.

But: there is no code coverage for the integration tests.

If I run the tests in Eclipse and import data from tcpserver with Import Code Coverage, there is code coverage shown.

I don't understand, what runs wrong in maven-plugin, because as I see no difference in information between Eclipse and maven.

Any suggestions?

Any hints are welcome how to solve this issue in maven. I'd like to show the jacoco results in sonarqube once the problem with the maven plugin is solved.

Hi,

where do the deployed classes from the interation tests do come from?
Note that the class files under tests must be the exact same class file
than the class files used at report generation time.

If you can import the exec file successfully to Eclipse this means the
classes under test are from your Eclipse workspace. Maybe within the
Maven build you use different class files (compiled with javac and not
Eclipse).
