Generate JAX-WS classes from WSDL file using Maven plugin with Java11

Question

In Java 11, JAX-WS has been removed from the JDK. It prevents to generate easily JAX-WS classes with a Maven plugin using wsimport under the hood. I am using the following configuration for the Maven plugin org.codehaus.mojo:jaxws-maven-plugin.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>wsimport</goal>
            </goals>
            <configuration>
                <extension>true</extension>
                <packageName>tech.myproject.service</packageName>
                <wsdlFiles>
                    <wsdlFile>${basedir}/src/main/resources/wsdl/service.wsdl</wsdlFile>
                </wsdlFiles>
                <wsdlLocation>/wsdl/service.wsdl</wsdlLocation>
            </configuration>
        </execution>
    </executions>
</plugin>

Is there an easy way to install wsimport or to use another plugin bundling an architecture specific wsimport to continue generating WSDL classes?

Solution 1

the new version of jaxws-maven-plugin (link) can generate Java classes with Java 11, using the plugin as follows:

<build>
<plugins>
...
<plugin>
    <groupId>com.sun.xml.ws</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.3.2</version>
    <executions>
      <execution>
        <id>generate-java-sources</id>
        <phase>process-sources</phase>
        <goals>
          <goal>wsimport</goal>
        </goals>
        <configuration>
          <extension>true</extension>
          <wsdlFiles>
            <wsdlFile>${project.build.directory}/generated/wsdl/MyService.wsdl</wsdlFile>
          </wsdlFiles>
          <wsdlLocation>/wsdl/MyService.wsdl</wsdlLocation>
        </configuration>
      </execution>
    </executions>
    <dependencies>
      <dependency>
        <groupId>javax.annotation</groupId>
        <artifactId>javax.annotation-api</artifactId>
        <version>1.3.2</version>
      </dependency>
      <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.1</version>
      </dependency>
      <dependency>
        <groupId>javax.xml.ws</groupId>
        <artifactId>jaxws-api</artifactId>
        <version>2.3.1</version>
      </dependency>
      <dependency>
        <groupId>javax.jws</groupId>
        <artifactId>javax.jws-api</artifactId>
        <version>1.1</version>
      </dependency>
    </dependencies>
  </plugin>
</plugins>
</build>

An alternative plugin can also be the cxf-codegen-plugin from Apache CXF (link)

UPDATE

If you want to use the newer JakartaEE 9.0+ packages, you need to use the following plugin, keeping the same configurations:

<build>
<plugins>
...
<plugin>
    <groupId>com.sun.xml.ws</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>3.0.0</version>
    <executions>
      <execution>
        <id>generate-java-sources</id>
        <phase>process-sources</phase>
        <goals>
          <goal>wsimport</goal>
        </goals>
        <configuration>
          <extension>true</extension>
          <wsdlFiles>
            <wsdlFile>${project.build.directory}/generated/wsdl/MyService.wsdl</wsdlFile>
          </wsdlFiles>
          <wsdlLocation>/wsdl/MyService.wsdl</wsdlLocation>
        </configuration>
      </execution>
    </executions>
    <dependencies>
      <dependency>
        <groupId>jakarta.xml.bind</groupId>
        <artifactId>jakarta.xml.bind-api</artifactId>
        <version>3.0.0</version>
        <exclusions>
            <exclusion>
                <groupId>javax.transaction</groupId>
                <artifactId>javax.transaction-api</artifactId>
            </exclusion>
        </exclusions>
      </dependency>
      <dependency>
        <groupId>jakarta.xml.ws</groupId>
        <artifactId>jakarta.xml.ws-api</artifactId>
        <version>3.0.0</version>
      </dependency>
    </dependencies>
  </plugin>
</plugins>
</build>

and for jaxb:

<groupId>com.evolvedbinary.maven.mojohaus</groupId>
<artifactId>jaxb-maven-plugin</artifactId>
<version>3.0.0</version>

Solution 2

Found this - https://github.com/mojohaus/jaxws-maven-plugin/issues/54#issuecomment-440597801 I used the same configuration as for org.jvnet.jax-ws-commons jaxws-maven-plugin. Think it is the same as org.codehaus.mojo, but don't 100% sure.

Tested with JDK 11. All XSD elements, ports and services are generated. You also need to add a few dependencies to your pom. Minimum:

        <dependency>
            <groupId>javax.annotation</groupId>
            <artifactId>javax.annotation-api</artifactId>
            <version>1.3.2</version>
        </dependency>
        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.1</version>
        </dependency>
        <dependency>
            <groupId>javax.xml.ws</groupId>
            <artifactId>jaxws-api</artifactId>
            <version>2.3.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.main.javaee-api</groupId>
            <artifactId>javax.jws</artifactId>
            <version>3.1.2.2</version>
        </dependency>

[Nicolas Henneaux]

Phase <phase>process-classes</phase>was breaking my build since the generated classes were not generated otherwise it's fine, thanks!

[Max Lich]

it does not generate classes with the suffix "Service" for me

[DecKno]

This helped. had to update from <groupId>org.codehaus.mojo</groupId> --> to <groupId>com.sun.xml.ws</groupId> <artifactId>jaxws-maven-plugin</artifactId>. After that had to import few jakarta related dependencies.

[Stéphane Millien]

Be careful the block <configuration> must be outside of block <execution>, it must be at the same level of <plugin>
