Use checksums to notice modifications in files in JARs

[emezeske]

One problem that I have personally experienced, and have heard others complaining about, is the project not being rebuilt when an upstream JAR that contains CLJS code is updated. This is due to timestamps being used for noticing modifications, but JAR-ed files don't contain timestamps. So, lein-cljsbuild should keep track of checksums for those files, and use that to notice modifications.

Not clear on what this would be. Any CLJS code in upstream .jar files would be dependencies of your project, which the ClojureScript compiler would resolve, not cljsbuild.

Am I misunderstanding the intent here?

Whew, that's an old issue. Short of reconstructing my state of mind when I created it, I don't think we're going to ever understand what I was thinking. Your note on the dependencies makes sense to me, so I'll close this.
