I am using Subclipse (Subversion integration in Eclipse). I now want to change the user credentials in subclipse. How do I do that? That is to login into subversion using another user account.
Delete, or rename, the Eclipse '.keyring' file in Eclipse's configuration folder. This is where the Subclipse SVNKit connector caches your SVN credentials..
[ECLIPSE INSTALL]\configuration\org.eclipse.core.runtime.keyring
If, on the other hand, you're using the JavaHL connector -- or SVN command-line -- then their credentials are stored in the Subversion runtime config folder. Delete or rename the credential file.
On Windows: %APPDATA%\Subversion\auth
On Linux and OSX: ~/.subversion/auth
Sorry about this pig of complexity, for what should be a real version-control system. :-(
