Jenkins : how to check out artifact from Nexus and Deploy on Tomcat-

I am tying to set up a Jenkins Pipeline. The first stage is done, the code compiles, is tested, inspected and deployed to Nexus.

I would like now to make a second stage on the pipeline where the war is checked out from Nexus and deployed on tomcat.

Actually I already integrated the maven-tomcat plugin to deploy on Tomcat. My question is how can I check out the latest build of the war ?

Is there any maven or jenkins plugin for that ?

Many thanks,

Patrick
