I generated a xtext grammar from an existing genmodel. When I tried to run the generated file an error occured. here is the error

    [main] ERROR mf.mwe2.launch.runtime.Mwe2Launcher  - java.util.zip.ZipException: error in opening zip file

Hi,

seems there is a broken zip/jar on your classpath. you can try to debug PathTraverser to find which it is.

Hi, thank you for your response!!!
I used the generated xtext code to implement a new project, and it works just fine.
I entend to generate ecore models from an existing script according to my grammar. I surveyed some tutorials which refer to the manipulation of the file Mydslgenerator.xtend in the package *.generator. Unfortunately, this package isn't generated after running the workflow. Do I miss something in the running process.
Best wishes

Hi,

is the generatorfragment contained in your workflow?
