When using the perforce plugin we often get the error message below during
synchronization with the perforce workspace.

Our work around is then to try building again with the latest synced change list
in field "First Changelist to Track" of the project configuration, in the case
below this field should be set to "12140". It would be nice if we would not have
to use the workarounds: if we could return to single click building.

Error message:
