Hey Vladimir, I have thought about this, but since we've started with maven, there was usually more benefit investing in other features than in a build tool transition. For a while continuous compilation worked even with the maven plugin (http://scala-tools.org/mvnsites/maven-scala-plugin/usage_cc.html), although lately it never seemed to work for some reason.
SBT does have some advantages, and Lift is also trying to migrate. I also can't help but like the fact that SBT, just like ESME, has Actions ;-) http://code.google.com/p/simple-build-tool/wiki/CustomActions Hudson integration is a good point you've mentioned, and this is what I was able to find: http://henkelmann.eu/2010/11/14/sbt_hudson_with_test_integration One question: does it make sense to maintain Maven if/when we move to SBT? I guess not. It's nice that you're giving some thought to this, and even better that you've prepared a build file already! It might definitely be beneficial to test out this setup, and I don't consider your mail a spam :) Vassil On Wed, Dec 22, 2010 at 9:50 PM, Vladimir Ivanov <[email protected]> wrote: > Hi all, > > Have you, guys, considered building ESME with Simple Build Tool: > http://code.google.com/p/simple-build-tool/ , at least locally? > > SBT has several pros and cons. > > Pros: > > - Native Scala support -> no Scala plugin > - There is no need to recompile all project files, only changed ones -> more > faster build&run > - Buildfile is written in Scala instead of verbose XML -> buildfile is > shorter > > Cons: > > - SBT is based on Apache Ivy (while it includes Maven repo by default and > can access local Maven repo) > - I have no idea whether integration of SBT with VCS and CI tools is > possible > > Probably many more cons exist > > I managed to build, run tests and run ESME app on jetty with SBT (of course > I was able to perform only minimal testing).
