I’m trying to install Subclipse in SpringSource Tool Suite (version 2.8.1.RELEASE). Following the instructions at http://www.dariopardo.com/dev-env/how-to-integrate-sts-or-eclipse-with-subversion-svn/, I go to Help->Install New Software. I enter the site http://subclipse.tigris.org/update_1.6.x in the Work with text field. Then I get to choose from “Core SVNKit Library”, “Optional JNA Library”, and “Subclipse”.
No matter what components I select, I get the error message “Cannot complete the install because one or more required items could not be found.” after clicking Next. I have no problem with my internet connection.
I got the same error message when trying to install Subclipse from a locally stored site-1.0.6.zip file (downloaded from http://subclipse.tigris.org/servlets/ProjectDocumentList?folderID=2240) instead of the above URL.
There seems to be no STS documentation on this. Help, please!
Solved the problem by removing STS and reinstalling it. Apparently STS is not the world’s most stable software product.
