I wanted to use maven-plugin-testing-harness and I am including the following dependency into my project:

<dependency>
        <groupId>org.apache.maven.plugin-testing</groupId>
        <artifactId>maven-plugin-testing-harness</artifactId>
        <version>3.3.0</version>
        <scope>test</scope>
    </dependency>

I am getting the following error:

How do we fix this?

Including the org.eclipse.sisu plexus dependency before the testing-harness causes the correct DefaultPlexusContainer class to be loaded by the class loader.

 <dependency>
            <groupId>org.eclipse.sisu</groupId>
            <artifactId>org.eclipse.sisu.plexus</artifactId>
            <version>0.3.3</version>
        </dependency>

        <dependency>
            <groupId>org.apache.maven.plugin-testing</groupId>
            <artifactId>maven-plugin-testing-harness</artifactId>
            <version>3.3.0</version>
            <scope>test</scope>
        </dependency>

This seems to work. The order of the dependencies is important.
