How to determine the current operating system in a Jenkins pipeline

What would be the way to determine the current OS a Jenkins pipeline is running?

Context: I'm building a shared Jenkins pipeline script that should run on all platforms (windows, OSX, linux) and execute something different in each platform.

I tried something like:

import org.apache.commons.lang.SystemUtils

if (SystemUtils.IS_OS_WINDOWS){
   bat("Command")
}
if (SystemUtils.IS_OS_MAC){
   sh("Command")
}
if (SystemUtils.IS_OS_LINUX){
   sh("Command")
}

But even it is running on windows or mac node it always goes into the SystemUtils.IS_OS_LINUX branch

I tried a quick pipeline like this. 

node('windows ') {
     println ('## OS ' + System.properties['os.name'])
}
node('osx ') {
     println ('## OS ' + System.properties['os.name'])
}
node('linux') {
     println ('## OS ' + System.properties['os.name'])
}

Each node get correctly run in a machine with the correct OS but all of them print ## OS Linux

any ideas?

Thanks Fede

Solution

  • As far as I know Jenkins only differentiates between windows and unix, i.e. if on windows, use bat, on unix/mac/linux, use sh. So you could use isUnix(), more info here, to determine if you're on unix or windows, and in the case of unix use sh and @Spencer Malone's answer to prope more information about that system (if needed).
