Important

Adaptive uses the K2 compiler heavily. Starting from IntelliJ IDEA 2024.2 K2 support is available for multiplatform projects. To have it, you have to enable K2 and the non-bundled plugins.

Enable K2

1. Settings
2. Languages & Frameworks
3. Kotlin
4. Enable K2 mode

Enable 3rd party compiler plugins in the IntelliJ registry

See KTIJ-29248 for details.

1. Shift-Shift
2. select Actions on top
3. type in Registry
4. find kotlin.k2.only.bundled.compiler.plugins.enabled and set it OFF

Technically you could avoid the registry setting by adding some boilerplate manually, but I think it's just easier to have it. Also, the issue above is scheduled for 2024.3, so hopefully this setting won't be needed anymore.

Android issues

As of now, the Android plugin in IntelliJ does not support K2, so syntax highlighting does not work. Switching back to K1 mode works, but then Adat classes do not work. Luckily we don't need to edit Android specific code too much.

Import issues

There are a few import related issues when in K2 mode, see KTIJ-31100 for details. Hopefully as K2 matures these will go away.
