If you want to run on JDK 11 you will need to make sure you have a
reasonably recent scala version installed. These work: 2.11.12, 2.12.11
and of course 2.13.2. It wouldn't hurt to use a recent sbt version as well.
Kind regards,
Erik.

I experienced this as well on Xubuntu 20.04 where I had JDK 11 installed. I
found this and was able to install JDK 8 and switch to it:

sbt runs and code compiles now
