An error occurred (400 Bad Request)
java.io.IOException: Transfer to /org/example/WebService/0.1.0/WebSerivce-0.1.0.zip failed 400 Bad Request

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.

   2. Select Views/Repositories > Repositories.
   3. Open Releases.
   4. Select Configuration.

   5. 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.
