Due to security concerns we have two Jenkins instances, One that lives in a secure area and only deploys jars that have been built (cannot connect to GIT). The other lives outside the really secure area and builds the jars. The JenkinsBuild instance builds from GIT and then pushes the jar to an FTP server where a script copies the jar to the correct project workspace in the JenkinsDeploy instance.
Is there a way for Jenkins to see a change in the workspace (new jar)and auto deploy the latest jar? Or would I have to get the script that copies the jar to the workspace to trigger the build (with parameters)? I have admin privileges in Jenkins but I can't modify the script myself.
