使用 JAXB（或其他）从 maven 中的 XSD maven 依赖项生成 Java 类

Question

I have a data model stored in the Maven repo as an XSD file. My goal is to create a jar with all the Java classes representing this model. I want to use maven and JAXB to do this. I know about the maven-jaxb2-plugin (codehouse-mojo and java-net, not sure yet how they differ) but I don't see a way to use XSD from the maven dependency as an input. Do I have to write my own plugin to do this?

It doesn't have to be JAXB if there is a better tool to it.

Check the documentation , it's right there. See Specifying What To Compile - Specifying URLs, filesets and Maven artifact resources .

Example:

<configuration>                                                                                         
    <schemas>                                                                                       
        <!--
            Compiles a schema which resides
            in another Maven artifact.
        -->
        <schema>                                                                                
            <dependencyResource>                                                            
                <groupId>org.jvnet.jaxb2.maven2</groupId>                               
                <artifactId>maven-jaxb2-plugin-tests-po</artifactId>                    
                <!-- Can be defined in project dependencies or dependency management -->
                <version>${project.version}</version>                                   
                <resource>purchaseorder.xsd</resource>                                  
            </dependencyResource>                                                           
        </schema>                                                                                
    </schemas>                                                                                      
</configuration>

You can also use catalogs to rewrite schema URLs to Maven artifact resources .

Example:

REWRITE_SYSTEM "http://schemas.opengis.net" "maven:org.jvnet.ogc:ogc-schemas:jar::!/ogc"

This will rewrite an URI http://schemas.opengis.net/ows/2.0/owsAll.xsd to maven:org.jvnet.ogc:ogc-schemas:jar::!/ogc/ows/2.0/owsAll.xsd . This will reference the ogc/ows/2.0/owsAll.xsd resource in ogc-schemas JAR artifact.

As far as I know, these features are unique to the maven-jaxb2-plugin .
