Within eclipse, with Subclipse installed, if I right click a project and select \"team\" there are normally 2 options:
I had the exactly same situation with Yaniv above.
If you upgraded your Eclipse recently, make sure you're still using the same SVN plugins... :)
In my case, I upgraded my Eclipse and accidentally installed Subversive instead of Subclipse. The existing .svn directory of the project contained data in the format expected by Subclipse, and so Subversive got confused (e.g. but not showing the "Share Project" option).
My solution is like below:
Exported the current project in the new workspace into .war file.
Double-checked the current project is in the svn repository.
Removed the project in the new workspace completely once I was sure that I have the exported .war file and svn repository so that I will be able to import the project again.
Imported the project from svn, and checked out the project from the svn. (Or, you can import the project from the .war file and you will be able to Share Project)
-> It worked well with the Subversive which is installed in the new workspace.
