maven: How to add resources which are generated after compilation phase

Question

I have a maven project which uses wsgen to generate XSD files from the compiled java classes.

The problem is that I want to add the generated files to the jar as resources. But since the resource phase runs before the process-classes phase, I can't add them.

Is there a way to tell maven to add additional resources that were generated at the process-classes phase?

Answer 1

I would suggest to define the output directory for the XSD files into target/classes (may be with a supplemental sub folder which will be packaged later during the package phase into the jar. This can be achieved by using the maven-resources-plugin.

<project>   ...   <build>     <plugins>       <plugin>         <artifactId>maven-resources-plugin</artifactId>         <version>3.0.2</version>         <executions>           <execution>             <id>copy-resources</id>             <phase>process-classes</phase>             <goals>               <goal>copy-resources</goal>             </goals>             <configuration>               <outputDirectory>${project.build.outputDirectory}</outputDirectory>               <resources>                           <resource>                   <directory>${basedir}/target/xsd-out</directory>                   <filtering>false</filtering>                 </resource>               </resources>                           </configuration>                       </execution>         </executions>       </plugin>     </plugins>     ...   </build>   ... </project> 

You need to take care that the resources plugin is positioned after the plugin which is used to call the wsgen part. You can also use the prepare-package phase instead to make sure the resources will be correctly packaged.
