We would like to use the svn revision number also with this. But it doesn't work that way. What happens i believe is, the date and time is set for the build because of this plugin, and then teamcity checkout the new revision of the code, it cannot reset the build date along with revision number. If you use just the revision number (or any teamcity provided options) for build number, then they are refreshed when the system has the required data.
Has anyone came across this problem and fixed it? please let me know.
