generate java classes from xsd importing other xsd from jar provided via catalog

I have some XSD where some share common definitions. I separated this common definitions into a separate XSD. So far I imported this common.xsd via relative paths across the projects. Thsi worked because all projects kived in the dame SCM repository.

Now I separate the projects into separate SCM repositories and I need to change the access to the common.xsd whch already lives in its own project (common-xml.jar).

I read tis: http://www.sagehill.net/docbookxsl/WriteCatalog.html and https://github.com/highsource/maven-jaxb2-plugin/wiki/Using-Catalogs but it does not work or me. The catalog is not used and xjc looks up the common.xsd in the path configuret in maven-jaxb2-plugin/configuration/schemaDirectory.

Even if I add maven-jaxb2-plugin/configuration/arg>-Dxml.catalog.verbosity=999 (or run mvn -X -Dxml.catalog.verbosity=999 ... it does not even tell to read the catalog file.

I only get output for the catalog file when I use the XML form and keep the <!DOCTYPE ..:> element, but this leads to a timeout since the proxy does only allow browsers to connect to the internet (corporate policy).

I also read this answer Maven - Have an XSD as a dependency but it results in the same problem: xjc looks in the schema directory for the file to include but I want to avoid to extract it to a place where it might by checked in into the SCM accidentally...

How do I force xjc to lookup the location for the XSD to import somewere else?

this is my maven project configuration:

 <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.14.0</version> <configuration> <args>-Dxml.catalog.verbosity=999</args> <clearOutputDir>true</clearOutputDir> <removeOldOutput>true</removeOldOutput> <specVersion>2.2</specVersion> <arguments>-Xcommons-lang</arguments> <schemaDirectory>../src/main/xsd</schemaDirectory> <catalogs> <catalog> <dependencyResource> <groupId>my.group.id</groupId> <artifactId>common-xml-definitions</artifactId> <resource>catalog.xml</resource> <!-- alternatively <resource>catalog.cat</resource> for plain text version -->; </dependencyResource> </catalog> </catalogs> <schemaIncludes> <schemaInclude>*.xsd</schemaInclude> </schemaIncludes> <bindingDirectory>../src/main/xjb</bindingDirectory> <bindingIncludes> <bindingInclude>bindings.xml</bindingInclude> </bindingIncludes> <schemaLanguage>XMLSCHEMA</schemaLanguage> <generatePackage>a.package.name</generatePackage> <verbose>false</verbose> <args> <arg>-XtoString</arg> <arg>-Xequals</arg> <arg>-XhashCode</arg> </args> <plugins> <plugin> <groupId>com.buschmais.jaxbfx</groupId> <artifactId>jaxbfx-plugin</artifactId> <version>1.1.0</version> </plugin> <plugin> <groupId>org.jvnet.jaxb2_commons</groupId> <artifactId>jaxb2-basics</artifactId> <version>0.12.0</version> </plugin> </plugins> </configuration> </plugin> 

this is the catalog file:

• xml version:

   <?xml version="1.0"?> <!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd"> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="public"> <rewriteSystem systemIdStartString="http://my.url/commonDefinitions" rewritePrefix="maven:my.package:common-xml-definitions:jar::!/xsd" /> </catalog> 

• plain text version:

  REWRITE_SYSTEM "http://my.url/commonDefinitions" "maven:my.package:common-xml-definitions:jar::!/xsd" 

The beginning ot the tagret XSD is:

<?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:codef="http://my.url/commonDefinitions" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" jxb:version="1.0" elementFormDefault="qualified"> <xs:import namespace="http://my.url/commonDefinitions" schemaLocation="commonDefinitions.xsd" /> <!-- ... --> </xs:schema>
