Unable to create directory.

uglify: {
            options: {
                mangle: false
            },
            my_target: {
                files: {
                    'publish/js/**/*.js': ['src/js/**/*.js']
                }
            }
        },

Throws me following errors:

Warning: Unable to create directory "c:\project\publish\js**" (Error code: ENOENT). Use --force to continue.

The destination doesn't work like that so you're getting an error because asterisk is not a valid character for files on windows.

If you are looking to uglify numerous files individually, you can look into building your files object dynamically, otherwise the destination should be a single file.
