I’m playing with my first kapt processor to generate interfaces, and it works when compiled with gradle, but IDEA seems unaware of the processor. I wrote a post over on kotlinlang: https://discuss.kotlinlang.org/t/kapt-idea-doesnt-know-about-generated-classes/6894 if anyone has a moment to take a look at my code.

What is your target directory for generated code?
Did you try some existing AP (like Dagger or AutoValue), does it work for you?

[gildor]

Just tried your demo and it’s works for me.

[christopher]

I’ll try a different AP and see if that works then.

[christopher]

Thanks for giving it a try.

[gildor]

Yeah, it’s just work for me
On Idea Ultimate 2018.1

[christopher]

Ah, I’m on 2017.3. Also ultimate

[gildor]

Idea and Kotlin plugin actually had some changes recently about detection of generated sources from Gradle. But I pretty sure those changes been released on some 2017.x version

Also way as you import project can be different.
I use option “Create separate module per source set”, “explicit module groups” and use default gradle wrapper, so actually default settings.
I remember that some option can change different source roots behaviour of IDE, but not sure now

[christopher]

I’m going to ask a dumb question: Did you compile (assemble at least) before the interface became available? and if you clean does it become unresolved again?

[christopher]

Maybe I just have unreasonable expectations…

[gildor]

Yes, you should assemble first (build does assemble too + tests)

[gildor]

yes, correct, after clean Foo is not available anymore

[gildor]

This is default behaviour for Java projects with AP

[gildor]

But for example Android projects generate sources during synchronisation, but it’s completely Android Plugin feature

[christopher]

ah… so I’ve simply been fooled by things like Spring and Lombok, which have IDE plugins, to think that it’s normal for annotations to instantly take effect.

[gildor]

Yes, not sure about Spring code generation, but Lombok should have IDE support, otherwise just nothing will work
