How to dump a Mysql database with ANT?

Hello!

I would like to know if possible and how to dump a database through ANT.

I seems to be able to import a dump with ANT with a build.xml like:
    <target description="Creates the database" name="create">
        <sql classpath="mysql-connector-java-3.0.15-ga-bin.jar"
            driver="com.mysql.jdbc.Driver"
            src="create.sql"
            url="jdbc:mysql://localhost:3306/?autoReconnect=true"
            userid="root"
            password="password"/>
    </target>

Best regards
Fredrik
