在 Flutter/Android 构建中找不到 protoc-3.9.2-osx

Question

我正在开发一个 Flutter 应用程序，该应用程序集成了一个使用 Protobuff 的本机包。我在 Android Studio 和 Mac（Apple 发布）上工作。

在 Windows 上，应用程序会构建，但由于我在 MacO 上工作，因此无法再构建应用程序。我收到以下错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ‘:mypackage:generateDebugProto’.
> Could not resolve all files for configuration ‘:mypackage:protobufToolsLocator_protoc’.
   > Could not find protoc-3.9.2-osx-aarch_64.exe (com.google.protobuf:protoc:3.9.2).
     Searched in the following locations:
         https://jcenter.bintray.com/com/google/protobuf/protoc/3.9.2/protoc-3.9.2-osx-aarch_64.exe

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 888ms
Exception: Gradle task assembleDebug failed with exit code 1

iOS 上的构建也不起作用。

如何解决此错误？您对问题出在哪里有任何想法吗？

我找到了一个基于https://github.com/grpc/grpc-java/issues/7690的解决方案

我已创建文件：$HOME/.gradle/gradle.properties 与：

protoc_platform=osx-x86_64

我的 build.gradle ：

protobuf {
// Configure the protoc executable
protoc {
    // for apple m1, add protoc_platform=osx-x86_64 in $HOME/.gradle/gradle.properties
    if (project.hasProperty('protoc_platform')) {
        artifact = "com.google.protobuf:protoc:3.9.2:${protoc_platform}"
    } else {
        artifact = "com.google.protobuf:protoc:3.9.2"
    }
}
plugins {
    javalite {
        // The codegen for lite comes as a separate artifact
        if (project.hasProperty('protoc_platform')) {
            artifact = "com.google.protobuf:protoc-gen-javalite:3.0.0:${protoc_platform}"
        } else {
            artifact = "com.google.protobuf:protoc-gen-javalite:3.0.0"
        }
    }
}
