Unable to set pod retention for Jenkins Kubernetes plugin Groovy script.

[santhosh kumar]

Trying to configure pod retention value  for Jenkins Kubernetes plugin using
groovy script.
kubernetes.setPodRetention(org.csanchez.jenkins.plugins.kubernetes.pod.retention.Podretention.Never())
method is failing to configure with below error :

Invalid value provided in main configuration No signature of method: static
org.csanchez.jenkins.plugins.kubernetes.pod.retention.PodRetention.Never()
is applicable for argument types: () values: []

tried configuring by using different values for the method:
kubernetes.setPodRetention(org.csanchez.jenkins.plugins.kubernetes.pod.retention.Never)

Error using the above value as well.

Please some one help me on this as i was struck with this from quite a long.

Below is the code:

KubernetesCloud kubernetes = new KubernetesCloud('test')
kubernetes.setServerUrl('http://test_url')
kubernetes.setMaxRequestsPerHostStr(20)
kubernetes.setPodRetention(org.csanchez.jenkins.plugins.kubernetes.pod.retention.PodRetention.Never())
kubernetes.setWaitForPodSec(90)

// documentation reference

 https://javadoc.jenkins.io/plugin/kubernetes/

// Method used

Set the global pod retention policy for the plugin.

Can some let me know how to set the pod retention value using groovy with setPodRetention
