Eclipse4.7创建Maven项目报错解决方法

最近换了最新版的Eclipse，发现创建Maven项目时，pom文件报错，而且不能自动下载jar包。经过查找资料，终于找到了解决方法。
报错如下：

 maven2 was cached in the local repository, resolution will not be reattempted until the update interval 
 of central has elapsed or updates are forced. Original error: Could not transfer artifact

为了解决这些报错，只需要找到本地仓库 m2\repository下找到这些文件夹，然后将其全部删除。
然后在Eclipse中的项目中右键Maven-update project,勾选Force Update更新后，则可以自动下载Jar包。
