XSD and WSDL in different directories - maven

Question

At my work used jaxws-maven-plugin for code generation.
I have two projects are "common" and'' client ". Structure roughly as follows:
app/
  common/
   resource/
    some.xsd
  client/
   resource/
    some.wsdl
How can I generate classes from wsdl in the project "client", using the xsd from the project "common"?
pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<verbose>true</verbose>
<bindingFiles>
<bindingFile>${project.parent.basedir}/common/resource/some.xsd</bindingFile>
</bindingFiles>
<wsdlFiles>
<wsdlFile>/resource/some.wsdl</wsdlFile>
</wsdlFiles>
</configuration>
</execution>
</executions>
</plugin>

First of all you should stick to the maven conventions, use src/main/resources/ directories for resources.
After doing that then you can use the maven-dependency-plugin:unpack-dependencies to unpack the common jar file to access the some.xsd:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.stackoverflow.Q13155047</groupId>
<artifactId>app</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>client</artifactId>
<name>${project.artifactId}-${project.version}</name>
<properties>
<schema.location>${project.build.directory}/schemas</schema.location>
</properties>
<dependencies>
<dependency>
<groupId>com.stackoverflow.Q13155047</groupId>
<artifactId>common</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.5.1</version>
<executions>
<execution>
<id>unpack-dependencies</id>
<phase>generate-sources</phase>
<goals>
<goal>unpack-dependencies</goal>
</goals>
<configuration>
<includes>**/*.xsd</includes>
<outputDirectory>${schema.location}</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxws-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>wsimport</goal>
</goals>
<configuration>
<verbose>true</verbose>
<bindingDirectory>${schema.location}</bindingDirectory>
<bindingFiles>
<bindingFile>some.xsd</bindingFile>
</bindingFiles>
<wsdlDirectory>src/main/resources</wsdlDirectory>
<wsdlFiles>
<wsdlFile>some.wsdl</wsdlFile>
</wsdlFiles>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
The jaxws-maven-plugin is bound to the generate-sources phase so adding the maven-dependency-plugin before the jaxws-maven-plugin and to the same phase makes sure that it unpacks everything before applying the wsimport goal.
Make sure that <bindingDirectory/> and <wsdlDirectory/> are correct.
This is how you should do it if you have the *.xsd files in another project. Never access other projects with relative paths. Each project should only access other resources using the dependency mechanism.
