maven jaxb2 plugin - JAXB separate episodes with annox customizations fails : SAXParseException2

Question

I have 2 maven modules.

• First one contains only a xsd schema to generate base POJO classes.
• Second on contains a xsd schema that imports first one with a catalog file and generate new POJO classes. Both generation works.

Now, I add annotations to both xsd files with annox (Swagger annotations). First module compilation succeeded but seconds module compilation fails with and exceptions :

[ERROR] Error while generating code.Location : com.sun.istack.SAXParseException2; systemId: jar:file:/C:/commons-0.0.1-SNAPSHOT.jar!/Commons.xsd; lineNumber: 15; columnNumber: 36; compiler was unable to honor annox:annotate schemaBinding customization. It is attached to a wrong place, or its inconsistent with other bindings.

It's been days I'm trying to solve, without success, this error.

Answer 1

There is a bug using annox and episodes.

I've solved the same issue through external binding (xjb file). In this way the schema is also clean.

e.g.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<jaxb:bindings
  xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema"
  xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:annox="http://annox.dev.java.net"
  xsi:schemaLocation="http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
  jaxb:extensionBindingPrefixes="xjc annox"
  version="2.1">

  <jaxb:globalBindings>
    <jaxb:serializable uid="12345"/> 
  </jaxb:globalBindings>


  <jaxb:bindings schemaLocation="domain1.xsd" node="/xs:schema">
    <jaxb:bindings node="xs:complexType[@name='SomeRootType']">
      <annox:annotate>
        <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="SomeRootType"/>
      </annox:annotate>
    </jaxb:bindings>
  </jaxb:bindings>

</jaxb:bindings>
