I'm working on creating a pom for a project and adding test cases to it. The project is an eclipse plugin.
Compiling the project with tycho works just fine, the only problem is during testing: If I run both maven-surefire-plugin tests and tycho-surefire-plugin-tests, the former performs all the tests as expected, while the latter gives the following error:
Execution test of goal org.eclipse.tycho:tycho-surefire-plugin:1.7.0:test failed: Tycho build extension not configured for MavenProject
I would be perfectly fine to just add <skipTests>true</skipTests>
to the tycho-surefire-plugin while keeping maven-surefire-plugin on; the problem is even that way, jacoco refuses to create the coverage site, with the following (non error) message:
Skipping JaCoCo execution due to missing execution data file.
I tried to look for solutions of both, but any combination of the solutions I found doesn't lead me to having a working coverage site. Maven really makes me quite confused, especially with tycho around, so I'd apreciate any explanation on top of the actual fix.
Here is my pom:

Of course there won't be any test result for the JaCoCo due to you are using very old Surefire version
2.12.4
. This version was not created for JUnit5. Use the latest version3.0.0-M5
and see the tutorial.If you want to have tiny POM, remove the dependency
junit-jupiter-engine
due to you do not need to have an access to the JUnit internals in your test code. The Surefire will download it shortly before the test runtime.
