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?

I also get the same error – Vern

Answer 1

I had to use the 0.9.1 version of protobuf

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

That didn't help at all for me. – Sutler

plugins{ id("com.google.protobuf") version "0.9.1"} protobuf { protoc { artifact = "com.google.protobuf:protoc:3.21.7" } generateProtoTasks { all().forEach { task -> task.builtins { java { "lite" } } } } } --working for me, built successfully – Sullivan

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'
            }
        }
    }
}
}

This was the solution for me as well. Thank you very much! – Markmarkdown

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

....

protobuf {
        protoc {
            artifact = "com.google.protobuf:protoc:3.21.7"
        }
    
        generateProtoTasks {
            all().forEach { task ->
                task.builtins {
                    java {
                        "lite"
                    }
                }
            }
        }
    }

Try to build. Newer version of ProtoBuf
