I am using JIRA Cli from Bob Swift. When i try to clone a project with cloneProject it succeeds but i expected the issuenumbers to be the same in the cloned project. Is this possible? Can Bob Swift answer if he's around? 
eg:
java -jar jira-cli/lib/jira-cli-5.5.0.jar --server $JIRA_SERVER --user $JIRA_USER --password $JIRA_PASSWORD \
--action cloneProject --project $PROJECTKEY --toProject $NEW_PROJECTKEY --name "$NEW_PROJECTNAME" --cloneIssues \
--continue --verbose
now FOO-1 is not the same issue as BAR-1, FOO-2 is not the same issue as BAR-2 and so forth.
Edit: The original project had lots of subtasks which are now deleted so FOO-2 to FOO-6 does not exist, so the skew appears whenever a issuekey is not avaible in sequence in the first project.
eg.
FOO-1 > BAR-1
FOO-2 to FOO-6 does not exist so FOO-7 is then BAR-2..
