I use kotlintest in a Spring Boot Project for unit and integration testing. I can run my unit tests without any troubles in IntelliJ and all of them are green. When I run my tests in gradle with ./gradlew clean test
though, all my tests using the table()
, headers()
and row()
functions fail with the following exception:

All other tests are fine.
Here is part of my build.gradle

From what I read I shouldn't even need the io.kotlintest:kotlintest-assertions
dependency as it should be included in the runner.
It looks like TableTestingKt is not converted to a class, as it should be.
It all came down to the wrong Java Version - I had Java 11 set in IntelliJs settings but my JavaHome was pointing to a Java 10 which lead to this error.
