构建jar后的java CannotResolveClassException

Question

我对这个异常有一个问题，但是当jar id生成时它就会出现

com.thoughtworks.xstream.mapper.CannotResolveClassException: br.com.maquinas.message.SolicitacaoEmail

我的xml：

<solicitacao>
   <to>juliocesar@maquinas.com.br</to>
   <from>impressora@maquinas.com.br</from>
   <text>Envio de relatorio</text>
   <relatorio>blank_a42</relatorio>
   <titulo>rrrr</titulo>
   <formato>xls</formato>
   <parametros>
     <entry>
       <string>statusprop</string>
       <java.util.Arrays_-ArrayList>
         <a class="string-array">
           <string>000</string>
         </a>
       </java.util.Arrays_-ArrayList>
     </entry>
     <entry>
       <string>titulo</string>
       <string>rrrr</string>
     </entry>
   </parametros>
 </solicitacao>

我的代码：

XStream xstream = new XStream();
xstream.alias("solicitacao", br.com.maquinas.message.SolicitacaoEmail.class);
SolicitacaoEmail solicitacao = (SolicitacaoEmail)xstream.fromXML(envio);

事态发展没有显示出任何例外
