Hi Arrow team I m having trouble to setup KSP for Optics on

Question

Hi Arrow team I m having trouble to setup KSP for Optics on a Kotlin Compose Multiplatform project Android + Desktop I m 100 doing something wrong but wanted to save some time and ask for advice or a sample project setup link Here s my code <https github com Ivy Apps ivy wallet tree multiplatform> What I want to achieve Have a ` common` module containing all the data classes for the app and have Lens generated for them via ` optics` it worked perfectly and the setup was quite easy when it was Android only app but now I got stuck Preferably optics to work on all modules but it ll be sufficient just for the ` common` one To see the generated code in my IDEs not red in other modules too I use both Android Studio + Idea P S I tried a lot of things but eventually removed the KSP stuff because I couldn t get the project to compile

If this isn t easy my best workaround is to use ChatGTP + Copilot to generate the Lens for me smile But hopefully I won t resort to that
