I am using a surefire dependency like below. Do I have to add anything in the plugin dependency for running tests in parallel using Junit5?
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>3.1.2</version> </plugin> I will see if I can reproduce it in a small project. In the meantime, if I can share some debug logs from surefire which can help in debugging the issue let me know, and I can do that. Also, if there are any open issues related to this in Surefire, can you please share its link so that I can track them on my end?
