Try this approach:

        <configuration>
          <fork>true</fork>
          <maxmem>1024m</maxmem>
          <showDeprecation>true</showDeprecation>
          <showWarnings>true</showWarnings>
          ....etc...
        </configuration>

To know element names to use, use the Name found in the Optional Parameters
section of this page:
