Wolfram Workbench Installation Issue

In attempting to reinstall Wolfram Workbench 2.0 after a unused hiatus and system reconfiguration, I downloaded both Eclipse and Workbench. Both seem to run. However, in following the Wolfram video on installing WWB Adam Berry suggests that before getting started one should Select the Help Menu and the Install Workbench Extras. Following the video I check the box for the single available feature Subclipse to add client support for SVN source control to the WWB. In pressing Finish I get the error:

“Could not connect to update site: http://subclipse.tigris.org/update_1.6.x”

Consequently, I can not perform subsequent steps as given in the Workbench Installation Video. It seems that the subclipse.tigris.org pages references are now missing and the site is decommissioning. Checking this subclipse.tigris.org website indicates it will be gone by July 2020,but you had to ask before 1 June 2020. The files referred to no longer seem to exist. For example, there is no “Team” support as suggested in the video.

How can one resolve this issue? Is it even necessary any longer to do this? If so, how can one now setup WWB to establish the setup features referred to in the video? If not necessary, perhaps the Installation Video needs to updated.
