Today I wanted to perform this task, and I run across some issues in the way. So I present here my problem and the solution I found. Perhaps somebody knows a simpler solution!

The problem was this: I was trying to build a distribution package of a Java project which is built with Maven2. In a previous step, several zip files all containing a file named manifest.xml in the root were generated, and I wanted to modify this XML file in all this ZIP files. This is a scheme:

package-file-1.zip
|- contents(DIR)
\- manifest.xml

package-file-2.zip
|- contents(DIR)
\- manifest.xml

    This example modifies the zip files in ${zip.sourcedir} replacing the string & with & in the file manifest.xml of all this zip files and places the modified zip files in the directory target.

    For that, it uses the maven-antrun-plugin including the for and var tasks from the antcontrib tasks(http://ant-contrib.sourceforge.net). This permits to unzip the contents of every zip file into a separate directory. Note also the use of the task basename to extract the name of the zip files out of their path.

                    <unzip src="@{filepath}" dest="target/repair-temp/${for.filename}" encoding="UTF8" />

    In order to write this solution, I got the needed knowledge from this URLs:

    After posting the question, I was able to find a couple of questions related, that could help if one is having problems implementing a similar thing:
