下载java jdk，并安装java jdk。下载地址：http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
在eclipse的菜单中，进入 Window > Preferences > Java > Installed JREs > Execution Environments，选择JavaSE-1.6, 在右侧选择jdk.

然后在maven菜单中使用 “update project ...”.

但是试了时候不好用
但是重复尝试了很久都不行。
需要执行下以命令：Maven updateMaven cleanproject clean
build project然后多次执行Maven Install，直到打包成功为止。
