With Subversive being an official Eclipse project (2007) and the recent Eclipse 3.5 Galileo release (2009), you may be wondering why Eclipse still does not have SVN support built-in.
But don’t fuss, because it’s not that hard to configure SVN support (using Subversive) with a few simple steps. This document aims to guide you with the install process.
The first time you try to run Eclipse Galileo and click any of the update sites, you’ll probably receive the “Unable to read repository at …” error like what is shown below:

To fix this problem, simply select “Galileo” (or any other update site you wish to use) from the “Available Software Sites” link (Help>Install New Software) and click the “Test Connection” option on the right.

Click “OK” when done and select “Galileo” from the “Available Software” dropdown.

From the Galileo Update site, choose “Collaboration > Subversive SVN Team Provider”.

Click Finish/OK when done. Due to licensing restrictions, the connectors need to be installed using another update site.
To do this, simply “Add” the “Subversive SVN Connectors” Update Site: http://community.polarion.com/projects/subversive/download/eclipse/2.0/galileo-site/

Select the Subversion Connectors you need (select all if you’re not sure which ones) and Install.

After the installation process, you will be asked for restart of a Eclipse for the changes to take effect.
To see the available options for SVN, open the “SVN Repository Exploring” perspective.

Hope this helps. Comments and feedback are much appreciated.
Thanks.

Thank you, very useful information =)
