automated release process

I need to use some version system and make a automated release .

Can you suggest some preferable open source software'开发者_如何学编程s to use and are efficient.

And how does a automated release go..

Hudson can be a good start (not just for release management but for any task you want to automate).

• It does integrate well with most VCS out there.
• It has several plugins related to Release Management like:
  • Subversion Release Manager
  • M2 Release Plugin (allowing you to perform a release build using the maven-release-plugin from within Hudson)

CruiseControl (Java, .NET). Also see Continuous Integration Tools.
