Just created a fresh OH3 addon development environment with Eclipse installer, but when try to run/debug junit test directly from Eclipse I got following error.

Any ideas? OH itself run fine via app.bndrun.
Edited…
Not sure if this is correct fix, but junit tests seems to work fine when add Junit as library to build path.
Right click on project -> Build Path -> Add libraries…
Select JUnit from the list
Select JUnit5
