Well, Ant has no built-in bootstrap mechanism. Build scripts are typically under version control, but they might use support files (typically imported) from other modules of the VCS, and they might use JARs downloaded from somewhere or under VCS themselves. If you run checks to verify for new versions of files/JARs implicitly on every build, you run the risk of slowing down all builds, and surprising your users for changes they didn't want, so I find it nicer to have an explicit target(s) to do the checking and updating explicitly. But even that can fail, especially on Windows, since you can't update JARs ANT is currently using, and you can't easily force ANT to use a new version of a JAR that was just updated. I believe that bootstrapping is possible, but I think it would require changes in Ant to possibly restart a new VM using new JARs for example, or at least rerun itself into a completely different class loader (and a way to update JARs already in use on Windows). Didn't do it myself. --DD --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@ant.apache.org For additional commands, e-mail: user-h...@ant.apache.org
