maven - Maven/Ant: Move a directory out of another directory of unknown name

Question

In a Maven project, I have a zip containing a directory, which I need the content from. I.e.

foo.zip
    somedir
         content

I don't know the name of somedir. But there's just this one dir.

How can I get content into some specific dir? (target)

If you're using Ant 1.8.2 or newer, a <cutdirsmapper> strips a configured number of leading directories from each source file name:

<project name="ant-unzip-mapped-dir" default="run" basedir=".">
    <target name="run">
        <unzip src="foo.zip" dest="target">
            <cutdirsmapper dirs="1"/>
        </unzip>
    </target>
</project>

somedir/content becomes content in your example.
