Gitlab-Runner Mvn Test Issue

Hello Everyone,
I m quiet new to Gitlab and GItlab-Runner
Its an awesome set of tools.
Lately I am facing one odd issue while building my code with Maven.
I was able to build my code perfectly fine some days back and for the past few days GitLab-Runner is giving me issues. Odd thing is there is nothing that changed with my code. I tried a lot of different tricks but now I am running out of ideas.
Its a Mulesoft (ESB) code that I am trying to build using Maven in Gitlab-Runner and it consistently gives me warning of Error: Could not find or load main class org.mule.munit.remote.RemoteRunner.
Same code compiles and builds fine when I try to mavenise from my local machine.
I am not sure if I need to reset anything again, clear cache or some setting change… if anyone can give me some direction over this it would be very helpful.
Below is the attached log trace.

Did you ever manage to get an answer for this one? I would really appreciate it.

Please check if you are using jre or jdk. Maybe it is because of that.

Seems Mule MUnit does not work with OpenJDK 8u181 which is the version in the default maven docker image. Switching to maven:3.6-jdk-8-alpine (which has u191) seems to have solved the problem for me.
