I'm receiving this error when trying to run a Jenkins Job. The file configuration seems to be valid. What steps should I take to troublshoot this issue?
Problem: failed to create task or type antlib:com.salesforce:deploy
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet
This appears to be an antlib declaration.
Action: Check that the implementing library exists in one of:
-a directory added on the command line with the -lib argument
