Running JUnit 5 Suites with @SelectPackages

[drsgoodall]

I'm having trouble with JUnit 5 test suites using @SelectPackages in particular. I can run them fine in Eclipse, but not with Tycho (4.0.6).

I have a test suite such as this,

@Suite
@SelectPackages({"com.example"})
public class SuiteTests {
}

However running in Tycho will result in

WARNING: Error scanning files for URI bundleresource://11.fwk2141489356/com/example
java.nio.file.FileSystemNotFoundException: Provider "bundleresource" not installed
        at java.base/java.nio.file.Path.of(Path.java:212)
        at java.base/java.nio.file.Paths.get(Paths.java:98)
        at org.junit.platform.commons.util.CloseablePath.create(CloseablePath.java:58)

I've tried setting the Eclipse-BundleShape directive to dir, but this did not help.

I believe it might be the class loader - running in Eclipse Thread.currentThread().getContextClassLoader() is org.eclipse.pde.internal.junit.runtime.MultiBundleClassLoader whereas in Tycho it is class org.eclipse.tycho.surefire.osgibooter.CombinedClassLoader

Does anyone have any suggestions on getting this working?

Thanks

The best way always is to provide an integration-test to demonstrate the issue or at least a small example project. What I rember is that suites have had problems in the past so there is a good chance that @SelectPackages({"com.example"}) has similar issues.

Hopefully this repository will illustrate the problem

Run with mvn clean integration-test
