I am new to scala and sbt, and I want to run the sbt command, but I get a Nullpointer exception, I don’t know why.
I have scala installed on the system:
scala - version of scala code version 2.11.8 - Copyright 2002-2016, LAMP / EPFL
Also, if I try to verify that the sbt version works fine:
sbt --version sbt launcher version 0.13.5
But when I just run sbt, I get an exception:

Any idea how to fix this?
