And then:

org.junit.platform.suite.engine.NoTestsDiscoveredException: Suite [mypackage.AllTests] did not discover any tests

Attached is a simple test project. Run with mvn clean verify

I did not face this issue yet (because I do not like to use @SelectPackages). From having taken a quick look into it (and currently no plans to further analyze it), I have some pointers:

• As can be seen in the log, during the Tycho build the package is referenced via a bundleresource URI. When executing the same tests from within Eclipse, a file URI is used.
• There have already been discussions on the support for bundleresource URIs, e.g.: https://bugs.eclipse.org/bugs/show_bug.cgi?id=570590
