I have a couple js files that I can seem to get GruntJs to concat/minify properly.
If I do each individually they work fine.
If I combine separately then attempt to minify just the combined file it doesn't work either.
Here is the error:
Any ideas on how to fix this? Or maybe what is causing it?
There is currently a problem with GruntJs and the BOM I mentioned in the comment of Derick's answer.
You can find the issue here: https://github.com/cowboy/grunt/issues/218#issuecomment-6329807
In Visual Studio to manually remove the BOM
Open the file > File > Advanced Save Options > Set the encoding to "Unicode without signature" > "Ok" That should remove it.
