JGit：找不到教程或简单的例子 [英] JGit: Cannot find a tutorial or simple example

问题描述

我找不到JGit的工作教程。

I cannot find a working tutorial for JGit.

如果任何人有一个很好的链接或一个简单的例子（f.ex. cat-a -file）（如何cat一个文件的答案JGit？不能用JGit V.1.0编译）

It would be very helpful if anyone has a good link or a simple example (f.ex. cat-a-file) that works (The answer from How to "cat" a file in JGit? doesn't compile with JGit V.1.0).

不幸的是，官方的 JGit文档对我来说不是很有用。但是我认为使用JGit的开发人员必须很多。

Unfortunately the official JGit documentation for beginners is not very useful to me. But I think there must be a lot developers who are using JGit?

推荐答案

事实上，使用API​​。

Indeed, there is very little around in terms of documented usage of the API.

为了其他读者的意图，我特此为最常见的操作提供简单的测试：

For the sake of other readers, I hereby provide a simple test for the most common operations:

1. 创建存储库


2. 克隆它


3. 添加文件

<将

4. 推送


5. 跟踪 origin / master into 主人（如果你克隆了一个裸的回购，这是必要的）


6. 拉（在这种情况下，无论如何，无论如何）

1. Create the repository
2. Clone it
3. Add a file
4. Commit
5. Push
6. Track origin/master into master (this is necessary if you clone a bare repo)
7. Pull (uselessly, in this case, but whatever)

特别要注意，添加文件需要模式，而不是路径。此外，由于克隆中存在 master ，跟踪需要 .setForce（true）。

In particular, note that adding files requires a pattern, not a path. Also, tracking requires .setForce(true) due to the existence of master on the clone.

请考虑这个例子是简单和自包含的。

Please consider that this example is meant to be simple and self-contained.

import java.io.File;
import java.io.IOException;

    @Test

    @Test
