Unless I specified my maven local repository in my project.properties file under my project root as such:

maven.repo.local = ..\\..\\tools\\my_repository\\.maven\\repository

My meven IDE synchronizer would not rely on the maven local repository I specified in the eclipse maven preferences Location form.

So I upgraded my eclipse through eclipse update site to version 3.0.2. Just hoping it will fix the stuff by itself

yet another bug or configuration issue while lauching maven on my projects, I systematically got:

!MESSAGE An internal error occurred during: "Launching".
!STACK 0
java.lang.NoSuchMethodError: org.eclipse.debug.internal.ui.DebugUIPlugin.getProcessConsoleManager()
Lorg/eclipse/debug/internal/ui/views/console/ProcessConsoleManager;
 at org.mevenide.ui.eclipse.launch.configuration.MavenLaunchDelegate.launch(MavenLaunchDelegate.java:143)

But No, as said I have installed the right plugin : using the site descriptor located at : http://mevenide.codehaus.org/release/eclipse/update/3.0/site.xml

So i uninstalled it, using eclipse > Help > Software updates > manage configuration
and reinstalled it using this specific update site: http://mevenide.codehaus.org/release/eclipse/update/3.0/site.xml no the one introduced on their web page: http://mevenide.codehaus.org/release/eclipse/update/site.xml It worked better !!! :-)
