我想创建一个PlayN游戏，但在Eclipse中我得到了这个错误：

我该怎么办？请帮忙！

您的maven安装无法联系中央存储库以解决列出的依赖项，这通常是一个连接问题。
你是代理人吗？如果是这样，您可以配置maven以在maven的settings.xml上访问它。 （在Windows上，它位于您的用户个人资料文件夹中）
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，发出：
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
对于你的第一个依赖应该是这样的：
mvn install:install-file -Dfile=google-collections.jar -DgroupId=com.google.collections -DartifactId=google-collections -Dversion=1.0 -Dpackaging=jar
