Check out files from Subversion repository
By checking out files from a Subversion repository, you obtain a local working copy of the repository, which you can edit. After making the necessary changes, you can publish the results by committing, or checking in your changes to the repository.
From the main menu, choose VCS | Get from Version Control.
In the Get from Version Control dialog, click Add Repository Location and specify the repository URL.
Click Checkout.
In the dialog that opens, specify the destination directory where the local copy of the repository files will be created, and click OK.
If you are checking out sources for an existing project, the destination folder should be below the project content root.
In the SVN Checkout Options dialog, specify the following settings:
Revision to be checked out (HEAD or a selected revision).
Whether you need to check out the nested directories.
Whether you need to include the external locations.
Click OK.
RubyMine suggests creating a project based on the sources checked out from version control.
