I had an already working JUnit4 Selenium test enviroment. After I switched from Java 8 to 11 eclipse doesn't always find my tests anymore. I can fix it eventually, but it always takes time. Can you help me fix it?

Every test has an @Test Annotation and the test project worked for years without those problems. My Folder structure is like:

ProjectName/src/test/java/testPackage/testClass.java

If eclipse doesn't find the tests I'm using the following options which seem all sometimes to work and sometimes not:

restarting Eclipse
rebuilding project
renaming some test with a prefix "test" ~ I know, crazy.
reloading all test files in eclipse [F5]
changing the Run Configuraion source folder to src/test/java.

All those "solutions" aren't always helping and I have to try around to find the one that helps. But I can fix it eventually.

Does anyone have a solution that always fixes that kind of problem? Or even better, is there a solution to fix it permanently?

Can you share us more informations like your runner classes? – sayhan Oct 08 '19 at 10:15
I didn't specify any runner class, so I'm using the JUnit4 default runner. – Joshua Link Oct 08 '19 at 10:24
Is your features are defined under RunCukes or your current runner? – sayhan Oct 08 '19 at 10:25
I don't use RunCukes. I just use ProjectName->run as->JUnit Test with my JUnit4. And with Java 8 it never had any problems. With Java 11 it does somehow. I didn't change the eclipse version [2018-12 (4.10.0)] – Joshua Link Oct 08 '19 at 10:57
Sorry Joshua I thought it was about cucumber. – sayhan Oct 08 '19 at 11:19
Do you have main method inside of your test classes? – sayhan Oct 08 '19 at 11:21
No I don't have a main method – Joshua Link Oct 08 '19 at 11:22
Your Eclipse is outdated, you are 3 releases behind. Can you reproduce the issue with the [current Eclipse version 2019-09 (4.13)](https://stackoverflow.com/a/53964503/6505250)? – howlger Oct 08 '19 at 11:49
I will try it tomorrow, thanks for your help already. – Joshua Link Oct 08 '19 at 11:52
