sbt fails with java.lang.NoClassDefFoundError: sbt/ConsoleOut$

After using sbt for some time, something failed and I can't run sbt on my Ubuntu machine. I get this exception no matter what I do. Even running sbt help causes the following error:

Error during sbt execution: java.lang.NoClassDefFoundError: sbt/ConsoleOut$

I reinstalled the JDK and of course sbt, but it didn't help. The only thing I remember doing was installing the new IntelliJ IDEA 13. Could this be related?

Alternatively, it could be that your project uses a too old version of sbt, somehow breaking some dependencies. Update sbt.version in project/build.properties and it should work again.

In windows, log with cygwin or any other terminal emulator and run below commands:

  1. rm -rf ~/.sbt
  2. rm -rf ~/.ivy2
  3. rm -rf ~/.ivy

Most probably this issue comes from the IntelliJ IDE, Close all the running processes of the IDE and start it again.

In sbt:

clean

Results in re-resolution of ivy artifacts on next compile, without having to clear the ivy cache.

If the ivy itself is the problem then above solution is a good fallback.

It could be related.

Try:

rm -rf ~/.ivy/cache
mv ~/.sbt ~/.sbt.old
