Bundling any ".min.js" file results in 404 #132

I'll work on getting an example repo but I wanted to go ahead and drop an issue while it's fresh on my mind. I went to update an older app and I noticed that my JS started to result in 404. After some debugging I noticed that if any js that was already minified was added via AddJavaScriptBundle it would cause the bundle to 404.

Ex. for existing min files. Jquery, Vue, Charts.js.

I have found that 3.0.250 does not have this issue. I have rolled back to that version for now. Hopefully I'll have some time free soon to do some further research.

Here are the libraries I'm using. It seems only the ".min.js" are causing the issues

"/lib/vue/vue.min.js", "/lib/vue-resource/vue-resource.min.js", "/js/vue-date.js", "/js/vue-progressbar.js", "/js/vue-resource-progressbar-interceptor.es5.js", "/js/vue-substring.js", "/js/vuelidate.min.js", "/js/validators.min.js", "/lib/jquery/jquery.min.js", "/js/jquery.FieldSelection.js", "/lib/underscore/underscore.js", "/js/chart.min.js", "/lib/signalr/signalr.min.js", "/lib/moment/moment.js", "/lib/toastr/toastr.min.js"

You may ask. Well Bob, if only the .min.js files are the problem then just reference the "non" min versions. Well some of the libraries do not have the non-minified version.

found the issue. Turns out your first file in the

pipeline.AddJavaScriptBundle( "/js/bundle.js", new CodeSettings { MinifyCode = false, }, "/js/empty.js", <- this first entry must not end with "min.js", if so then you'll always get a 404 "/lib/vue/vue.min.js", ...
