JUnitLogPublisherTask

I saw this example that demontrates how to use JUnitLogPublisherTask with one test file.

<junit>
<formatter type="xml" />
<test name="hello.test.HelloTest" outfile="HelloTest"/>
<classpath>
<pathelement path="${basedir}/hello.jar" />
<pathelement path="${junitJar}" />
</classpath>
</junit>

<junitLogPublisher filePath="HelloTest.xml"
buildResultUUID="${buildResultUUID}"
repositoryAddress="${repositoryAddress}"
userId="${userId}"
password="${password}" />

I don't know how I can use this task with many test files. Because I have to use <batchtest> tag when I have many test files. And there is not the attribute "outfile" for this tag.

For example, I have this code in a build.xml:

<junit fork="yes" printsummary="yes" >
<formatter type="xml"/>
<classpath refid="test-classpath"/>
<batchtest fork="yes" todir="${report.dir}">
<fileset dir="${source.test.dir}">
<include name="**/*Test.java"/>
</fileset>
</batchtest>
</junit>

How can I use JUnitLogPublisherTask with this code to publish the test results ?
