hi guys 🙂 I am developing a simple KSP annotation processor and applying it on a sample android library project, which has

debug

and

release

build types. Different source folders are created for each build type, i.e.

build/generated/ksp/debug/kotlin

and

build/generated/ksp/release/kotlin

respectively. In order to be able to consume the generated code I have added the following code in my

build.gradle.kts

buildTypes {
        getByName("debug") {
            sourceSets {
                getByName("main") {
                    kotlin.srcDir(file("build/generated/ksp/debug/kotlin"))
                }
            }
        }
        getByName("release") {
            sourceSets {
                getByName("main") {
                    kotlin.srcDir(file("build/generated/ksp/release/kotlin"))
                }
            }
        }
    }

Unfortunately, if I run

kspDebugKotlin

and

kspReleaseKotlin

w.o. cleaning the

build

folder my generated classes are marked with errors in Android Studio. The error reads

Redeclaration

as if both folders were added to the same source set. Do you know how to get rid of this error? Using: • ksp

1.5.31-1.0.0

• Kotlin

1.5.31

• Android Studio Bumblebee • AGP

7.1.0

You are indeed adding both debug & release generated folders to the main source set 🙂

Right, you need to use android gradle plugin to add the generated source from corresponding building variant. On a side note, the generated files should be added to compile path by KSP, are you adding to source set in gradle configure file for IDE indexing?

@efemoney thank you so much! I think I was deceived by the comments in https://github.com/google/ksp/issues/37 😅
