本文整理了Java中org.eclipse.jgit.api.Git类的一些代码示例，展示了Git类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Git类的具体详情如下：
包路径：org.eclipse.jgit.api.Git
类名称：Git

Git介绍

[英]Offers a "GitPorcelain"-like API to interact with a git repository.

The GitPorcelain commands are described in the Git Documentation.

This class only offers methods to construct so-called command classes. Each GitPorcelain command is represented by one command class.
Example: this class offers a commit() method returning an instance of the CommitCommand class. The CommitCommand class has setters for all the arguments and options. The CommitCommand class also has a call method to actually execute the commit. The following code show's how to do a simple commit:

Git git = new Git(myRepo); 
git.commit().setMessage("Fix393").setAuthor(developerIdent).call();

All mandatory parameters for commands have to be specified in the methods of this class, the optional parameters have to be specified by the setter-methods of the Command class.

This class is intended to be used internally (e.g. by JGit tests) or by external components (EGit, third-party tools) when they need exactly the functionality of a GitPorcelain command. There are use-cases where this class is not optimal and where you should use the more low-level JGit classes. The methods in this class may for example offer too much functionality or they offer the functionality with the wrong arguments.
[中]提供一个类似于“GitCellar”的API来与git存储库交互。
GitCellar命令在Git Documentation中描述。
此类仅提供构造所谓命令类的方法。每个命令由一个命令类表示。
示例：此类提供了一个commit（）方法，返回CommitCommand类的实例。CommitCommand类具有所有参数和选项的设置器。CommitCommand类还有一个调用方法来实际执行提交。下面的代码演示了如何执行简单的提交：

Git git = new Git(myRepo); 
git.commit().setMessage("Fix393").setAuthor(developerIdent).call();

命令的所有必需参数必须在此类的方法中指定，可选参数必须由命令类的setter方法指定。
当外部组件（EGit，第三方工具）需要git命令的功能时，该类用于内部（例如通过JGit测试）或外部组件（EGit，第三方工具）。在某些用例中，这个类不是最佳的，您应该使用更低级的JGit类。例如，此类中的方法可能提供了太多的功能，或者它们提供的功能带有错误的参数。
