Using TeamCity build templates how can I remove "Clean all files before build" from the template?

Question

I have a number of daily and in-response-to-svn-change builds that all derive from the same configuration template. I can set it so I can choose what branch to look at, what build steps to carry out and of course what triggers the build.

However I would like the daily builds to do a completely clean checkout, whereas the svn dependent ones (that obviously happen throughout the day) I am happy for them to simply to an update.

Simply un-setting the option in the template does not let me set them in each of the derived builds. Is there a build parameter that I can use to switch on clean builds for those builds that require it?

Answer 1

In each Project's "Version Control Settings", look under "Checkout setting". There are options to specify the checkout dir and also a checkbox to clean files before a build.

Answer 2

There is an Additional Build Feature (Swabra) you can add that does a clean checkout if required.I have enabled this for our nightly builds but have not yet investigated the consequences.
