Getting error: The parameters 'includes' for goal org.codehaus.mojo:jaxb2-maven-plugin:1.5:schemagen are missing or invalid - jaxb2-maven-plugin

Question

Below is how I have included org.codehaus.mojo:jaxb2-maven-plugin:1.5 schemagen plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.5</version>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>schemagen</goal>
</goals>
</execution>
</executions>
<configuration>
<includes>
<include>com/abc/domain/**/*.java</include>
</includes>
<outputDirectory>${project.build.directory}/schemas</outputDirectory>
<excludes>
<exclude>**/aspect/*.java</exclude> </excludes>
<verbose>true</verbose>
</configuration>
</plugin>
I am getting this exception:
