无法使用codehaus.mojo jaxb2-maven-plugin创建Java类

Question

I have a spring based web application in which I am trying to consume a SOAP service. I am using jaxb2-maven-plugin(org.codehaus.mojo) for that. However I see an empty jaxb2 folder which is crated under target and I dont see any java classes in it. I have the wsdl placed correctly under the resources folder itself.

Below is the plugin config created in pom.xml

    <build>
        <finalName>${project.artifactId}</finalName>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
            <resource>
                <directory>src/main/java/com/xyz/rap/service/impl/wsdl</directory>
                <targetPath>wsdl</targetPath>
            </resource>
            <resource>
                <directory>src/main/config</directory>
                <targetPath>config</targetPath>
            </resource>
        </resources>

                    <!-- Don't clear output directory on each run -->
                    <clearOutputDir>false</clearOutputDir>
                </configuration>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

Below is the log when I run "maven install"

It says Parsing and compiling the schema in logs but I dont see any java classes getting created in the logs and I see an empty jaxb2 folder and an other empty generated-sources folder getting created. Please refer below image for that:

Answer 1

jaxb2-maven-plugin will create classes by default into target/generated-sources/jaxb . if you are stil not getting classes into target folder then If you are using Eclipse, you can add this folder into your project build path: right-clicking on project and selecting "Build Path > Use Source Folder.

then you need to run mvn clean install it will clean or delete the target folder and regenerate everything.

Answer 2

Try the version 2.2 of the codehaus. Keep in mind that you will need to change your xml a bit since there is a difference between 1.x and 2.x.

Having said that I would like to tell you that I'm having a similar issue. But it could be caused by something else. I'm using IntelliJ and it's generating empty jaxb folder under the /target/generated-sources/.
