I am trying to setup sh command as part of my Jenkins pipeline. This command has one parameter where list of values is supplied. Those values have spaces in them.

I have tried so many things, arrays, escaping etc etc none worked.

Here is an example:

# In Jenkins task I configure env variable:
VALUE_LIST=("Value One" "Value Two" "Value Three")

# In pipeline:
sh "command --param ${env.VALUE_LIST[@]}"

Please understand that this is only one of the ways I tried to make this work.

I need the result command to look like:

command --param "Value One" "Value Two" "Value Three"

Best I could achieve was

command --param Value One Value Two Value Three

Which obviously does not work

    My question is, how do I create this command that will work as expected – Tomas Feb 2 '17 at 12:18
  • have you tried single quotes 'instead of double quotes? – Michael D. Feb 2 '17 at 12:20
  • Yes, I honestly tried pretty much anything I could find... sh ' comand --param '"${env.VALUE_LIST[@]} no luck – Tomas Feb 2 '17 at 12:23

This should work.

printf "%s\0" "${VALUE_LIST[@]}" | xargs -0  sh -c 'command --param "$@"' command_name

Print the values to xargs and use null as delimiter. Then xargs calls sh and sh executes the command with the values as arguments. The last piece, command_name, will represent the command by the name you provide. It is obligatory in this construct, as otherwise command will not receive the first value form the list "$@".

  • It did work as expected, but still didn't work in pipeline due to the command it self.. There is some bug in it, I reported it. Fortunately the command accepts parameters in different formats, one of which is JSON and I managed to get it work with that. – Tomas Feb 8 '17 at 10:26
