POM依赖不起作用（Eclipse，Maven，POM）

我在Eclipse（Helios）中有一个使用Maven pom.xml的项目。我的项目是一个将使用Hibernate，MySQL的Web应用程序。POM依赖不起作用（Eclipse，Maven，POM）

但是，我无法得到pom.xml的权利。我对maven很陌生，不能相信建立依赖关系是如此艰难（其他人有类似的expierience /或者我是愚蠢的）。

我的pom.xml的是在这里：

所有上述错误消失，如果我从pom.xml文件删除mysql的依赖。我完全困惑为什么mysql应该依赖于这些。

是不是Maven应该自动解决这些依赖关系？毕竟这不是使用Maven的全部想法。

请专家指导我正确的方向。
