NoClassDefFoundError: com/google/common/collect/ImmutableList

did you run the initial setup? that class is in guava lib, which comes by default in MDK, so it should be there... do you see it in your IDE?

How did you set up the server? How are you starting it?

[FredM]

well, mainly running 'gradle build'... that's the task that should pull down all the lib dependencies ... more details https://mcforge.readthedocs.io/en/latest/gettingstarted/
