Getting a NullPointerException if sbt-launch.jar is not executable

    • CentOS 6.5
      sbt 0.13.2 (installed as RPM)
      Jenkins 1.560
      sbt plugin 1.4

      See the stacktrace below if sbt-launch.jar is not executable. I upgraded to SBT 0.13.2 installing it RPM and it so happens that the jar is only "a+r".
      Once I did a "chmod a+x sbt-launch.jar" the NPE did not happen anymore.

          The new location is actually /usr/share/sbt-launcher-packaging/bin for sbt launcher version 0.13.5. chmod a+r /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar is not required since it's already set, but you still get:
