sh releng/run.sh gen-eclipse -d dest/eclipse works fine on the buildfarm, but not locally (both new-spoofax-plugin branch).

Locally it generates files in the wrong places:

dest/eclipse/Info.plist (should be inside Eclipse.app)
dest/eclipse/MacOS/eclipse (should be inside Eclipse.app)
dest/eclipse/Resources/Eclipse.icns (should be inside Eclipse.app)
dest/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini (should be in Eclipse.app/Contents/Eclipse and triggers an error)

(and many other files in the app)

Resulting in the following error:

Traceback (most recent call last):
  File "/Users/daco/spoofax-deploy/releng/src/main.py", line 6, in <module>
    MetaborgReleng.run()

    with open(iniLocation, "r") as iniFile:
FileNotFoundError: [Errno 2] No such file or directory: 'dest/eclipse/Eclipse.app/Contents/Eclipse/eclipse.ini'

Because files are in the wrong place the .app is not executable on mac.

Try to delete ~/.spoofax-releng-eclipsegen and run eclipsegen again, think this is a caching issue.

Yes, that did the trick!
