How to generate Java classes from WSDL with jaxb2-maven-plugin 2.x?

Question

I am trying using the pluggin jaxb2-maven-plugin to create the Java class from the wsdl.

With the version 1.5 this code from Generate classes with jaxb2-maven-plugin from WSDL works:

        <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxb2-maven-plugin</artifactId>
                <version>1.5</version>
                <executions>
                    <execution>
                        <id>xjc</id>
                        <goals><goal>xjc</goal></goals>
                    </execution>
                </executions>
                <configuration>
                    <!-- Package to store the generated file -->
                    <packageName>com.example.demo.wsdl</packageName>
                    <!-- Treat the input as WSDL -->
                    <wsdl>true</wsdl>
                    <!-- Input is not XML schema -->
                    <xmlschema>false</xmlschema>
                    <!-- The WSDL file that you saved earlier -->
                    <schemaFiles>horarios.wsdl</schemaFiles>
                    <!-- The location of the WSDL file -->
                    <schemaDirectory>${project.basedir}/src/main/resources</schemaDirectory>
                    <!-- The output directory to store the generated Java files -->
                    <outputDirectory>${project.basedir}/src/main/java</outputDirectory>
                    <!-- Don't clear output directory on each run -->
                    <clearOutputDir>false</clearOutputDir>
                </configuration>
            </plugin>

But when use plugin version 2.3.1, I get this error:

Failed to execute goal org.codehaus.mojo:jaxb2-maven-plugin:2.3.1:xjc (xjc) on project demo: MojoExecutionException: NoSchemasException -> [Help 1]

Does someone know how use WSDL file with this new plugin version?

I have already found the solution.

When the jaxb2-maven-plugin version is >= 2.0 you have to use the follow configuration:

             <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxb2-maven-plugin</artifactId>
                <version>2.3.1</version>
                <executions>
                    <execution>
                        <id>xjc</id>
                        <goals>
                            <goal>xjc</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <packageName>com.example.demo.wsdl</packageName>
                    <sourceType>wsdl</sourceType>
                    <sources>
                        <source>src/main/resources/horarios.wsdl</source>
                    </sources>
                    <outputDirectory>target/generated-sources/</outputDirectory>
                    <clearOutputDir>false</clearOutputDir>
                </configuration>
            </plugin>

The difference is not only the syntax. That version does not create the class within the project (src/main/java), it creates in the directory that you wrote in outputDirectory and in the package of packageName.

When you use the class generated it is transparent like if it would be in the same project.

If you want to begin with a XSD:

              <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxb2-maven-plugin</artifactId>
                <version>2.3.1</version>
                <executions>
                    <execution>
                        <id>xjc</id>
                        <goals>
                            <goal>xjc</goal>
                        </goals>
                    </execution>
                </executions>

                <configuration>
                    <xjbSources>
                        <xjbSource>src/main/resources/global.xjb</xjbSource>
                    </xjbSources>
                    <sources>
                        <source>src/main/resources/Ventas.xsd</source>
                    </sources>
                    <outputDirectory>${basedir}/src/main/java</outputDirectory>
                    <clearOutputDir>false</clearOutputDir>
                </configuration>
            </plugin>
