无法在Mac中加载Eclipse中的SWT库

When I tried to run a plug-in project as Eclipse Application, I get following error.

Then, I found out that the folder "/{HOME}/.swt/lib/macosx/x86_64" acctually is empty. I guess this is the reason, but I do not know how to reinstall SWT(I have googled a while though)

Eclipse Version: Oxygen.1a Release (4.7.1a) (64-bit)

Answer 1

The command line arguments:

-os win32 -ws win32

show that you are trying to run this as a Windows application - which isn't going to work on macOS

Check that the Arguments tab of the Run Configuration has something like:

-os ${target.os} -ws ${target.ws} -arch ${target.arch} -nl ${target.nl} 

in the program arguments and that the 'Environment' section of your current Target Platform is blank or specifies macOS.
