Different errors during 'sbt' and 'sbt run' in scalafx-ensemble

Question

I downloaded the scalafx-ensemble project. When I run sbt in the project's folder I'm facing the following error:

[info] Set current project to scalafxEnsemble (in build file:/C:/dev/sample/scalafx-ensemble-master/)
[ERROR] Terminal initialization failed; falling back to unsupported

If I run sbt run I'm getting the following:

What am I doing wrong?

This is likely problem with outdated SBT launcher. Make sure that your SBT is v.0.13 or newer.

Thanks. I've solved this problem. It was a wrong path. In my system JAVA_HOME is 'C:\Program Files\Java\jre7' like a standard path of Java windows installer. In 'build.sbt' path to 'jfxrt.jar' is '%JAVA_HOME%+jre/lib/jfxrt.jar' and it's wrong in my environment. – falcon Jan 08 '14 at 07:24
Sorry. You were right. SBT version it was a one of a problems. – falcon Jan 08 '14 at 16:18

I fixed the path to jfxrt.jar in build.sbt from

System.getenv("JAVA_HOME") + "jre/lib/jfxrt.jar"

to

System.getenv("JAVA_HOME") + "/lib/jfxrt.jar"

which is correct for my system. With the change, sbt run works fine.

What about the error `IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected`? Did that go away, too?! [It looks the project uses 0.13.1](https://github.com/scalafx/scalafx-ensemble/blob/master/project/build.properties). – Jacek Laskowski Jan 07 '14 at 22:23
No. only 'sbt run' work fine. If i try to run 'sbt' i still get errors . – falcon Jan 08 '14 at 14:58
Sorry. I was a little bit confused by SBT versions. I've removed old SBT 1.12.1 and install latest version 1.13.1 which is defined in build. Finally all work fine. Thanks! – falcon Jan 08 '14 at 16:11
It means that the solution is a combination of your and @Jarek's answers, isn't it? You had to use the proper version of SBT and change the path to `jfxrt.jar`. Correct? – Jacek Laskowski Jan 08 '14 at 22:15
