How do I retrieve Composer via Ant?

Question

I'm trying to get make my Ant script retrieve Composer for me. Composer is a dependancy manager for PHP. According to the doc one needs to run this command: "curl -s https://getcomposer.org/installer | php" which will download Composer.phar into the directory I'm in. This works as intended when running from a terminal.

How do I setup the Ant build file for this? So far I've got this segment for the "composerget" target, but it's doesn't save the file, only output it in my command shell:

....    
<target name="composerget" description="Composer update dependencies">
    <exec executable="curl"> 
        <arg line="-s" />
            <arg line="https://getcomposer.org/installer"/>
        <arg line="| php" />
    </exec>
  </target>
....

Any help is greatly appeciated.

<target name="composerget" description="Composer update dependencies">
    <exec executable="/bin/bash">
        <arg value="-c" />
        <arg value="curl -s https://getcomposer.org/installer | php" />
    </exec>
</target>

Should do the trick.

The pipe (|) can only be used in a shell script. You're passing it as an argument to curl. So you need to execute a shell script - which you can do with bash -c and passing the command as a shell statement.
