Configuring Eclipse for Maven plugins

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 using JDK installs.



11/05/11 18:18:39 BST: Eclipse is running in a JRE, but a JDK is required
Some Maven plugins may not work when importing projects or updating source folders.
11/05/11 18:18:45 BST: Updating index central|http://repo1.maven.org/maven2
11/05/11 18:18:48 BST: Updated index for central|http://repo1.maven.org/maven2

Change eclipse.ini from

-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
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m


To


-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
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Java\jdk1.6.0_23_64\bin\javaw.exe
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m


Notice the new line, it is important

Also:

We need to change the installed JRE's in Eclipse preferences



Click Add to create a new JRE








Locate the root folder of you downloaded JDK: Note in this case I am using a 64bit JDK as I have a 64bit Eclipse



Remember to set the new installed JRE
