Eclipse and Maven: JDK error - eclipse

Question

what do I need to write in my eclipse.ini to get rid of this warning:
The Maven Integration requires that Eclipse be running in a JDK,
beacuase a number of Maven core plugins are using jars from the JDK.
Please make sure the -vm options in eclipse.ini is pointing to a JDK
and verify that Installed JREs are also using JDK installs.
My ini says this and the problem is not solved:
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.2.R36x_v20101222
-showsplash org.eclipse.platform
--launcher.XXMaxPermSize 256m
--launcher.defaultAction openFile
-product org.eclipse.epp.package.java.product
--launcher.defaultAction openFile
--launcher.XXMaxPermSize 256M
-vm C:\Program Files\Java\jdk1.6.0_25\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx384m
Update: The above definitely doesn't change my vm I checked it according to this answer and it says I'm still running eclipse.vm=C:\Windows\System32\javaw.exe
Update2: A suggested on several websites I tried to run eclipse from the commandline as .\eclipse -vm "..\Java\jdk1.6.0_25\bin\javaw.exe" and it worked!!! In "Eclipse Installation Details"->"Configuration" it now says eclipse.vm=C:\Program Files\eclipse\\..\Java\jdk1.6.0_25\bin\javaw.exe

Answer 1

Did you try using slashes instead of backslashes for the folder of your jdk?

Answer 2

As has been suggested in other answers you should both change backslashes to forward slashes in your JDK path and put -vm and the JDK path on different lines. This is what works for me:
-vm
C:/Program Files (x86)/Java/jdk1.6.0_26/bin/javaw.exe
I have these two lines as the first ones in my eclipse.ini file, but that should not be required.

Answer 3

Here is my eclipse.ini (eclipse 3.6) and maven works fine
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.2.R36x_v20101222
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx384m
I just downloaded eclipse from official site, download maven 2.2.1 from apache site, installed
m2eclipse - http://m2eclipse.sonatype.org/sites/m2e
m2eclipse Extras http://m2eclipse.sonatype.org/sites/m2e-extras
(Install new software)
Set up my maven installation in Window->Preferences->Maven->Installations
and that's all for me to work with maven.

Answer 4

Have you tried an enter between -vm and the java path? I think it needs a new line. You can also try pointing to the jvm.dll instead of the .exe
