JGit API是否具有所有Git命令？ [英] Does JGit API have all Git commands

问题描述

我试图将一个shell脚本移植到Java中，该脚本包含几个我在JGit API中可以找到的Git命令。然而，我没有找到远程命令或命令，这是因为它不存在，或者我只是在错误的地方寻找它们。如果它们不存在，是否有另一种方法来使用它们？

解决方案

没有准备好的对应于<$在JGit中c $ c> git remote 和 am ，但应该可以通过合理的努力来实现它们的一部分。 p>

查询或操作配置文件的那些 git remote 子命令可以通过直接访问存储库配置来模拟 Repository.getConfig（）。

清理过时的远程追踪分支，如 git remote prune 可以，您可以使用 LsRemoteCommand 来获取现有远程分支的列表，并从本地配置中删除不匹配该列表的远程。 / p>

替换 git am 可能会更加努力。有一个 ApplyCommand 来应用来自给定输入流的补丁以及低级 Patch 类来解析diff文件。剩下的就是解析邮箱文件，并从包含的差异和元数据（消息，作者等）中产生提交。

I am trying to port a shell script to Java which contains a few Git commands which I have mostly managed to find in the JGit API. I have not, however, managed to find the remote or am commands, is this because the don't exist or I am just looking in the wrong place for them. If they don't exist is there another way to use them?

解决方案

There is no ready-to run counterpart for git remote and am in JGit, but it should be possible to implement (a subset of) them with reasonable effort.

Those sub-commands of git remote that query or manipulate the config file can be emulated by directly accessing the repository configuration through Repository.getConfig().

To clean stale remote-tracking branches like git remote prune does, you can use LsRemoteCommand to obtain a list of existing remote branches and remove remotes from the local configuration that do not match that list.

Replacing git am might be a little more effort. There is an ApplyCommand to apply a patch from a given input stream as well as the low-level Patch class to parse diffs. What would be left is to parse the mailbox files and produce a commit from the contained diffs and meta-data (message, author, etc.).
