1. Eclipse installation. Different Eclipse builds for different needs can be found  "Eclipse Downloads". I preferred Eclipse IDE for Java Developers or Eclipse IDE for Java EE Developers. More about difference you can found.  

2. Unpack you archive

   tar -zxvf eclipse-jee-galileo-linux-gtk.tar.gz

3. Installation of subversion client for eclipse.  Start Eclipse. Go to the menu Help ->Install new software -> Add ..  Add update site http://download.eclipse.org/technology/subversive/0.7/update-site/. Install Subversive SVN Team Provider.

4.  After Eclipse restart go the menu Window -> Preferences -> Team -> SVN When you first use the menu, you will be prompted to install connectors. Check SVN Kit 1.2.3.

5. Now you are ready to use Subversive plugin. Checkout some versioned project. For example http://anonsvn.jboss.org/repos/exo-jcr/
6. With help maven-eclipse-plugin create eclipse project.
7. Import new project to eclipse workspace. File->Import->Existing Projects into Workspace.
8. Set class path variables. Go to the Window -> Preferences -> Java -> Build Path ->  Class path variables. Add new variable M2_REPO  with the value of the path to your maven repository
