Eclipse is running in a JRE, but a JDK is required错误

详细错误：

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

解决方法 在eclipse目录下eclipse.ini,添加如下两行，注意这行要加在-vmargs之前，
-vm
C:\Program Files\Java\jdk1.6.0_14\bin\javaw.exe

-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
