您的 Maven 安装无法联系中央存储库来解决列出的依赖项，这通常是连接问题。

你有代理吗？如果是这样，你可以在maven的settings.xml上配置maven来访问它。 (在 Windows 上，它位于您的用户配置文件文件夹中)

如果您仍然无法自动下载依赖项，您可以随时手动下载它们并将它们安装到本地存储库，并发出:

mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>

对于您的第一个依赖项应该类似于:

mvn install:install-file -Dfile=google-collections.jar -DgroupId=com.google.collections -DartifactId=google-collections -Dversion=1.0 -Dpackaging=jar
