Hi! We've added arrow-optics to our project and as...

Hi! We've added arrow-optics to our project and as we used more and more, we often started getting build failures when files with @optics are moved: it seems there are some issues with gradle build cache (either local or remote) — old entries in build/generated are not being deleted an conflict with newer generated declarations.

Did you have some reports like this, perhaps there's a bug I could track?

[simon.vergauwen]

Do you have any other KSP things on the classpath? This sounds like a KSP related issue, not @optics. I've never heard of it before but I don't use remote Gradle cache.

[Alejandro Serrano Mena]

from my experience, KSP is quite brittle to removing things, in many cases old files are not removed

[dimsuz]

currently arrow-optics is the only thing using ksp.

[dimsuz]

thanks, I will look into ksp bugtracker then.

Another issue we've noticed is that for some users, files which use Arrow-Optics cause IDE (Android Studio) to report some error a-la: "IDE internal error: syntax highlighting is disabled".

But I failed to reproduce this one, will report if I'll have more details, for now it's unclear if arrow-optics is a true cause, but it's usage seems to correlate with this error.

"IDE internal error: syntax highlighting is disabled"

There is a couple of issues related to this opened on the YouTrack for the Kotlin plugin as well. I'm encountering this in code not using KSP or arrow-optics as well 😕

[dimsuz]

I see! I came to ask because our devs experience this friction after adding arrow-optics, and on the one hand we love this library and on the other they tell me: let's limit it's usage until these issues are resolved. A bit sad that it's not arrow-optics' fault and can't be quickly addressed because of this.

Is everyone experiencing these issues? Are you working in AS, or IDEA? I know they've been making a lot of changes recently, and IIRC Kotlin plugin is now baked into IDEA.

Miss-match between IDEA plugin, and Kotlin version can create some issues. At least that's what I've experienced in some cases. Not sure if miss-match with KSP version can also be related to this issue.

[simon.vergauwen]

Looking at my IDEA, I am on 1.8.20-dev Kotlin version, so it's not a stable release Kotlin version even 😕

[dimsuz]

We are using Android Studio (Electric Eel → stable),

Our project is using 1.7.21 and ksp 1.7.21-1.0.8 .
Kotlin plugin version is 221-1.8.0-release-for-android-studio-AS5591.52
So a newer one, yep.

Is everyone experiencing these issues?

Several people (including myself) definetly experienced issues with broken compilation due to issues with build/generated dir, but only one developer so far reported issues with syntax highlighting errors.

We are using both gradle local + remote build cache.

I will keep an eye on this and will collect errors and stacktraces to investigate a bit deeper in ksp + youtrack as you've suggested.

You mean these windows, right?

[dimsuz]

yep, exactly!

[dimsuz]

We tried to find them in idea.log, but so far failed to pinpoint it: too much logs 🙂

[simon.vergauwen]

Normally I get an "report issue" window, but with this issue I haven't seen that window anymore.

my team is seeing many android studio errors like those mentioned here
however we are on the bleeding edge using ...
