Reproduction steps

steps { ansiblePlaybook( extraVars:[ var1: 'test', var2: ['test1', 'test2'] ]) }

Expected Results

Should override the variables in inventory at run time.
[Pipeline] ansiblePlaybook [tag1] $ /usr/bin/ansible-playbook myPlaybook.yml -i inventory -l host1 -t tag1 -b --become-user root -e ******** -e ********

Actual Results

Anything else?

Tried degrading jenkins ansible plugin versions, earlier worked with the latest version I'm currently using.
The playbook works just fine when extra vars are passed through command line.
