Compile error on latest boot-cljs 0.0-2629-9

[pithyless]

Works:

[adzerk/boot-cljs      "0.0-2629-8" :scope "test"]
[cljsjs/boot-cljsjs    "0.4.1"      :scope "test"]

Broken:

[adzerk/boot-cljs      "0.0-2629-9" :scope "test"]
[cljsjs/boot-cljsjs    "0.4.1"      :scope "test"]

Is this an issue with boot-cljs or boot-cljsjs?

Oh. That's bad and most likely my fault. Changed something in boot-cljs with https://github.com/adzerk/boot-cljs/pull/39. I think I know where the error is and will fix it.

[martinklepsch]

@pithyless Ok, I thought I new where the error is but I can't reproduce it here. Is there a chance you could put the project where this occurred on Github?

[pithyless]

@martinklepsch I narrowed it down to adding just [cljsjs/react "0.12.2-3"] to build.boot:

https://github.com/pithyless/boot-cljs-bug

[martinklepsch]

@pithyless thank you, that was very very helpful! I pushed a fix here: https://github.com/martinklepsch/boot-cljs.

If you clone that and run boot build-jar inside the cloned directory it will be installed to your local Maven repo and you should be able to run boot dev in the project you provided as a testcase.

[martinklepsch]

If you could report back here that the problem is gone, that would also be helpful. @nblumoe I think this will also fix the problem you're having.

[martinklepsch]

Oh, and @pithyless you should probably update your App Version of Boot to RC8, the binary that you you're using (RC4) is outdated (I'm surprised it works actually :))

[pithyless]

1. This fixed the issue; thanks @martinklepsch for the quick response!
2. I learned how to build a local version of a library I need to depend on. I was looking for this earlier and I couldn't figure it out; we need to push this into some FAQ in the wiki :)
3. It's also non-obvious that boot -u did not update the binary. I had not realized until today when trying to document the issue.

Thanks again!

I learned how to build a local version of a library I need to depend on. I was looking for this earlier and I couldn't figure it out; we need to push this into some FAQ in the wiki :)

Maybe that's something that could be added to the "Boot for Leiningen users" page: https://github.com/boot-clj/boot/wiki/Boot-for-Leiningen-Users

It's also non-obvious that boot -u did not update the binary. I had not realized until today when trying to document the issue.

Have you read this? https://github.com/boot-clj/boot/wiki/Keeping-Boot-Up-to-Date If you did, feel invited to edit it to make that differentiation more clear.

This almost resolves my issue, as it's working now. However, the path isn't correct though:

TBH I don't understand yet WHY this is working, as react.inc.js is present only in target/js, not in the root folder. But still the web server serves it from localhost:3000/react.inc.js

[nblumoe]

Serving the build artifacts from a copy of /target (to prevent loosing it's contents when running boot) via boot serve -d <TARGET-COPY> wait does not work (404 for localhost:3000/react.inc.js). So, somehow boot build makes the file available from the web server's root. Is this related to filesets maybe?

[martinklepsch]

@nblumoe to be honest I'm not sure what's going on there. We're in the middle of migrating this kind of stuff to use :foreign-libs as it is provided in the latest version of Clojurescript so these features are likely to be removed from boot-cljs anyways.
