Troubleshoot Package Undeployment
Common causes of undeployment failure that are indicated by exception messages are:
• java.lang.NumberFormatException: The version number was not specified.
• java.lang.Exception:
— The package was never deployed successfully.
— The package has already been removed.
— The package name is misspelled, or is not the name assigned to the installed package hierarchy by an annotation in the main class within the JAR file
— You specify an incorrect version number.
— You included the “.jar” suffix, which should be omitted when undeploying a package.
