SQL developer is a tool which has nothing to do with any connection relation with SVN repository. The credentials are independent. Please be more specific with your issue/requirement.
You are incorrect. SQL Developer does connect to source control. Please refer to this link to the Oracle documentation for information. In fact it connects to SVN and CVS. So please, before you tell someone that "SQL developer is a tool which has nothing to do with any connection relation with SVN repository" you should be sure be sure of your facts.
I never said SQL Developer does not connect to subversion. I said connection credentials are independent. And OP to be more specific about the issue, better if he posts the error message.
BTW I am sure about the facts, hence, posted a reply to the OP.
For a demo on setting up the configuration, have a look at http://gerardnico.com/wiki/ide/sqldeveloper/svn
When I set up the SVN connection it asks me for credentials to the repository. Our SVN repository is configured to use our windows credentials. When I enter these credentials into the text box in SVN connection window, and click "Test Connection" the connection fails. Specifically it tells me that read access is denied. If I access the same repository via Tortoise SVN using my windows credentials access to the repository is granted and I can read and write files. I will try changing the http-auth-types to negotiate when I am back in the office.
In SQL Developer, go to
Tools > Preferences > Versioning > Web Browser and Proxy --> check the settings.
Tools > Preferences > Versioning > General > Edit subversion configuration file --> check if the proxy settings are configured properly.
The proxy is not configured, but I am not sure why it needs to be. Both servers reside on the inside of our network and do not use our proxy.
I have the same problem :
1) SVN repository is configured to use windows credentials
2) tried both DOMAIN\user_name and user_name
gave me this:
svn: E200015: authentication failed.
Please check the username and password stored in the Subversion connection.
Verify user name, password and URL are valid.
fixed mine :
