We currently are on the latest version of teamcity. We are trying to do a tag based java build. We are wondering what the most efficient way would be to accomplish this in TC? We have about 300 projects that make up our production websphere environment. Each CVS project can have a different tag that needs to be built as a collective. We currently are using background cvs commands to do the checkout and then using at to build them against the appropriate environment. This seems to be taking 30 minutes to checkout the projects where our branch based buidls that use and AmpMod which is a collection of the same amount of projects only takes about 8 minutes.
