This issue appears to have been reported before:

http://www.mail-archive.com/users@maven.apache.org/msg16864.html

Would seem to be due to incorrect class loader. Any temporary workarounds for this issue will be most gratefully received.

I have the same problem, I tried to redefine the classpath inside ant task, and the same problem appeared.
Does anyone have idea how to correct this? or any workaround?

Thanks in advance,

I found a comment in maven.xml file, it tries to redefine the classpath. See below:

<!-- When invoking ant:ant, ant's task rmic and xslt are broken due to
a null classloader. This will only be fixed in Maven 2.0, so
below is a workaround -->

<goal name="invoke-ant" description="execute ant">
<j:set var="log.name" value="${glassfish.module.name}.log"/>
<ant:delete file="${log.name}" failonerror="false"/>
<j:catch>
<ant:record name="${log.name}" loglevel="verbose" action="start"/>
</j:catch>

<java classname="org.apache.tools.ant.Main" fork="true" failonerror="false" maxmemory="128M">
<classpath>
<fileset dir="${glassfish.home}/lib/ant/lib">
<include name="*.jar" />
</fileset>
<pathelement path="${java.home}/../lib/tools.jar" />
</classpath>
<sysproperty key="ant.home" value="${glassfish.home}/lib/ant" />
<arg line="-f ${module.dir}/build.xml -Dglassfish.home=${glassfish.home} ${ant.target}" />
</java>
</goal>
