Store Subversion credentials in Maven

When you are using Subversion from the command line instead of via a tool like TortoiseSVN, then you do NOT want to provide your username and password everything again when you want to update or commit the code of your Maven project.

To ensure that your SVN never asks for the credentials again, you can set these in your settings.xml via below addition.

The ID needs to be the host of your Subversion repository. So, when your Subversion url is “″, then the id is “”.



An example of an error from the maven-release-plugin when the [proper] SVN credentials are not available.
