Is there any option to generate FIR code to get IntelliJ code completion based on (changes of) resource/ordinary files? Use-case: I have a code generator producing kotlin source code based on a (openapi) file and I want to provide code completion when I change the openapi file. As a workaround, I could create an IntelliJ plugin that runs the code generator (via Gradle) every time on a change.

While your request is valid.
Id like to suggest a tooling based solution.
I.e. write Gradle task that generates from openApi spec kotlin code. Then use Intellij FileWatcher https://www.jetbrains.com/help/idea/using-file-watchers.html to trigger this Gradle task every time openapi spec is modified. If Gradle task is written properly it would run as fast as code generation takes.

Yeah, that’s my current solution too but the speed really depends on the Gradle setup of the users. While my Gradle task is fast and supports caching, not every user has a Gradle build that is fast to execute (by using build and configuration cache).

Same.
Calling Gradle from IJ feels OK-ish for small projects but any large project will just take too much configuration time

[mbonnin]

@hfhbd what about a compiler plugin that takes your OpenAPI file as a String input?

[mbonnin]

mmmm never mind that will probably not detect changes to the input unless there is a Gradle sync or so...

[Anton Lakotka [JB]]

Yeah, I understand that Gradle can be a problem here. As alternative I might suggest gradle continuous run. But since you want to share it with other users. Then it is awful UX.

I've tried continuous run. This is even worse for large projects because now they end up with 2 daemons using 24GB (or more) heap each 😬
