Failure to run runFeatures

[delphyne]

When I attempt to run a simple project using the CukePlugin, I get a stacktrace with the following error:

Execution failed for task ':cukeGems'.
Cause: java.lang.AbstractMethodError: org.jruby.ext.JRubyPOSIXHandler.error(Lorg/jruby/ext/posix/POSIX$ERRORS;Ljava/lang/String;)V
Cause: org.jruby.ext.JRubyPOSIXHandler.error(Lorg/jruby/ext/posix/POSIX$ERRORS;Ljava/lang/String;)V

Sorry, I was expecting the ability to attach files to the issue...

Here's a link to the full (long) stacktrace and output from 'gradle -q --stacktrace runF' https://webspace.utexas.edu/carrbm1/pub/CukePlugin-stacktrace.txt

Here's the full project that is failing. I included the .gradle folder in case it is somehow indicative of what's wrong: https://webspace.utexas.edu/carrbm1/pub/exercise-1.tgz

and finally, here's the 'gradle -v' output:
