Does this help? I don't quite get what your asking, but here's how I do some related stuff. Bear in mind I'm a Perforce newbie, and I haven't tested this yet. This uses ANT 1.5.3:

<target name="get.buildnum"> <echo message="Getting build.number" /> <available file="${project.dir}\build.number" property="build.number.found" /> <fail unless="build.number.found" message="${project.dir}\build.number not found" /> <property file="${project.dir}\build.number" /> <echo message="... build number found [${cmbuild.number}]" /> </target>

<target name="update.buildnum"> <p4change description="updating build.number from ${cmbuild.number}"/> <p4edit view="//depot/${project.name}/build.number" /> <propertyfile file="${project.dir}/build.number" > <entry key="cmbuild.number" operation="+" value="1" type="int" /> </propertyfile> <p4submit change="${p4.change}" /> </target>

<target name="label" > <p4label view="//depot/${project.name}/..." name="${project.name}.${p4.buildnum}" description="cmbuild"/> <exec failonerror="false" executable="cmd.exe"> <arg value="/c" /> <arg value="p4" /> <arg value="labelsync" /> <arg value="-l" /> <arg value="${project.name}.${p4.buildnum}" /> <arg value="//depot/${project.name}/...#have" /> </exec> </target>

If you need to get a label name into a file you could do:

<echo file="label.property" message="label=${labelname}" /> or in my case it'd be <echo file="label.property" message="label=${project.name}.${p4.buildnum}" />

Sorry if I missed your point, which I suspect I have...
