Bundling and Minification finding wrong file

Question

So I'm having trouble all of a sudden where when I do my bundling and minification it pulls up the wrong file version.

bundles.Add(new ScriptBundle("~/bundles/jquery").Include("~/Scripts/jquery-{version}.js"));

bundles.Add(new ScriptBundle("~/bundles/scripts").Include(
                             "~/Scripts/bootstrap.js",
                             "~/Scripts/knockout-{version}.js",
                             "~/Scripts/jquery.signalR-{version}.js",
                             "~/Scripts/underscore.js",
                             "~/Scripts/Code/vLib.js"
                             ));

bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                             "~/Scripts/jquery-ui-{version}.js"));

The files that I have in my solution are: jquery-1.8.3.js, jquery-ui-1.9.2.js, knockout-2.2.0.js, jquery.signalR-0.5.3.js.

The files that the website is looking for when I deploy are: jquery-1.7.2.js, jquery-ui-1.8.22.js, knockout-2.1.0.js, jquery.signalR-0.5.2.js.

My understanding is that when you use the version, it will look for the newest version....but I guess something is messed up.

Anyone have any thoughts?

Answer 1

It does not use the latest but is there so that you do not have to recompile if you update jquery to the latest. I believe it looks for the first file that meets the requirements.

The {version} pattern is just a regex basically, so it will match and include all versions of jquery currently. We will definitely consider adding something like {highest-version} in the future.
