JavaGit is a Java API that provides access to git repositories. The goal is to bring the power of git to the Java world as an API that is intuitive for developers new to git and developers who are veteran git users. It is engineered to provide the developer with access to the raw git commands through a command API as well as an object API designed to represent the .git repository, the working tree, and other familiar git concepts. JavaGit uses the git binaries installed on the host machine to provide git functionality, and has been designed to easily accommodate additional methods of access to git repositories.
