SCM plugins are what help integrate version control services. They provide the following:
- Allow Jenkins to run version control systems such as Git, Mercurial, and SCM.
- Allow Jenkins to pull code from version control hosts, such as GitHub, Bitbucket, GitLab, and so on.
- Authenticate Jenkins to pull from both private and public version control hosts.
The points we have listed here are not the full potential of the plugin types. The possibilities are infinite.
