Jenkins and Git: Monitor specific folder on any branch
提问by JaSn
My repo has multiple projects in subfolders with same structure duplicated across multiple branches.
我的 repo 在子文件夹中有多个项目，在多个分支中复制了相同的结构。
I'm trying to set up a job that monitors all branches and triggers a job only when a change in a subdirectory 'Project1' is made. This way I can check if changes to 'Project1' work on release branches and any dev branches people might set up.
我正在尝试设置一个作业来监视所有分支并仅在子目录“Project1”中进行更改时才触发作业。通过这种方式，我可以检查对“Project1”的更改是否适用于发布分支和人们可能设置的任何开发分支。
In theory it seems the Git plugin does let me set this up, by specifying '**' in 'Branches to build' and 'Project1.*' in 'Included Regions'. I also use 'Poll SCM' since that seems to be a prerequisite.
从理论上讲，Git 插件似乎确实让我通过在“要构建的分支”中指定“**”和“包含区域”中的“Project1.*”来进行设置。我也使用“Poll SCM”，因为这似乎是一个先决条件。
This works fine as long as you make changes only to one branch. Once you make a change outside of the 'Project1' folder on another branch, Jenkins picks up a changes from any directory.
只要您只对一个分支进行更改，这种方法就可以正常工作。一旦您在另一个分支上的“Project1”文件夹之外进行更改，Jenkins 就会从任何目录中获取更改。
Is this a bug or am I trying to do something that is not supported?
这是一个错误还是我试图做一些不受支持的事情？

It`s possible, but not recommended. You can set additional checkout behavior and then choose which folders should trigger the build and which are not.
可以，但不推荐。您可以设置额外的结帐行为，然后选择哪些文件夹应该触发构建，哪些不是。

I think that this answercan help you. You only need to implement the hook with the logic which project to build
我认为这个答案可以帮助你。您只需要使用要构建的项目的逻辑来实现钩子
