集成Google Play Services插件构建失败：找不到gpgs-plugin-support:0.11.01

我正在构建Android应用，已安装Google AdMob包与Google Play Services插件，但后者导致构建失败，提示无法找到com.google.games:gpgs-plugin-support:0.11.01。已正确配置依赖文件路径，多次执行强制解析操作，修改过JAVA_HOME环境变量，但问题仍未解决，怀疑AdMob与Google Play Services存在冲突。

解决方法 #

• 检查本地依赖文件完整性：确认Assets/GooglePlayGames/com.google.play.games/Editor/m2repository/com/google/games/gpgs-plugin-support/0.11.01目录下存在.pom和.jar文件，若缺失则重新下载完整的Google Play Services插件，或手动补充该依赖包。

• 修复Gradle本地仓库路径：将mainTemplate.gradle中本地maven仓库的URL改为绝对路径格式，避免路径拼接错误：

  maven {
      url uri("${project.rootDir}/Assets/GooglePlayGames/com.google.play.games/Editor/m2repository")
  }
  

• 统一Google服务版本：AdMob的play-services-ads:22.5.0与GPGS依赖可能存在版本不兼容，尝试升级Google Play Services插件到最新稳定版，或调整AdMob版本与GPGS依赖的Google服务版本对齐。

• 清理缓存并重新解析：删除Unity的Library/Bee和Library/Android目录，执行Assets > External Dependency Manager > Android Resolver > Force Resolve，重启Unity后重新构建。

• 移除重复仓库配置：删除mainTemplate.gradle中重复的https://maven.google.com仓库配置，保留一个即可避免仓库优先级冲突。
