Sharing files between jenkins master and slave nodes - powershell

Question

# test.ps1
function foo {
echo "bar"
}
I have a file named test.ps1 which contains some frequently called functions. And I want it to be shared between my jenkins master and slave nodes.
I've tried creating 2 copies of test.ps1 and put them in master and slave nodes. But this is not convenient. Because I'll have to maintain 2 test.ps1s
Another way I've tried is putting 1 test.ps1 at master node and copying test.ps1 from master to slave with Publish Over SSH Plugin whenever I need to use test.ps1 at slave node. This is not convenient, either.
How can I share test.ps1 between master and slave nodes?

Answer 1

I found that Config File Provider Plugin solves my problem:
First, create a custom file using this plugin:
Write the name and content of this shared file. Then save it.
Inside your project, check Provide Configuration files
Jenkins will create test.ps1 inside Target folder (In my case, I set it to the workspace of the project) whenever you build the project. Note that this folder must exist before building the project.
Variable represents an environment variable with which you can refer to the file test.ps1.
Inside your build step, you can import the file using . $env:util. Then you will be able to call the function foo.
The above can be done no matter whether you are at master or slave node.
