Dean,
We use a few generic builds for many apps on NT. The following
summarizes the approach.

1.   My ide and ant share the application source directories.

1a  In the root directory of the source, i put a properties file
      that contains options used by the build, e.g. where the output
      goes, what extensions are needed to permit compilation, etc.
      This property file is what permits the central ant builds to be
      generic with respect to applications.

2.  The ide is used to change code and get clean compiles.

3.  A few, centrally controlled ant builds are used to create and
     deploy jar, ear, war, and zip files for all projects.
     Only when developing a desktop client do we actually execute
      the ide-generated class files, and that's just while testing. In
      production all executables are in jars.

4.  On the NT execition path, I have an nt bat file (runMyBuild)
     that starts a central build.

5.  I position the NT command window to the shared source
     directory and manually execute runMyBuild. Recently I've switched
      to starting ant from my IDE (intellij idea), in which case a generic,
      minimal, proxy ant build takes over the role of runMyBuild, i.e.
      launching a central build script.

6. runMyBuild copies the central ant build file into the current
    (source) directory and calls ant to do the build. During execution,
    the build references the property file stashed in the source root.

7. When ant is finished, runMyBuild deletes the copied build file from
    the source directory, so that build files dont lie around to be evolved
    ad hoc.

Hope this helps,
Bill.
