Install a cvs client e.g. cvsnt
Drop the war file in tomcat (I'm using v7)
Add 'set "HUDSON_HOME=d:\HUDSON"' to tomcat's startup.bat. This is where all the build configurations and workspaces are saved so there needs to be enough space.
Start Hudson and install the recommended plugins
Install plugins: Manage Hudson->Plugins. Need MSBuild, CVS, CVS-Tag
Create a job
My approach is to debug and test the application locally. Only when I want to create a preview/stage or production version do I need Hudson. Hudson should do a build and publish. When successful, a new CVS tag should be created.
The following job settings do not contain any deploy location information (stage/prod). The job always publishes to a temp location on D:. I want to change this later.
