The Maven Integration requires that Eclipse be running in a JDK, because a number of Maven core plugins are using jars from the JDK.
Please make sure the -vm option in eclipse.ini is pointing to a JDK and verify that Installed JRE’s are also using JDK installs.
（1）set your JDK as a default Java environment in eclipse (default installed JRE)
Open 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）add path to your SDK in eclipse.ini
open ‘eclipse.ini’ and add there: -vm path_to_javaw_on_your_machine，so in my example it will be (jdk1.6.0_17 on Windows):
Notice 1: Do not use paths with spaces! Replace all dir names with spaces to their shortcuts. For example: ‘Program Files’ is ‘Progra~1′.
Notice 2: ‘-vm’ is in the first line, path is in the second line
your ‘eclipse.ini’ looks like this:
Notice : ‘-vm’ must be “-vmargs” above
Restart eclipse and everything should be fine.
