The plugin uses the revision number to identify changes. ( SONARPLUGINS-854 )
But the clearcase changelog command doesn't provide this information. ( SCM-619 )
I hope this can be corrected by the next scm version.
[patch] Add revision number in changelog clearcase command.
Stop using the changelog/revision to determine if the blame information should be updated on a source file
Revision number cannot be aggregated up to project level for some VCS
