使用方案

虽然上述错误信息中，提示了可以使用 Maven 命令可以将依赖安装到本地，但是推荐大家使用 Maven 私有仓库

上传 Maven 私有仓库：

 xuxiaowei@172  ~/Downloads  cat settings.xml
<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

# deploy:deploy-file：发布
# -s settings.xml：指定 Maven settings.xml 文件位置，用于配置 Maven 发布时使用的用户名、密码
# -DrepositoryId=maven-loong64-hosted：Maven settings.xml 中 Maven 仓库的 ID
# -Durl=http://172.25.25.62:48081/repository/maven-loong64-hosted/：Maven 仓库地址

mvn deploy:deploy-file \
  -DgroupId=io.grpc \
  -DartifactId=protoc-gen-grpc-java \
  -Dversion=1.78.0 \
  -Dclassifier=linux-loongarch_64 \

使用效果

maven-loong64-hosted 仓库：

  1. Type（仓库类型）：hosted 宿主仓库
  2. Version policy（版本策略）：Mixed 包含 Release 正式版、Snapshot 快照版

maven-public 仓库：

  1. Type（仓库类型）：group 分组仓库，包含了 maven-loong64-hosted 仓库

强烈建议 使用 -U 强制下载，否则由于 Maven 仓库机制的问题，存在近期产生的 _remote.repositories、protoc-gen-grpc-java-1.78.0-linux-loongarch_64.exe.lastUpdated 文件，不会下载远端仓库中新增的依赖，当然不使用 -U 参数，手动删除 _remote.repositories、protoc-gen-grpc-java-1.78.0-linux-loongarch_64.exe.lastUpdated 文件 等文件，也可以达到 -U 效果，不过太麻烦了

-U 命令并非 Snapshot 快照版专属参数
