The solution for "Eclipse is running in a JRE, but a JDK is required"

Open the eclipse folder and access the eclipse.ini file:

 

Before change it ,you will find it don’t have the -vm parameter,so add it.

 

vm

C:\Program Files\Java\jdk1.6.0_10\bin\javaw.exe( It can be changed as your jdk path )

 

Note: It should be add before the -vmargs parameter.

 

See my eclipse.ini, just like this:

 1 -startup
 2 plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
 3 –launcher.library
 4 plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813
 5 -product
 6 org.eclipse.epp.package.jee.product
 7 –launcher.defaultAction
 8 openFile
 9 –launcher.XXMaxPermSize
10 256M
11 -showsplash
12 org.eclipse.platform
13 –launcher.XXMaxPermSize

15 –launcher.defaultAction
