Maven错误 diamond operator is not supported in -source 1.5 (use -source 7 or higher to enable diamond operator)问题解决

如果在Maven构建时出现：

diamond operator is not supported in -source 1.5
(use -source 7 or higher to enable diamond operator)

的错误，是由于使用了complier的插件版本为1.5导致的，因为在默认不配置情况下，Maven3默认为1.5，此时如果项目上使用泛型，那么就会出现错误。

解决方法就是升级为1.8，具体参考：http://www.cnblogs.com/EasonJim/p/6810758.html
