Subject RE: Looking for a Build Philosophy

Good question. Here's what I just did on my last project:

As technical lead and the only person who had used ant and our Source Code Management system
before, I ended up taking on the role of build manager. By the end of the project, when I
had to hand off to the maintenance team, I was quite enjoying it.

I would start each day by bringing in the latest work checked into the SCM (CM Synergy from
Telelogic). I would then compile the entire project using "ant clean build", which would compile
everything and build our output WAR file. We didn't use any EJBs, so we didn't need to go
to the effort of building an EAR file. If the project built successfully (including running
junit tests and XML configuration file validations) then the new work was Integrated and made
available for the development team. I would repeat this process after lunch and on an ad-hoc
basis if required.

One interesting thing we did for fun, was to specify that anyone who broke the build was required
to bring in treats for the team the next day (Bagels and Cream Cheese was the most popular
treat). This is a wonderful motivator ... in fact we had to start buying treats for wacky
and offbeat reasons as I think that we broke the build less than a handful of times in about
four months! (Nice problem to have! :-)

On a philosphical note, to me, any project that cannot be compiled at a moments notice has
a problem. By compile, I mean the integration build. Obviously, developer workareas are unbuildable
during editing sessions.

Testing was big for us, but I think on future projects testing will be BIG BIG BIG! We used
Junit and Jtest! (from my good friends at Parasoft) and these two tools saved us much pain
and wailing and gnashing of teeth.

Hope that this helps.

Simon
