Hope it is not too silly to ask for an explanation here: I have this class: package asdfasdf; import org.junit.jupiter.api.Test; public class BetaTest { @Test void test() { // fail("Not yet implemented"); } } And the project does *not* contain the usual junit Library dependency e.g. what the quickfix adds. Instead I have converted the project to a maven project and have the following pom file: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>asdfasdf</groupId> <artifactId>asdfasdf</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api --> <dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter-api</artifactId> <version>5.7.0</version> <scope>test</scope> <exclusions> <exclusion> <groupId>org.opentest4j</groupId> <artifactId>opentest4j</artifactId> </exclusion> <exclusion> <groupId>org.apiguardian</groupId> <artifactId>apiguardian-api</artifactId> </exclusion> </exclusions> </dependency> </dependencies> </project> Run as->Maven test works fine: SLF4J: Class path contains multiple SLF4J bindings.

It cannot find its own opentest4j dependency in the class JUnit5TestListener. Is this expected?
Adding Mickael to comment if he has any idea on this.
To be honest, I'm more surprised that such exclusion manages to make the test pass with Maven. IMO, when user explicitly excludes some dependencies, they shouldn't be available at all; JDT is more correct than Maven here to me.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
