When attempting to launch Eclipse-based app (ex: MyApp.app) on Mac, the following error is thrown:-
The 'MyApp' executable launcher was unable to locate
its companion shared library.
This problem seems to occur on macOS Sierra and later.
When unzipping the app, the lingering extended attributes prevent the app from launching.
To fix this, run the following command to remove these extended attributes:-
xattr -c MyApp.app
Then, double click MyApp.app to launch it.
