Landed at https://github.com/jquery/jquery/commit/b20f536748300d5aef31ad68cc5adff849a1ee13

Releases at code.jquery.com will have associated maps, and maps will be included in the packages released to other CDNs:

jquery-X.Y.Z.js
jquery-X.Y.Z.min.js
jquery-X.Y.Z.min.map

**NOTE: Renaming the uncompressed jquery-X.Y.Z.js file requires an edit to the jquery-X.Y.Z.min.map file to reference its new name or location.**

You may be aware but the current rc1 release of 1.9 tries to request code.jquery.com/dist/jquery.min.map in chrome dev tools which 404s.

Manually requesting http://code.jquery.com/jquery-1.9.0rc1.min.map works but the comment being generated by the build is wrong.

Thanks! Yes, the build process fixed the map file but I missed the comment.

Lazy bots.

Closed via https://github.com/jquery/jquery/commit/e348b4060848b46a6c4376661c093e0f0a3ef9e7 (1.9) and https://github.com/jquery/jquery/commit/2ff2d1d3dcd99f7bd45fa312ba91bb1248cb6d55 (2.0)

I am seeing inconsistent behavior in Chrome 23 Windows but think it's Chrome and not the map file.

Chrome Version 29 tries to load .../jquery.min.map 404 (Not Found)

I confirm that Chrome version 29 tries to load /jquery.min.map and fails. Also Chrome Canary...

The last two posters. What version of jQuery are you using? Did you rename the files?

Changed August 07, 2013 01:36PM UTC by Andrew comment:11

We see the same problem - request's for jquery.min.map (which 404) from:

Chrome 28.0.1500.95 (up to date as of today) and

jquery-2.0.3.min.js (downloaded fresh this morning - and not renamed or fiddled with in any way.

OSX Lion 10.7.5 (although hopefully that's irrelevant)

Interestingly, it requests the missing file at the same path as jquery. Ie, jquery is referenced at /somefolder/jquery-2.0.3.min.js and the missing file is requested at: /somefolder/jquery-2.0.3.min.map

This only happens if we have the chrome dev-tools open. (checked using an http debugger).

@Andrew, if you have "use sourcemaps" enabled in dev tools and did not copy the map file to the same location with the same name, then the map file is indeed missing.
