You may see this or a similar issue when trying to publish to a Nexus Release repository from Studio:
The Nexus Release repository has a setting that prevents redeployment. This prevents the same version of a Job from being published. This setting can be found in Releases > Configuration > Deployment Policy.
There are two possible solutions:
Change the Deployment Policy value in Nexus to Allow Redeploy.
Under Acess Settings, change the Deployment Policy to Allow Redeploy:
It's always advisable (though not required) to deploy or redeploy Jobs in Snapshot, and when the final build is ready, then deploy it to Releases.
