Be careful when downloading stuff.

ArgoUML is supposed to be a self-contained development environment. Some times it is better to have things downloaded from the ant script instead of from the repository. In that case separate the download-targets from the target that does building so that it is easy for everyone to know when their development machine is working against the Internet and when it is not.

Public targets shall have descriptions. Non-public targets shall not have descriptions (write xml comments or echos instead).

Use ant-built-ins for everything.

ArgoUML is supposed to be a self-contains development environment. If you feel tempted to use other tools (perl, sed, nsgmls), don't! They are probably not present in all environments where we want to run a development environment.
