NoSuchMethodError: org.junit.platform.commons.util.ReflectionUtils.tryToLoadClass
I changed the version of jupiter and junit to 5.3.2 and the problem has gone
I was able to run the Junit 5 tests after adding the platform and launcher dependency:
<!-- https://mvnrepository.com/artifact/org.junit.platform/junit-platform-commons -->
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-commons</artifactId>
<version>1.4.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.junit.platform/junit-platform-launcher -->
<dependency>
<groupId>org.junit.platform</groupId>
<artifactId>junit-platform-launcher</artifactId>
<version>1.4.0</version>
<scope>test</scope>
</dependency>
minimal required pom.xml setup for spring-boot 2.1.3 and junit 5.4.0 testing next:
