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

I'm using:

Spring Tool Suite 4 Version: 4.4.2.RELEASE Build Id: 201911201053 Java version: 1.8.0_191

and the message displayed is No tests found with test runner 'JUnit5'

what worked for me was the configuration below

    
        1.8
        5.5.2
        1.5.2
     

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