M1版本Mac针对性配置

M1版本Mac针对性配置

项目编译报错信息解决方案：

Could not find artifact com.google.protobuf:protoc:exe:osx-aarch_64:3.6.1 in public (http://nexus.xxx.com/repository/maven-public/)

公司项目中使用的是google的protobuf这种协议数据交换格式

在所有项目中配置有以下代码的地方都会报错

<configuration>
    <protocArtifact>com.google.protobuf:protoc:3.6.1:exe:${os.detected.classifier}</protocArtifact>
    <pluginId>grpc-java</pluginId>
    <pluginArtifact>io.grpc:protoc-gen-grpc-java:1.19.0:exe:${os.detected.classifier}</pluginArtifact>
</configuration>

原因：

M1芯片使用的是最新的 osx-aarch_64 架构，${os.detected.classifier}获取当前系统架构会获取到osx-aarch_64的exe文件。而nexus私有仓库中没有此版本。从而导致错误！！

如下图所示：私有仓库中版本只有osx-x86_64

处理方案一（不推荐）

把${os.detected.classifier}更改为osx-x86_64.

<configuration>
    <protocArtifact>com.google.protobuf:protoc:3.6.1:exe:osx-x86_64</protocArtifact>
    <pluginId>grpc-java</pluginId>
    <pluginArtifact>io.grpc:protoc-gen-grpc-java:1.19.0:exe:osx-x86_64</pluginArtifact>
</configuration>

处理方案二（推荐）

把${os.detected.classifier}获取的架构强制更改为osx-x86_64，代码不需要更改，在/Users/jarvan/.m2/settings.xml中增加一个profile标签和一个activeProfile标签

<profile>
  <id>apple-silicon</id>
  <properties>
    <os.detected.classifier>osx-x86_64</os.detected.classifier>
  </properties>
</profile>

<activeProfiles>
  <activeProfile>apple-silicon</activeProfile>
</activeProfiles>

完整配置如下：
