Git Client Plugin

The git-client-plugin provides APIs for Jenkins plugins to interact with Git repositories, enabling operations such as fetching, checking out, branching, merging, and tagging. It supports various authentication methods, including username/password and private key credentials for HTTP, HTTPS, and SSH protocols. The plugin can utilize command line Git or the optional JGit implementation, which is a pure Java version of Git, allowing for flexibility in how Git operations are performed within Jenkins.
