The Maven Integration requires that Eclipse be running in a JDK

若在Eclipse启动时，出现上图中的情况解决方法：

1：打开eclipse Click on ‘Window’ -> ‘Preferences’ -> ‘Java’ -> ‘Installed JREs’.

If you can’t find any JDK on the list -> click ‘Add’ -> ‘Standard VM’ -> set all paths and click ‘Finish’.

After that – check this JDK on the list of installed JREs and click ‘OK’.

2:在eclipse的安装目录中找到eclipse.ini文件编辑这个文件

-startup

plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519

-product

org.eclipse.epp.package.jee.product

--launcher.XXMaxPermSize

256M

-showsplash

org.eclipse.platform

--launcher.XXMaxPermSize

256m

-vm

D:\Java\jdk1.5.0_08\bin

-vmargs

-Dosgi.requiredJavaVersion=1.5

-Xms40m

-Xmx512m

黑色粗体部分就是需要添加的内容

注意：添加-vm后就需要另起一行，并且-vm一定要在-vmargs这个参数的上面。
