Build fails for Android on M1 Macs

[euriasb]

Build fails for Android on M1 Macs with the following error:

Execution failed for task ':flutter_locker:generateDebugProto'.
> Could not resolve all files for configuration ':flutter_locker:protobufToolsLocator_protoc'.
   > Could not find protoc-3.9.1-osx-aarch_64.exe (com.google.protobuf:protoc:3.9.1).
     Searched in the following locations:
         [https://jcenter.bintray.com/com/google/protobuf/protoc/3.9.1/protoc-3.9.1-osx-aarch_64.exe]()

After some googling, the issue is that there are no binaries for M1 Macs, there are however x86 compatible binaries, this github issue explains how to make protobuf select the appropriate binary, I did it locally and it worked successfully.

I'm having the same problem but the workarounds did not work for me, I'm stuck

I'm having the same problem but the workarounds did not work for me, I'm stuck

The exact thing I do when I test on Android is I just hard code this on the gradle file:

protobuf {
    // Configure the protoc executable
    protoc {
        // Download from repositories
        artifact = 'com.google.protobuf:protoc:3.9.1:osx-x86_64'
    }
    plugins {
        javalite {
            // The codegen for lite comes as a separate artifact
            artifact = 'com.google.protobuf:protoc-gen-javalite:3.0.0:osx-x86_64'
        }
    }
    generateProtoTasks {
        all().each { task ->
            task.plugins {
                javalite { }
            }
        }
    }
}

So, just hardcode :osx-x86_64 after the protoc and javalite artifacts.

Hope this helps you @tudor07

@euriasb unfortuntaly that does not work for me

• What went wrong:
  A problem occurred evaluating project ':app'.

Could not find method protobuf() for arguments [build_a3bkpzk12frubfik9jilgxszt$_run_closure6@3d992407] on project ':app' of type org.gradle.api.Project.

@zenled @itsJoKr any chance you can look into this issue?

We are looking into this.

As @euriasb mentioned, the current workaround is to find the .../.pub-cache/hosted/pub.dartlang.org/flutter_locker-2.0.3/android/build.gradle file and chenge the protobuf {... section to:

protobuf {
    // Configure the protoc executable
    protoc {
        // Download from repositories
        artifact = 'com.google.protobuf:protoc:3.9.1:osx-x86_64'
    }
    plugins {
        javalite {
            // The codegen for lite comes as a separate artifact
            artifact = 'com.google.protobuf:protoc-gen-javalite:3.0.0:osx-x86_64'
        }
    }
    generateProtoTasks {
        all().each { task ->
            task.plugins {
                javalite { }
            }
        }
    }
}

Any updates? I dread testing on Android because of this issue. Everytime I need to test Android I have to disable flutter_locker everywhere in the app. @zenled

Any luck on this, above mentioned workaround is not working for me.

[itsJoKr]

Can you try this until we get out the new version:

  flutter_locker:
      git:
        url: https://github.com/infinum/flutter-plugins-locker
        ref: 781f02ffa14bef819a9ee5d4c9ac98a42cfc9e57

You can also try 2.0.4 and reopen if it's still issue.

flutter_locker: ^2.0.4
