Q:

sbt 0.13.0 JLine incompatibility detected

I have a problem with starting a play 2.2.0 app on my mac with mountain lion and java 7:
[ERROR] Terminal initialization failed; falling back to unsupported

Error during sbt execution: java.lang.IncompatibleClassChangeError: JLine incompatibility     detected.  Check that the sbt launcher is version 0.13.x or later.

It's not really linked to play since I got the same error when I start directly sbt in that directory.
So I tried a couple of things:

removed all sbt related stuff from my home dir and tried to use the sbt script from https://github.com/paulp/sbt-extras/blob/master/sbt -> same problem
removed all jars from my ivy repo dir and started again sbt -> same problem
downloaded a sbt launcher directly (version 0.13.0) -> same problem
tried with java 6 -> same problem
tried to debug sbt to figure out what's wrong but all I found out was that jline does not recognize that it should use a UnixTerminal (which I got working by setting systemProperties) but then again -> same error

It's somehow related to some strange linking I think because the class version for the terminal which should be used seems to be old. At least this is what the jvm is complaining about.
I tried it on a virtual box with ubuntu which worked fine so I think my system is a mess or I did something completely wrong.
Someone any ideas? 

A:

I had same problem. My project is using SBT 0.13
Turned out I need to upgrade SBT Launcher to 0.13 version as well.

A:

If you start the JVM with verbose class loading enabled (-verbose:class), that might help troubleshoot where the offending JLine classes are coming from. Perhaps you have a JLine jar in one of your JVM extension directories, probably ~/Library/Java/Extensions or /System/Library/Java/Extensions.
