target conditional and dependency issue

[Eric Wood <EW...@llbean.com>]

I have a target that I only want to execute if a property is set, but it
executes the dependencies regardless.  
The code looks like this:
 
    <target name="cruisecleanup" depends="init, clean, prepare,
_cruisecleanup" if="cruise.logs.dir" />
 
What I have used as a work around is:
 
    <target name="cruisecleanup" depends="" if="cruise.logs.dir" />
       <runtarget target="run-cruisecleanup">
    </target>
 
    <target name="run-cruisecleanup" depends="init, clean, prepare,
_cruisecleanup" />
 
This works, but it doesn't seem very ANT like.  Do folks have a better,
way to perform the conditional execution with a dependency list?
 
Thanks, Eric

Yes, the dependencies to get hit before the test is done. There's a
reason for that:


<target name="foo"
    depends "foo-test"
    if='foo-test-passes"/>

<target name="foo-test">
<condition property="foo-test-passes"
     <some condition>
</condition>

This allows me to run my target "foo", but only if I pass the
"foo-test". Otherwise, there would be no easy way to run a target
based upon a more complex condition than whether a particular property
is set or not.

Your work around is pretty much the way to make sure that you don't
run dependencies if the target is not suppose to be executed.
