jython -m broken for scripts inside jar files

The workaround jython -c "import module; module.blah()" will work, but not if you don't have a blah function.

This is jy.bat


Version 2.5.2

Looking at the source it seems that ClasspathPyImporter is indeed lacking this method.


No such module is a different, correct error:

Still present under the latest beta release

This is jy.bat just to show there is nothing weird there. Jython 2.5.2 was the version disted with the robot framework.

rem set JYTHON=%M2_REPO%\org\robotframework\robotframework\2.7.1\robotframework-
2.7.1.jar
set JYTHON=C:\Working\tools\jython\jython2.5.3b1\jython.jar


java -classpath %JYTHON%;%M2_REPO%\ets\tools-core\1.3.1-SNAPSHOT\tools-core-1.3.
