maven-jaxb2-plugin episodes in same pom - maven

Question

I have been looking around a lot regarding this issue. I found some suggestions, but I cannot make them work, so maybe I'm doing something wrong.
Problem
I have inter-depending XSDs in the same maven project. I have commonA.xsd & commonB.xsd which have generic types and I have a specific.xsd which references those two. The problem is that I cannot make the hierarchical generation work.
My current pom.xml
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.12.3</version>
<executions>
<execution>
<id>base</id>
<phase>generate-sources</phase>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<schemaIncludes>
<include>commonA.xsd</include>
<include>commonB.xsd</include>
</schemaIncludes>
<generatePackage>common</generatePackage>
<generateDirectory>${project.build.directory}/generated-sources/xjc-common</generateDirectory>
</configuration>
</execution>
<execution>
<id>specific</id>
<phase>generate-sources</phase>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<schemaIncludes>
<include>specific.xsd</include>
</schemaIncludes>
<generatePackage>specific</generatePackage>
<generateDirectory>${project.build.directory}/generated-sources/xjc-specific</generateDirectory>
</configuration>
</execution>
</executions>
</plugin>
Attempted solutions
Referencing the episode file
I found this page https://stackoverflow.com/a/11135186/284263 where it is proposed to reference the episode file.
[ERROR] Error while parsing schema(s).Location [ file:/path/to/xsd/COMMONA.XSD{122,60}].com.sun.istack.SAXParseException2; systemId: file:/path/to/xsd/COMMONA.XSD; lineNumber: 122; columnNumber: 60; (the above customization is attached to the following location in the schema)
This didn't work for me and it also feels a bit hacky.
Create a bindings.xjb
I also looked into this answer https://stackoverflow.com/a/22559100/284263. I cannot find any 'real' examples anywhere, and I don't know if this is the correct approach anyway for my case.
Referring to maven artifact
I found in the plugin's documentation that I can do something like this:
<episodes>
<episode>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin-tests-po</artifactId>
<!-- Version of the artifact. May be omitted.
The plugin will then try to find the version using
the dependencyManagement and dependencies of the project. -->
<version>${project.version}</version>
</episode>
</episodes>
This is an external reference, as far as I understand. It doesn't work, because the artifact doesn't exist in the repo yet, e.g. when developing and having a SNAPSHOT version, or might be risky because it will refer an older version.
Any suggestions or corrections?
Thanks for your time.
