控制台输出的错误信息如下：

网上找到的解决方案如下：

1. 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

2. 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.

3. 然后在maven菜单中使用 “update project ...”.

但是重复尝试了很久都不行。

后来通过同事指点，需要执行下以步骤：

Maven update

Maven clean

project clean
build project

然后再重复的执行Maven Install，直到打包成功为止。
