Unrecognized VM option 'CMSClassUnloadingEnabledn-J-Xmx2Gn'

I have installed scala, sbt on Mac. When I try to run sbt it gives an error Unrecognized VM option 'CMSClassUnloadingEnabledn-J-Xmx2Gn'. I think there is an issue with JVM but could not find any help for this error.

More error info: Did you mean '(+/-)CMSClassUnloadingEnabled'? Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

Solution

  • My guess is that the sbt configuration is confused with regards to line breaks and mangles something like

    -J-XX:+CMSClassUnloadingEnabled
-J-Xmx2G

    into one line
