David,
Thank you. I am using the contrib var task. That is the one where I am seeing
scoping constraints. What I am now programming is a variable that is set and
checked.
module list is defined in a property file.
<target name="top_level">
<var name="been_here" value="false"/>
<for list="${modules} param="this_module" trim="true"/>
<sequential>
<antcall target="__compile_module">
<param name="module" value="@this_module">
</antcall>
<var name="been_here" unset="true"/>
<var name="been_here" value="true"/>
</sequential>
</for>
</target>
<target name="__compile_module">
generate file name and store it in the variable this_file. Call any required
targets then: <antcall target="__build_file_list"/>
</target>
<target name="__build_file_list">
<if>
<equals arg1="${been_here} arg2="true"/>
<then>
<echo file="the_file.prop">,${this_file}</echo>
</then>
<else>
<echo file="the_files.prop">file_list=${this_file}</echo>
</else>
</if>
</target>
At the end of the build, I use loadproperties to load the_files.prop. Then I
iterate through the file_list and add the zip file comment to each of the files.
I was hoping for an easier way to do this, but I have something workable.
Thank you,
Chuck Holzwarth

Subject: Re: Variables and zip file comments
You cannot reset the value of a property. They are not variables
because
they don't vary. Once you set the value of a property, you cannot
change it.
There are a couple of ways to handle what you want:
* Use <antcall> or <macrodef>. These allow you to pass parameters that
will
set properties inside the calls. See the example below.
* Use the AntContrib's variable task. This (unlike <properties> is a
true
variable.
See http://ant-contrib.sourceforge.net/tasks/tasks/variable_task.html
Here's how to use <antcall> to be able to change the comment.
<macrodef> is
very similar:
<target name="main">
<antcall target="ziptask">
<param name="zipComment" value="Comment #1"/>
<param name="zipDir" value="mydir1"/>
<param name="zipName" value="zip1.zip"/>
</antcall>
<antcall task="ziptask">
<param name="zipComment" value="Comment #2"/>
<param name="zipDir" value="mydir2"/>
<param name="zipName" value="zip2.zip"/>
</antcall>
</target>
<target name="ziptask">
<zip destfile="${zipName}"
basedir="${zipDir}"
comment="${zipComment}"/>
</target>
