Hi all,
I was banging my head against the wall for several hours today on this
problem and came up with a tolerable solution. But I thought I would ask to see
if others might have a better solution.
The situation is: we have a product that can be built to support several
different feature sets. There are properties set (or not) depending on which
features to support. Now a new feature requires some new .jar files which are
not needed by any other feature. I have a PatternSet with these .jar files
listed:
<PatternSet id="other-jars">
<include name="abc*.jar" if="support.abc"/>
</PatternSet>
Now there is a Copy task that is putting stuff in the installation directory
that looks like this:
<Copy todir="install/lib">
<FileSet dir="lib">
<PatternSet refid="other-jars"/>
</FileSet>
</Copy>
(I'm not doing a copy/paste here, just from memory, so be easy if there are
syntax errors--hopefully you get the drift.)
Now the problem is: if "support.abc" is not defined, the PatternSet is empty
and the FileSet thinks it should copy everything in the source directory to the
target. But what I want is to copy nothing.
So, any thoughts / suggestions as to how to achieve what I want?
Thanks,
~Roger Whitcomb
P.S. Using Ant 1.9.3 if that makes a difference.
