@plexus merged your first patch, the second looks good, but there are some conflicts. Rebasing from master should fix things, and I’ll be able to merge the last pr

@richiardiandrea is GWT that good?!

@richiardiandrea I just peaked through the source of aether, seems like the primitive "artifact" has a direct dependency on java.io.File. Which (a cursory look) seems to be depended on by the code I saw for classpath arithmetic. A quick google says java.io.File is not supported in gwt (makes sense!). Is this a blocker to compiling aether with GWT?

Having said that… http://www.jsweet.org/faq/ > Package http://java.io: requires the J4TS candy to support some Java IO styles and a local-storage-based FS (beta). So, maybe it could work with jsweet?

made a thing with lumo :slightly_smiling_face: https://www.npmjs.com/package/synaesthetic

@dominicm GWT is used to cross compile the the google closure compiler to the googole-closure-js compiler, presumably if it can handle that project it should be able to handle maven

That's awesome. Right, somebody needs encouraging to dedicate their life to that :thinking_face: Any takers? :grinning:

I have been looking at other alternatives as well something like this https://github.com/konsoletyper/teavm maybe

@dominicm we were checking with @stbgz here some time ago if it was any good, I have never tried it but heard good things...probably needs some refinement after the conversion but still...an attempt can be made :smile:

@plexus commit merged!, also sweet project by the way

are there any known issues with source map support when using the compiler API?

;; BOOM

probably :disappointed:

the build API is a very rough draft of what it might become one day

lots of stuff missing

I haven’t put any work into source maps yet

ok, good to know. I'll leave that part out then :slightly_smiling_face:

@plexus feel free to open issues for all the rough edges you find

makes it easier not to forget those problems exist

ok... it's not really a minimal example, but I can make a gist of what I have so people can try to reproduce it

will file an issue
