   • AHave the deployment pipeline checkout the source code and run the build again before deploying.
   • BCopy the JAR to a shared network drive and reference the file path in the deployment pipeline.
   • CStore the JAR in an artifact repository with a unique version identifier and have the deployment pipeline download that version.
