java.lang.NoClassDefFoundError: org/junit/platform/commons/PreconditionViolationException when trying run junit5 test with maven

This error can be come due to the version mismatch of junit-plateform-engine junit-jupiter-params and junit-platform-runner and also other respective dependencies.

So for the resolution of this issue you do not need to define version like 1.5.3 ...etc

you can define version as follows :

    
        org.junit.jupiter
        junit-jupiter-params
        **${junit.jupiter.version}**
        test
    
    
        org.junit.jupiter
        junit-jupiter-engine
        **${junit.jupiter.version}**
        test
    
    
        org.junit.platform
        junit-platform-runner
        **${junit.platform.version}**
        test
    

So through this compatible version jar will be added in your project and project will run successfully
