Hi @AndreyUL

The error would suggest that the issue is before hitting 'Weave Events to DLL' at the stage of generating GUI for that editor. Is that the case?

If so perhaps Unity can not access Pligin Executable Path for whatever reason (can see that's empty) - you might want to either debug why that's the case or perhaps picking manually would help.

If it happened at after clicking the 'Weave Events to DLL' button then we'd need to look at the error that comes from command line tool (that repo is just a wrapper around it and real issue will be in console app).

You can place a breakpoint or Debug.Log in Assets.MissingUnityEvents.Editor.EventILWeaverCommandLineArgsGenerator.GenerateAddEventsCommandLineArgs and then try to re-weave - this will give you command line tool that's executed, with that probably easiest to just run it from command line and see what's happening.

Maybe it picked up some wrong input files as -t parameter.

If that still doesn't bring you closer to a solution you can pull source code for actual command line tool that does the work
https://github.com/handzlikchris/AddingEventsToCompiled3rdPartyLibrary then run debug on that with your parameters - that should give you better idea what's happening.

Hope that helps,
Chris

The exception is thrown by DirectoryInfo.GetFiles method in EventILWeaverCommandLineArgsGenerator.GetUnityRequiredDllPaths(). This is related to file paths that are too long.

Great - thanks for letting me know, I'll close the issue.

@AndreyUL I'm facing the exact same issue, and Ican't really move the path it's looking for to a shorter path since it's just unity files, and i can't find a solution. i tried enabling long path support on windows but that didn't help, how did you get around this problem?

the path my editor is trying to access is C:\Program Files\Unity\Hub\Editor\2020.2.7f1\Editor\Data\PlaybackEngines\AndroidPlayer\NDK\sources\cxx-stl\llvm-libc++\test\std\experimental\utilities\propagate_const\propagate_const.nonmembers\propagate_const.comparison_function_objects and that directory does exist
