I'm trying to get project with the packaging type eclipse-test-plugin to work (I have the ambitious goal to get it to execute tests someday, but right now there are only two classes with empty tests methods inside).
I assume the problem only exists because we use a target configuration file, so needed plug-ins (or whatever) get not loaded automatically. In the absence of an up-to-date documentation or examples I guessed that the pom.xml for such a use case should look something like that:
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-junit4</artifactId>
<version>${see.below}</version>
</dependency>
</dependencies>
<build>
<sourceDirectory>src</sourceDirectory>
<plugins>
<plugin>
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-surefire-plugin</artifactId>
<version>0.22.0</version>
<configuration>
<providerHint>junit4</providerHint>
</configuration>
</plugin>
</plugins>
</build>
(Because without the dependency I got a ClassNotFoundException: org.apache.maven.surefire.junit4.JUnit4Provider, and that's where the class resides.)
Now if I use the version 2.18.1 or below of the surefire-junit4, I get the following error:
An error has occurred. See the log file C:\workspaces\workspace\org.acme.project.rxp-build\org.acme.project.rxp.it\target\work\data\.metadata\.log.
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:0.22.0:test (default-test) on project org.acme.project.rxp.it: An unexpected error occured while launching the test runtime (return code 13). See log for details. -> [Help 1]
Aaand the log file in question contains:

If I use version 2.19 of the surefire-junit4, I get the following message:

I was a bit suspicious that surefire-api and surefire-junit4 had the same version, so I made sure that Maven loads the same versions for both, but there was no change in the behavior.
What's the problem here? How do I get the test plug-in to build?
Okay, it works without stupid Maven dependencies if the target platform file contains
<unit id="org.hamcrest.core" version="0.0.0"/>
<unit id="org.junit" version="0.0.0"/>
<unit id="org.eclipse.jdt.junit.runtime" version="0.0.0"/>
<unit id="org.eclipse.jdt.junit4.runtime" version="0.0.0"/>
and the Manifest.MF contains
Require-Bundle: org.eclipse.jdt.junit4.runtime,
org.junit
