SBT 0.13.7 and Scala 2.11.5 version compatibility issues

Question

Trying out sbt version 0.13.7 with scala version 2.11.5. Both are the newest right now. Do they work together? When I run sbt clean compile, it prints:

[info] 'compiler-interface' not yet compiled for Scala 2.11.5. Compiling...
error: java.lang.NoClassDefFoundError: scala/tools/nsc/typechecker/Infer$Inferencer

When changed to scala 2.11.4, it is all ok:

[info] 'compiler-interface' not yet compiled for Scala 2.11.4. Compiling...
[info]   Compilation completed in 13.434 s

I could not find any relevant sources about sbt and scala version compatibility. Could it be related to Does sbt build against scala 2.11? ?

Answer 1

You could try to remove your local cache, sometimes this is in bad state in my experience:

rm -r ~/.sbt/boot/
rm -r ~/.ivy2/cache/org.scala-lang/
rm -r ~/.ivy2/cache/org.scala-sbt/

Answer 2

The following will be better

rm -rf ~/.sbt/boot/
rm -rf ~/.ivy2/cache/org.scala-lang/
rm -rf ~/.ivy2/cache/org.scala-sbt/

If this failed, run activator several times.
