我们的项目正在从JDK8升级到JDK11。 用Ant生成WSDL时，出现错误。 我已经为此工作了几天，但是没有找到任何解决方案。
<path id="wsgen.main.classpath">
<fileset dir="${dir.externalLib}/jaxws-ri2.3.0/lib">
<include name="**/*.jar" />
</fileset>
</path>
...
<target name="generate_linux_wsdl">
<delete dir="${dir.temp}/WSDL"/>
<mkdir dir="${dir.temp}/WSDL"/>
<java classname="com.sun.tools.ws.WsGen">
<arg value="-d"/>
<arg value="${dir.temp}/WSDL"/>
<arg value="-r"/>
<arg value="${dir.temp}/WSDL"/>
<arg value="-cp"/>
<arg value="${wsgen.linux.classpathforrps}"/>
<arg value="${linux.serviceimpl.class}"/>
<arg value="-wsdl"/>
<arg value="-servicename"/>
<arg value="${linux.service.name}"/>
<classpath refid="wsgen.main.classpath"/>
</java>
</target>
这是ant文件。

我不知道错误在哪里。 我可以确认此ant任务正在jdk8中工作。升级到jdk11后，我包含了jaxws-ri2.3.0
