PlayFramework 2.3.1 NoClassDefFoundError: org/fusesource/jansi/AnsiOutputStream - scala

Question

I'm studying Play Framework 2.x and I have installed the framework, with the activator 1.2.3, on my Fedora FC20. Now I'm facing a strange error on launching the activator new, that never happened before. I've tried with java-1.7.0-openjdk-1.7.0.65-2.5.1.2.fc20.i386 and also with openjedk 1.8.0, but this error is still here.

Answer 1

You can try to delete and recreate your local repo (not quite sure which one applies to you):
~/.m2/repository
~/.ivy2/cache
~/.ivy/cache
Also, there was a play clean command before they switched to the activator. There should be something like activator clean now. After this you can try with activator compile.
Edit: as #sentenza pointed out, removing ~/.sbt was the correct step which solved the problem. I will still leave the other options above as they might work for somebody else.
