kite-maven-plugin:package-app fails with IllegalArugmentException when applicationName is anything other than the default value.
Caused by: java.lang.IllegalArgumentException: Parameter 'directory' is not a directory

"outputDir" refers to a directory that does not exist due to incorrect configuration of the maven-assembly-plugin. When changing the applicationName, the assemblyPlugin needs "finalName" = applicationName and "appendAssemblyId" = false such that it will create the output in the expected "outputDir".
If this issue is corrected, deploy-app also fails with a non-default applicationName unless "localApplicationFile" is overridden. A trivial change can be made to correct that problem as well.
I'm not sure how exactly you prefer to receive contributions, but I could provide a pull request with the changes to fix both of these issues.
