Jenkins: send multiple params in URL trigger - jenkins

Question

I have a Jenkins job which checks a file version...
This project is parameterized:
Multi-line String Parameter = server
Powershell command
$servers = ($env:servers).Split([Environment]::NewLine, [StringSplitOptions]::RemoveEmptyEntries)
foreach ($server in $servers) {ls "\\$server\c$\update.dll" | % versioninfo}
I trigger it using the URL:
http://MY_JENKINS_SERVER/job/FILE_VERSION/buildWithParameters?servers=10.10.10.1
it works and I get:
ProductVersion FileVersion FileName
-------------- ----------- --------
11.1.1.16 11.1.1.16 \\10.10.10.1\c$\update.dll
But I want to send multiple IP's in the trigger URL, eg
10.10.10.1
10.10.10.2
10.10.10.7
So I output something like:
ProductVersion FileVersion FileName
-------------- ----------- --------
11.1.1.16 11.1.1.16 \\10.10.10.1\c$\update.dll
11.1.1.15 11.1.1.15 \\10.10.10.2\c$\update.dll
11.1.1.15 11.1.1.15 \\10.10.10.7\c$\update.dll
Anyone know how?

Since you are using "Multiline String Parameter", you will have to provide all the required values separated by newline character. Generally, \n is considered for newline, however, you will have to "url-escape" it. Use this %0A as newline character.
So, your POST URL should be something like this :
curl -v -X POST <jenkins_url>/<job_name>/buildWithParameters?server=11.1.1.16%0A11.1.1.15%0A11.1.1.15
