Duplicate namespaces in .jar

[MrEbbinghaus]

In the jar of hasch there is the folder: /private/js/out which contains duplicates of clojure, cljs, incognito and hasch namespaces. This results in a ton of warnings when compiling with shadow-cljs and (in my case) results in errors later on.

Looks like this:

I have removed them manually in 0.3.7. I need to bump some deps in the near future, but I got blocked with my current attempt by cognitect/transit-java#31. If you hit other issues, please open another ticket.

FYI, ran into this as well building an ueberjar using seancorfield/depstar, which emitted a whole load of clashing jar item warnings, e.g:

{:warning "clashing jar item", :path "public/js/out/cljs/pprint.cljs.cache.edn", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/reader.cljs.cache.edn", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/pprint.cljs", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/repl.cljs.cache.edn", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/repl.js", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/core.js", :strategy :noop}
{:warning "clashing jar item", :path "public/js/out/cljs/pprint.js.map", :strategy :noop}

Manually bumping hasch to 0.3.7 fixed it.
