element 'dependency' cannot have character [children], because the type's content type is element-only.

在pom.xml中添加相关的maven依赖时，因此一时间maven官网打不开，就在一篇博客上复制了过来，一直报element 'dependency' cannot have character [children], because the type's content type is element-only.的错误，应该是复制过来的东西在某些地方多了写奇奇怪怪的东西，还是乖乖地到官网复制过来吧。。。
