Kapt does not allow protobuff-generated classes

Question

I get this error during build:

e: /Users/some/path/SomeClass.java:86: error: cannot find symbol 
e:       
e:     static ConnectionType getConnectionType(Context context) { 
e:            ^ 
e:   symbol:   class ConnectionType 
e:   location: class SomeClass

Where ConnectionTypeis the class generated by protobuf. This way, it seems that kapt is not allowing the generated classes.

What have i tried?

First I added a plugin kotlin-apt:

apply plugin: 'kotlin-kapt'

Then I added the classes created with brotobuf to the source set:

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
    main.java.srcDirs += 'build/generated/source/proto/main/java'
}

And also I want to create classes before kapt starts working. Therefore, I order gradle tasks this way:

afterEvaluate {
    def protoTasks = []
    tasks.each { task ->
        if (task.name.contains('proto') || task.name.contains('Proto')) {
            protoTasks.push(task)
        }
    }

    tasks.each { task ->
        if (task.name.startsWith('kapt')) {
            task.dependsOn protoTasks
        }
    }
}

But all this does not help, I still have the same error. How to solve it?

Answer 1

- protobuf. , :

sourceSets {
    // ...
    main.java.srcDirs += 'build/generated/source/proto/flavor/java'
}

sourceSets {
    // ...
    main.java.srcDirs += 'build/generated/source/proto/main/java'
}
