We recently upgraded to ClearCase plugin 1.2.1 from a version which is about a year old (sorry not sure the version). The change to lshistory from the whole VOB since the last build means that for large VOBs with a small amount of elements which are interesting to the build this polling activity can take a very long time especially if the job has infrequent changes.

Would it be possible to have an option to use the lshistory -r functionality as it used to be, or alternatively to only poll for changes since the last time it was polled?
