This isn't exactly a bug report yet, but I seem to be getting some weirdness with my static assets on a Play 2.4 app when running in Dev mode. One specific CSS asset isn't working in Dev, but is in live:


Other CSS assets, like this one, work in both environments:


This was working on a week or so ago when I had an earlier RC version of Play 2.4.


Apologies for the lack of detail, will investigate further when I get the chance.

You don't have a lib/octicons folder in your project, it looks like.

The octicons are brought in by a webjar:

...and I guess it would be possible for me to be using the wrong path for where the library dumps the file down - but then why would it work in Live, and not Dev?

Ah, it's a webjar.  That makes sense. Did you deploy your assets?

You should be running "assets" or "web-pipeline" and then you'll see it in target/web/public/main/lib/octicons.  Then the URL is:


So there's an extra octicons in there.

Hey, that extra 'octicons' does get things working on localhost. What's kind of surprising to me, though, is that both paths return a CSS response in production:

...though they are different sizes, so I guess one corresponds to an older version of the CSS. It's like there's a CDN or caching proxy between me and the app, though I'm not aware of one. I don't think Heroku is doing that for me...

In any case, this seems more like a quirk of my hosting setup or connection, so not a problem with Play 2.4.
