Eclipse No tests found using JUnit 5 caused by NoClassDefFoundError for LauncherFactory

Question

The problem

Whenever I run my projects JUnit test (using JUnit 5 with Java 9 and Eclipse Oxygen 1.a) I encounter the problem that eclipse can\'t find any tests.

Answer 1

As everyone informed it's IDE bug, I tried in Eclipse and STS. In both the cases, it is failing.

As a workaround, I have fixed by modifying the pom.xml file like below.

I have added these two maven dependencies junit-jupiter-engine and junit-platform-launcher.

pom.xml

    
        org.junit.jupiter
        junit-jupiter-engine
        ${junit-jupiter.version}
        test
    

    
    
        org.junit.platform
        junit-platform-launcher
        ${junit-platform.version}
        test
    

Also please make sure to add the version of both the maven dependencies in the properties tag.

    1.8
    5.2.0
    1.2.0
