Jenkins and Git info/sparse-checkout

Question

I have very large repository in Git and I have created a job in Jenkins that checks out just one sub-folder from the project following this steps Jenkins and Git sparse checkouts. The problem is that when i or some of my colleagues Wipe Out Current Workspace from Jenkins, info/sparse-checkout gets deleted too.

How can i fix this issue without having to create info/sparse-checkout every time for the same job?

Answer 1

I think it is currently not possible with the git plugin alone (maybe you extend it).

I see these two possible solutions:

• You use a plugin (EnvInject+Plugin or pre-scm-buildstep) to execute a shell-script before the SCM checkout. The script have to look like apenwarrs answer.

• You have a task in Ant/Maven/Grunt/Whatever, which setup the sparse checkout (what I currently do). Setup your Job as usally and execute the new task before all others.

Answer 2

According to this Jenkins support ticket it's a recent addition. As I am currently working through this I will try to remember to update on my progress.

[edit] To clarify - Git Sparse Checkout in Jenkins is apparently supported via Jenkins Plugin as of 31/Mar/14. I have no experience with this plugin to say that it works. However, I am hoping to add this plugin to our Jenkins system soon and report back on its success.
