Generate Java class based on XSD without block substitution?

问题

I am getting below error while maven build using jaxb(maven-jaxb2-plugin) compiler

A class/interface with the same name "org.somePackage.customer" is already in use.
    Use a class customization to resolve this conflict.

What does not work

 <xsd:element name="customer" >
         ........
 </xsd:element>
 <xsd:element name="permanentCustomer" type="customer"/>

What works

<xsd:element name="customer" block="substitution">
 ........
</xsd:element>
<xsd:element name="permanentCustomer" type="customer"/>

I am not sure why removing block attribute creating issue here ?

My guess is jaxb compiler again trying to create the customer class based on element name="permanentCustomer" which it has already created based on element name ="customer". So I don't want to create java object for permanentCustomer while unmarshalling as it has been already created while customer creation. Is there a way to do that ?
