Variables and zip file comments

[Chuck Holzwarth <ch...@yahoo.com>]

The builds I do are differential builds. I use svn diff to gather the diffs. The system is composed of several modules. Each module goes into its own zip file. When code is released, the zip files require a comment that contains, among other things, the names of all of the zip files that are part of the release.

I have been trying to set a variable with the list of module file names. The problem I have is that when the target where I set the variable exits, the variable reverts to the previous value. Is there a way to make a variable persistent?

In the mean time, I have been creating a file that contains the zip file comment. I have not been able to insert the comment in the zip file using the zip comment function. 
Can anyone provide an example of reading a file, carriage returns and all, into a variable or property and adding to the zip file as a comment? 
Can anyone provide an example of using the zip target to add the contents of a file to the zip file as a comment?
 
Thank you,
Chuck Holzwarth

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>
