NoClassDefError with JUnit Jupiter 5.7.0

Hi, I want to use 0.9.1 JUnit Pioneer’s @org.junitpioneer.jupiter.SetSystemProperty but it currently fails with JUnit Jupiter 5.7.0:

It does not fail with JUnit Jupiter 5.6.2.

@fbiville I think you can fix this by adding junit-bom to your project. While it’s briefly mentioned in https://junit.org/junit5/docs/current/user-guide/#dependency-metadata-junit-bom in neither the case of Maven or Gradle does it tell you how to actually do it. Add to your pom.xml and let us know if it fixes the issue for you:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.junit</groupId>
            <artifactId>junit-bom</artifactId>
            <version>5.7.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

I have created #346. While, not a necessary change, it is probably safer to do so that the versions of jupiter and platform are automatically aligned for all possible dependencies.
