best way to create an empty patternset?

[Jay Dickon Glanville <di...@gmail.com>]

Hello all.

What's the best way to create an empty patternset (that is, a pattern
set that will result in no inclusions)?

Why on earth would I want such a thing?  I have two common tasks
(compile and deploy) that are repeated for several applications.
Because of this repetition, I've created two <macrodef>s.  Both of
these take a patternset as an attribute (the first macro uses it in a
classpath, and the second copys all jars into a staging area).
Therefore, a patternset needs to exist for all applications that use
these macros.

One of my applications doesn't have any jar dependencies.  So, I need
an empty patternset so that nothing is included in the classpath or
copied to the staging area.

Any suggestions?

Thanks

PS: I'm using Ant 1.6.5 due to some other limitations.

Any pattern with a non-sensible-enough name will do. I tend to use one
that documents what I'm doing. For example, in your case, <patternset
includes="- no dependencies -" />. It's quite unlikely to have a file
named "- no dependencies -" in the filesystem. --DD
