Jenkins 和 Git 稀疏结帐

Jenkins and Git sparse checkouts

提问by Pavel Chuchuva

I have a large repository in Git. How do I create a job in Jenkins that checks out just one sub-folder from the project?

我在 Git 中有一个大型存储库。如何在 Jenkins 中创建一个仅从项目中检出一个子文件夹的作业？

Jenkins Git Pluginsupport sparse checkoutssince git-plugin 2.1.0 (April, 2014). You will need git >= 1.7.0 for this feature. It is under "Additional Behaviors" -> "Sparse Checkout paths."

自 git-plugin 2.1.0（2014 年 4 月）以来，Jenkins Git 插件支持稀疏结帐。您将需要 git >= 1.7.0 才能使用此功能。它位于“其他行为”->“稀疏结账路径”下。

You can use sparse checkoutfeature of Git. Note that Git still clones whole repository to local disk. That's not too bad however, because it is compressed.

您可以使用Git 的稀疏结帐功能。请注意，Git 仍然会将整个存储库克隆到本地磁盘。然而，这还不算太糟糕，因为它被压缩了。

1. Create a new job in Jenkins, set Git repository in Source Code Management section.
2. Build the project. This will clone whole repository to local disk.
3. Open projects's workspace folder, delete everything there except .git folder.

4. Open Git shell for project's workspace folder. Enable sparse-checkout:

   git config core.sparsecheckout true
   

5. Update working tree:

   git read-tree -mu HEAD
   

6. Create sparse-checkoutfile in .git/info folder. Add path to sub-folder you want to checkout to that file, like so (note trailing slash):

   folder/to/include/
   

7. Build the project again. This time only one sub-folder should appear in workspace folder.

1. 在 Jenkins 中创建一个新作业，在 Source Code Management 部分设置 Git 存储库。
2. 构建项目。这会将整个存储库克隆到本地磁盘。
3. 打开项目的工作区文件夹，删除除 .git 文件夹之外的所有内容。

4. 打开项目工作区文件夹的 Git shell。启用稀疏结帐：

   git config core.sparsecheckout true
   

5. 更新工作树：

   git read-tree -mu HEAD
   

6. sparse-checkout在 .git/info 文件夹中创建文件。将要签出到该文件的子文件夹的路径添加到该文件中，如下所示（注意尾部斜杠）：

   folder/to/include/
   

7. 再次构建项目。这次只有一个子文件夹应该出现在工作区文件夹中。

You could have a custom step that would just use

你可以有一个只使用的自定义步骤

git checkout your-branch -- the/desired/path anthother/desired/path

To clear it you could just rm -rfthe working folder and recreate it with mkdir workingdir. This would require you to specify this option on the git level of the above command:

要清除它，您可以只rm -rf使用工作文件夹并使用mkdir workingdir. 这将要求您在上述命令的 git 级别指定此选项：

git --working-dir="/path/to/workingdir" checkout your-branch -- the/desired/path anthother/desired/path

All this depends on how well you know Jenkins.

所有这一切都取决于您对詹金斯的了解程度。
