[kepler-dev] Add depency in build.xml?

[Matt Jones]

Jing,

Ant has the ability to prompt for input.  Matthew has used this feature 
in the JUnit tests in utilities -- check that for an example.  So you 
should be able to construct the CVSROOT from a userid that you either 
get from user input or from the environment (for example, from $USER or 
$CVSROOT environment vars). That way the developer does not have to edit 
build.xml, and the account will change to the right CVS account.

As to whether or not we should include the checkout in the build 
process, I think we should.  Everyone that has CVS access to kepler has 
CVS access to seek, and the costs of duplicating code and having it be 
out of date is high.  THat is why we have the development guideline in 
the Kepler development guidelines:
   4. Try to not check in files that can be generated from the build system

I think your approach follows this guideline well.
