找不到元素soapenv：Envelope的声明

Question

我正在尝试使用Talend通用模式创建器（基于Java的工具）使用以下XML文件来创建模式。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sys="http://name/WebServices/KP/Tester/SystemOperations.xsd">
   <soapenv:Header/>
   <soapenv:Body>
      <sys:userId></sys:userId>
      <sys:password></sys:password>
      <sys:idleTime></sys:idleTime>
   </soapenv:Body>
</soapenv:Envelope>

但是我遇到了以下错误。

Can not import schema from invalid xml
  org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException: index=0, size=0
      at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:346)
     ...
