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?

Answer 1

This is likely problem with outdated SBT launcher.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

Answer 2

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.
