现象
执行 mvn clean package -DskipTests 对 ORC 打包失败，报错如下：

分析
从报错即可看出，打包时由于系统为 osx-aarch_64 架构，所以会去找 protoc-2.5.0-osx-aarch_64 名字样式的包，查看 nexus 仓库，没有这种名字的包:
修改思路当然是将 protoc-2.5.0-osx-aarch_64.exe 替换为 protoc-2.5.0-osx-x86_64.exe。查看文档知系统架构通过 os.arch 指定即可，于是执行 mvn clean package -DskipTests -Dos.arch=x86_64，打包成功。
查了下github上的解决方案，若 pom.xml 文件中使用的插件能设置 protoc 的 os arch 类型
<protocArtifact>com.google.protobuf:protoc:3.14.0:exe:${os.detected.classifier}</protocArtifact>
也可以直接修改该 os arch
<protocArtifact>com.google.protobuf:protoc:3.14.0:exe:osx-x86_64</protocArtifact>
或修改 ./m2/settings.xml 文件：
<settings>
...
<activeProfiles>
<activeProfile>
apple-silicon
</activeProfile>
...
</activeProfiles>
<profiles>
<profile>
<id>apple-silicon</id>
<properties>
<os.detected.classifier>osx-x86_64</os.detected.classifier>
</properties>
</profile>
...
</profiles>
...
</settings>
如果没有本地安装maven，也可以直接在IDEA中直接配置maven执行参数，
Preferences -> Build,Execution,Deployment -> Build Tools -> maven -> Runner -> VM Options
中填入 -Dos.arch=x86_64 指定maven运行时获取到的芯片名。
