Protobuf processing broken

[kanetik]

I have set up Proto Datastore in my app, and it was all working perfectly until I upgraded the KSP plugin from version 1.9.10-1.0.13 to 1.9.20-1.0.14 tonight. After some experimenting, I can say that it does work up to 1.9.20-RC-1.0.13 and does not work from 1.9.20-RC2-1.0.13 through 1.9.20-1.0.14, so it appears that one of the changes introduced in the RC2 release broke something w/ that processing.

I have my proto file in the standard location (src\main\proto) and my configuration in build.gradle.kts (the module one) is

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.25.0"
    }
    generateProtoTasks {
        all().forEach { task ->
            task.builtins {
                id("java") { option("lite") }
                id("kotlin") { option("lite") }
            }
        }
    }
}

The error I get when the build fails is:

I am also experiencing the same issue where I am unable to update to 1.9.20

[erfansn]

I have the same issue I don't know what I can do.

Snippet from my build.gradle.kts that works for my project:

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.25.0"

        generateProtoTasks {
            all().forEach { task ->
                task.builtins {
                    create("java") {
                        option("lite")
                    }
                }
            }
        }
    }
}

androidComponents {
    onVariants(selector().all()) { variant ->
        afterEvaluate {
            val protoTask =
                project.tasks.getByName("generate" + variant.name.replaceFirstChar { it.uppercaseChar() } + "Proto") as GenerateProtoTask

            project.tasks.getByName("ksp" + variant.name.replaceFirstChar { it.uppercaseChar() } + "Kotlin") {
                dependsOn(protoTask)
                (this as org.jetbrains.kotlin.gradle.tasks.AbstractKotlinCompileTool<*>).setSource(
                    protoTask.outputBaseDir
                )
            }
        }
    }
}

Whose responsibility is it to resolve the issue?

Here is the snippet for my workaround, based on the above and the one for SQLDelight I found here.

androidComponents {
    onVariants(selector().all()) { variant ->
        afterEvaluate {

Just have this above workaround as legacy Groovy for someone might need it

androidComponents {
    onVariants(selector().all(), { variant ->
        afterEvaluate {
            def capName = variant.name.capitalize()
            tasks.getByName("ksp${capName}Kotlin") {
                setSource(tasks.getByName("generate${capName}Proto").outputs)
            }
        }
    })
}

I am experiencing this as well. The workaround that @felixzheng posted above fixes it.
