Hi,
I've been on this list and using Ant since 1.2, and unlike the occasional
poster to this list that complains about the quality of the Ant docs, I
always thought the were outstanding for an open source project. That is,
until I decided to start using <available> in my build files.
I can't figure out how to use this task in conjunction with the <fail>
task to abort the build if a resource isn't available, because the
<fail> task in 1.4.1 doesn't support the "if" or "unless"
attributes.
I'm sure I'm missing something.
Consider the case where a class, Foo, must be available for a particular
build to succeed. I have the following two targets in my file:
<target name="verify"
description="Verifies that all prequisite elements are deployed">
<!-- The Foo class must already be deployed -->
<available
classname="edu.calpoly.dept.group.project.Foo"
classpathref="deployment.class.path"
property="foo.class.present" />
</target>
<target name="stage"
depends="verify"
unless="foo.class.present">
...
</target>
...when I, by hand, deleted the file Foo.class, Ant still attempts to
invoke the 'stage' target even though the property 'foo.class.present'
shouldn't be set.
Is there some way I can use the <fail> target to make the build fail
if Foo.class isn't available? Thanks in advance for any help you can
offer.
Bill
