Proguard GUI doesn't start

I tried starting the proguard GUI with java -jar .\proguardgui.jar, but it fails with

Internal problem starting the ProGuard GUI (Can't find resource for bundle java.util.PropertyResourceBundle, key field_generalization_classTip)
java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key field_generalization_classTip

Did I set thing up incorrectly?

Hi @Martijn_Hoekstra

This seems to be an oversight in 7.1.0-beta2 - new optimizations were added but the GUI wasn’t updated. Can you try beta1?



Building 7.1.0-beta1 works as expected. I only now see there is a download for binaries on the github page. That would probably have been even easier.

Update: we’ve fixed this on the master branch now, so you can build from source again if you like! :slight_smile:
