This has always been an issue for me, but I'm just finding out today that it might not be an issue for anyone else. Anytime I try to view kotlin source code (in this case kotlinx-serialization) I always just get "compiled code" stuff like this. Clicking the download sources button, attaching sources, etc, doesn't do anything. Does anyone else have this issue as well?

Is this in an environment with a proxy or custom SSL certificates (e.g. work laptop)? I have this issue all the time from my work laptop. I don't know if I've ever had it on my personal laptop.

it is a work laptop. I haven't tested from my personal. I'm not sure if there are custom ssl certs, and I have all proxies turned off.

Our environment has both a HTTP proxy that all outbound traffic is required to go through, and custom SSL certificates (from the proxy). To get IntelliJ working, I had to configure the proxy settings in Settings > Plugins > Http Proxy Settings, and import the custom certificates into IntelliJ's truststore.

alright. I'll try that out thanks!

It may just be a side-effect of the macOS development ecosystem. Every time homebrew upgrades a package, or the Jetbrains toolbox upgrades an application, it blows away any existing truststore and I have to re-import the certificates.

hm... haha how'd you know it was a mac I'm using?

Why would it fail to work if I literally Attach Sources though?

I have no idea. All I know is that there have been times where I've had the -sources.jar, clicked attach, and it still doesn't work.

yeah that's exactly what is failing for me too...

😉 (I was referring to my experience. I also happen to use a Mac.)

haha.

Anyway, I'm sure there's an existing issue about this in YouTrack. I'll see if I can find something. If not, might be worth reporting. https://youtrack.jetbrains.com/issues/IDEA

I had searched and all I could find was just "turn on download sources in the settings", which is obvious, and also not the issue.

Was it this one? https://youtrack.jetbrains.com/issue/IDEA-247523

I had seen that one, but didn't click in as I don't have any sort of failures in the build tab and I haven't checked the logs yet. I just always (for years now actually) thought it was just not finding any sources and never questioned it. But now I need it to debug something in kotlinx and so am blocked.
