Pre-build task - deleting the working copy in CruiseControl.NET

Question

I\'m currently in the process of setting up a continuous integration environment at work. We are using VisualSVN Server and CrusieControl.NET. Occasionally a build will fail

Answer 1

@jamie: There is one reason why you may not be able to do a clean build every time when using a continuous integration server -- build time. On some projects I've worked on, clean builds take 80+ minutes (an embedded project consisting of thousands of C++ files to checkout and then compile against multiple targets). In this case, you have to weigh the benefit of fast feedback against the likelihood that a clean build will catch something that an incremental build won't. In our case, we worked on improving and parallelizing the build process while at the same time allowing incremental builds on our CI machine. We did have a few problems because we weren't doing clean builds, but by doing a clean build nightly or weekly you could remove the risk without losing the fast feedback of your CI machine.
