maven_artifact comman of ansible is not working in Rundeck - ansible

Question

Objective:
Download the artifact jar from nexus to a Target server. I have already tried an attempt to download the jar via URL and not via maven_artifact, which was successful anyway. But wanted to try with maven_artifact command
Code in playbook:
---
- name: TestOfMavenArtifactCommand
hosts: Target_Server_Where_the_Jar_needs_to_be_downloaded
tasks:
- maven_artifact:
group_id: ab.cdef.group
artifact_id: artifact_name
repository_url: 'https://nexusUrl/repository/maven-snapshots'
dest: /folder/artifact_name.jar
username: user
state: present
mode: 0755
When I run the Rundeck job, it fails. The error is like:
config file = /etc/ansible/ansible.cfg
configured module search path = [u'/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python2.7/site-packages/ansible
executable location = /bin/ansible-playbook
python version = 2.7.5 (default, Jun 11 2019, 12:19:05) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
Using /etc/ansible/ansible.cfg as config file

This appears to be just an indentation error. Try:
tasks:
- maven_artifact:
group_id: ab.cdef.group
artifact_id: artifact_name
repository_url: 'https://nexusUrl/repository/maven-snapshots'
dest: /folder/artifact_name.jar
username: user
state: present
mode: 0755
