错误提示：

No enclosing instance of type UpdataInfoParser is accessible. Must qualify the allocation with an enclosing instance of type UpdataInfoParser

 (e.g. x.new A() where x is an instance of UpdataInfoParser).

解决方法：

静态方法只能调用静态内部类。

public  class UpdataInfo前加上static。

public class UpdataInfoParser

{

    public static UpdataInfo getUpdataInfo(InputStream is) throws Exception

   {

        UpdataInfo info = new UpdataInfo();

   }

    public  class UpdataInfo

   {

   }

}
