Administration	Git

In the git section there are the following git specific settings:

• GC Cron Expression

  If this is set, SCM-Manager will execute a git garbage collection matching the given cron expression.

• Disable Non Fast-Forward

  Activate this to reject forced pushes that are not fast forwards.

• Default Branch

  The branch name configured here will be used for the initialization of new repositories. Please mind, that due to git internals this cannot work for empty repositories (here git will always use its internal default branch, so at the time being master).
