Pomless unittest fails (version 5.0.1)

[aktion-hip]

I have set up my Eclipse RCP project with Tycho pomless directory layout (using Tycho 5.0.1). Therefore, I have structured my bundles according to the suggested convention (i.e. bundles/, tests/ etc.). In the root's pom.xml, I have the modules section accordingly:

    <modules>
		<module>target-platform/</module>
		<module>bundles/</module>
        <module>tests/</module>
        <module>features/</module>
    </modules>

In this pom.xml, I have configured tycho-maven-plugin, tycho-versions-plugin, target-platform-configuration and tycho-source-plugin.
Running mvn clean verify, I see a reactor summery that looks okay. However, the maven run fails when running the test fragment:
[INFO] [test-bundle] Test fragment for SWC Core 1.0.0-SNAPSHOT FAILURE [ 1.098 s]
The error message is as follows:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:5.0.1:test (default-test) on project ch.ethz.id.sws.swc.core.test: Execution default-test of goal org.eclipse.tycho:tycho-surefire-plugin:5.0.1:test failed: Cannot resolve dependencies of MavenProject: ch.ethz.id.sws.swc.core.project:ch.ethz.id.sws.swc.core.test:1.0.0-SNAPSHOT @ C:\Users\lbenno\git\SWC\core\ch.ethz.id.sws.swc.core.project\tests\ch.ethz.id.sws.swc.core.test\.tycho-consumer-pom.xml

What do I need to do to ensure that the tests (fragment bundles) can be carried out successfully?

[laeubi]

Can you run with -e to see if any exception is printed?

[laeubi]

I would assume that some kind of resolution error is then printed somewhere (but of course hard to guess without an example)

[aktion-hip]

I see. So you think, the following is the culprit:

[ERROR] Cannot resolve project dependencies:
[ERROR]   You requested to install 'java.package; org.junit.platform.suite.api [1.0.0,2.0.0)' but it could not be found

[laeubi]

Yes, you should check if your test is maybe requesting an incompatible range (or no range at all).

[aktion-hip]

I had to add junit-platform-suite-api, junit-platform-suite-commons and junit-platform-suite-engine to my target platform. Now, the mvn verify runs as expected.
Thank you for your hints and the immediate help,
Benno
