| * This provider uses the following strategy to discover the committer and author name/mail for a commit: |
| * <ol> |
| * <li>"user" section in .gitconfig</li> |
| * <li>"username" passed to maven execution</li> |
| * <li>default git config (system user and hostname for email)</li> |
| * </ol> |
| * the "maven-scm" config can be configured like this: <br> |
| * the default email domain to be used (will be used to create an email from the username passed to maven):<br> |
| * <code>git config --global maven-scm.maildomain mycomp.com</code> <br> |
| * you can also enforce the usage of the username for the author and committer:<br> |
| * <code>git config --global maven-scm.forceUsername true</code> <br> |
