Cannot create Launcher without at least one TestEngine when running tests

I'm trying to use your plugin to run pitest against some junit5 tests that I have but I'm having problems getting it to run... this may be something I'm doing incorrectly but I thought I'd reach out.

I've cloned and build your plugin locally on my machine, then after including it as a plugin dependency to pitest-maven, and attempting to run the goals:

mvn -U clean install
mvn org.pitest:pitest-maven:mutationCoverage

I can see that it can see the plugin from the output:

[INFO] --- pitest-maven:1.1.11:mutationCoverage (default-cli) @ junit5-pitest-tester ---
[INFO] Found plugin : Default csv report plugin
[INFO] Found plugin : Default xml report plugin
[INFO] Found plugin : Default html report plugin
[INFO] Found plugin : Default limit mutations plugin
[INFO] Found plugin : Kotlin junk mutations filter
[INFO] Found shared classpath plugin : Default mutation engine
[INFO] Found shared classpath plugin : JUnit 5 test framework support
[INFO] Adding org.pitest:pitest-junit5-plugin to SUT classpath
[INFO] Adding org.pitest:pitest to SUT classpath

However, I am getting an error shortly after that:

I have tried including a few of the junit-jupiter-xxx and junit-platform-xxx dependencies with the pitest-maven plugin (various combinations of these), but I can't seem to get it to work, it always gives the above problem. Perhaps I'm missing some other dependency?
