maven插件问题 ----- Eclipse is running in a JRE, but a JDK is required错误的解决

Eclipse安装了Maven插件后，可能会报这种错误：

控制台出现：

   1. Eclipse is running in a JRE, but a JDK is required 
   2.   Some Maven plugins may not work when importing projects or updating source folders. 

Eclipse is running in a JRE, but a JDK is required
  Some Maven plugins may not work when importing projects or updating source folders.

这是因为在Eclipse.ini配置中没有指定-vm参数，修改如下重启Eclipse问题就解决了：


1. 检查Eclipse正在使用的JRE

‘Window’ -> ‘Preferences’ -> ‘Java’ -> ‘Installed JREs’ 确定正在使用JDK而非JRE.

2. 配置Eclipse.ini
