Warning: Uglification failed. Unexpected token: eof (undefined)

Question

I use uglify with grunt, and for some reason it throws a warning on my app file:

Warning: Uglification failed. Unexpected token: eof (undefined). Line 15472 in dist/app.annotated.js Use --force to continue.

This is the file with lines:

15469   $scope.selectLocation = function () {
15470       $("#locationIframe").html('');
15471       if (($scope.LeadObj.address1 == "" || $scope.LeadObj.address1 == null) && $scope.LeadObj.ip != null) {
15472           $scope.showLocation = 'loading';
15473           $.ajax({
15474               type: 'GET',

Besides the fact that this code is stupid, why do I get this warning? it all checks out..

Answer 1

As suggested in the comments, the problem was with how the lines ended. Not all of them ended in the UNIX style of \n.

The solution was to use grunt-lineending to convert the file to use correct line endings before uglifying.

lineending: {
    dist: {
        options: {
            overwrite: true,
            eol: 'lf'
        },
        files: {
            '': ['dist/**/*.js']
        }
    }
},
