Proto datastore jetpack compose - gradle dependencies exception

Question

I followed this codelab from the android developer platform: https://developer.android.com/codelabs/android-proto-datastore#4

Added the same exact dependencies as shown in the codelab and I get the following gradle exception when trying to sync

A problem occurred configuring project ':app'.

Could not get unknown property 'source' for generate-proto-generateDebugProto of type org.gradle.api.internal.file.DefaultSourceDirectorySet.

I have no idea what the issue could be, tried to upgrade the versions shown in the codelab, looked up the issue everywhere, but can't seem to find anyone that experienced the same thing. Any idea?

Answer 1

I had to use the 0.9.1 version of protobuf

plugins {
    id "com.google.protobuf" version "0.9.1"
}

Answer 2

The configuration below worked for me.

At module's build.gradle file:

plugins {
    ...
    id "com.google.protobuf" version "0.9.1" 
}
dependencies {
    implementation  "androidx.datastore:datastore:1.0.0"
    implementation  "com.google.protobuf:protobuf-javalite:3.18.0"
    ...
}
protobuf {
protoc {
    artifact = "com.google.protobuf:protoc:3.21.7"
}

generateProtoTasks {
    all().each { task ->
        task.builtins {
            java {
                option 'lite'
            }
        }
    }
}
}
