The problem can be it scans for wrong .xjb file which is designed for another shema.

Plugin scans all .xjb files by default. I had to put this one for plugin org.jvnet.jaxb:jaxb-maven-plugin:4.0.9:

<configuration>
...
    <bindingIncludes>
        <!-- DO NOT REMOVE: we skip all *.xjb -->
    </bindingIncludes>
