Add a global or plan repository. If both a name and repository are provided, the name will be used for the Bamboo name and repository will be used for the Bitbucket repository. For a plan repository, you can reference a linked (global) repository. Otherwise a valid repository key or alias is required. Valid aliases are: BITBUCKET, BITBUCKET_CLOUD, BITBUCKET_SERVER, STASH, BCVS, GIT, GITHUB, MERCURIAL, PERFORCE, SUBVERSION. If the credentials parameter is provided the appropriate fields will be added automatically for GIT, Mercurial, and Bitbucket Cloud repositories.
