Coverage generation minion exited abnormally! (UNKNOWN_ERROR) with v1.9.x and 1.10.x

[GerardSimon77]

I have the following error when I run Pitest on my micro services :

My PIT configuration is

  <groupId>org.pitest</groupId>
  <artifactId>pitest-maven</artifactId>
    <version>1.10.4</version>
    <dependencies>
        <dependency>
            <groupId>org.pitest</groupId>
            <artifactId>pitest-junit5-plugin</artifactId>
            <version>1.1.2</version>
        </dependency>
    </dependencies>

and I use junit 5.9.2

Pitest is configured in a library on which I have no problem. But this library is the base of all my micro services and the problem occurs on all of them. I've used PITest on versions 1.8.x without problem. This error appears when I try to upgrade the tool to version 1.9.x or 1.10.x (this trace is from version 1.10.4)

Seeing the same when switching to any version higher than 1.8.0:

@sothawo Pitest needs to be configured with a version of the junit 5 plugin that matches both the junit 5 version and the pitest version.

From the docs

    1.1.2 requires pitest 1.9.0 or above and JUnit Platform 1.9.2 (Jupiter 5.9.2)
    1.1.1 requires pitest 1.9.0 or above and JUnit Platform 1.9.1 (Jupiter 5.9.1)
    1.1.0 requires pitest 1.9.0 or above and JUnit Platform 1.9.1 (Jupiter 5.9.1)
    1.0.0 requires pitest 1.9.0 or above and JUnit Platform 1.8.x (Jupiter 5.8.0)
    0.16 requires pitest 1.4.0 or above and JUnit Platform 1.8.x (Jupiter 5.8.0)
    0.15 requires pitest 1.4.0 or above and JUnit Platform 1.8.x (Jupiter 5.8.0)
    0.5-0.14 requires pitest 1.4.0 or above and JUnit Platform 1.7.x (Jupiter 5.7.x)
    0.4 requires pitest 1.3.2 or above
    0.3 requires pitest 1.3.0 or 1.3.1
    0.2 requires pitest 1.2.5

Errors such as

JUnit5TestUnitFinder does not define or inherit an implementation of the resolved method 'abstract java.util.List findTestUnits(java.lang.Class, org.pitest.testapi.TestUnitExecutionListener)'

Indicate that the version of the plugin installed is not compatible with the version of pitest in use. If you have a multi module build, check that the versions are consistent in all modules.
