MVC Bundling/Minification Failure for Kendo JS/CSS

[Ed]

I am getting Minification failed errors when trying to bundle together Kendo CSS & JS (separately in ScriptBundle & StyleBundle).  Here is the bundle code from BundleConfig.cs:

bundles.Add(new ScriptBundle("~/Scripts/kendo/responsive-kendojs")
                .Include("~/Scripts/kendo/jquery.min.js")
                .Include("~/Scripts/kendo/kendo.all.min.js")
                .Include("~/Scripts/kendo/kendo.aspnetmvc.min.js"));

and

bundles.Add(new StyleBundle("~/Content/kendo/responsive-kendocss")
                .Include("~/Content/kendo/kendo.common.min.css")
                .Include("~/Content/kendo/kendo.common-bootstrap.min.css")
                .Include("~/Content/kendo/kendo.bootstrap.min.css")
                .Include("~/Content/kendo/kendo.mobile.all.min.css")
                .Include("~/Content/kendo/kendo.dataviz.min.css")
                .Include("~/Content/kendo/kendo.dataviz.bootstrap.min.css"));

When I load my page, the bundles come across properly, but when I inspect the contents of the bundles, I see this content:

for request:
http://localhost:2952/Scripts/kendo/responsive-kendojs?v=xBcra9G7ySZaZKhcyL_pQa3jyJ0xPNrIODFoRbbwXqA1

I am currently using v2014.2.716 and VS2010 and MVC4.

Please let me know if you need additional info.

Hello Ed,

Thanks for the heads up. We'll investigate this issue and try to work around it.
Note that having a break statement outside of a loop is valid JavaScript. It's just that the ASP.NET minification doesn't like it.

My suggestion is to leave it as is, as excluding kendo.web.js requires ordering the scripts manually.

My apologies for the inconvenience.

Kind Regards,
