WsGenTask doesn't support the "wsdl" attribute头疼死了，高分求助！

用xfire开发的webServices但是用ant生成代码的时候报这个
Buildfile: D:\mySSHTest\webServicesClient\build.xml
my-test:BUILD FAILED
D:\mySSHTest\webServicesClient\build.xml:14: WsGenTask doesn't support the "wsdl" attributeTotal time: 828 milliseconds
ant文件<?xml version="1.0" encoding="UTF-8"?>

<WsGenTask outputDirectory="${src.dir}" wsdl="${wsdl.path}" package="${code.package}" overwrite="true" />

</project>properties文件为：
src.dir=${basedir}/src
lib.dir=D:/mySSHTest/webservicesAntLib
code.package=com.mz.webservice
wsdl.path=http://localhost:8080/webservicesTest/services/webServicesTest?wsdl启动ant build就报错，而且WsGenTask 我也点不出wsdl，但是为什么别人的就可以呢？？？？？？？？
