Using a Specific JAXB Version - highsource/jaxb-tools GitHub Wiki

There are differences between JAXB 2.0, 2.1 and 2.2. By default, maven-jaxb2-plugin uses the latest available version of the latest available specification.

Do not forget to use the appropriate version of jaxb-impl.

If you need to stick to a specific version of the JAXB specification, there are two ways to accomplish this.

You can specify the version of the JAXB specification using the following configuration option:

• specVersion - Version of the JAXB specification (ex. 2.0, 2.1 or 2.2).

Alternatively you may also use maven-jaxb20-plugin, maven-jaxb21-plugin or maven-jaxb22-plugin instead of maven-jaxb2-plugin to make your dependency on JAXB specification version more explicit:

<plugin>
	<groupId>org.jvnet.jaxb2.maven2</groupId>
	<artifactId>maven-jaxb20-plugin</artifactId>
	<executions>
		<execution>
			<goals>
				<goal>generate</goal>
			</goals>
		</execution>
	</executions>
</plugin>

All these plugins have identical configuration options (except that specVersion is ignored in maven-jaxb2X-plugins, it only makes sense in maven-jaxb2-plugin).
