从xsd生成Java类，从通过目录提供的jar导入其他xsd

Question

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:

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>

the maven error message for the XML-Catalog with DOCTYPE is:

Answer 1

sometimes reading carefully solves problems...

https://github.com/highsource/maven-jaxb2-plugin/wiki/Using-Catalogs :

Due to the bug in the XJC this only works if schemaLocation is not specified . So, unfortunately the following combination does not work at the moment.

PUBLIC "http://www.w3.org/1999/xlink" "w3c/1999/xlink.xsd"
<import namespace="http://www.w3.org/1999/xlink" schemaLocation="http://www.w3.org/1999/xlink.xsd" />
