Description

org.jvnet.jaxb2.maven2:maven-jaxb2-plugin is a plugin used to generate Java code. It is notably generating a bunch of javax.xml.* code.

To generate code with jakarta namespace, we currently need to migrate to another plugin
com.helger.maven:jaxb40-maven-plugin because the original one seems to no more be active enough, the PR to migrate is still pending.

In case org.jvnet.jaxb2_commons:jaxb2-namespace-prefix is used in combination of it, this one needs to be updated to version 2.0

I think it can be a nice addition to JakartaEE9 recipe.

Example of a typical use case:

<plugin>
                    <groupId>org.jvnet.jaxb2.maven2</groupId>
                    <artifactId>maven-jaxb2-plugin</artifactId>
                    <version>0.15.2</version>
                     <dependencies>
                         <dependency>
                             <groupId>org.jvnet.jaxb2_commons</groupId>
                             <artifactId>jaxb2-namespace-prefix</artifactId>
                            <version>1.3</version>
                         </dependency>
                     </dependencies>
</plugin>
<plugin>
                    <groupId>com.helger.maven</groupId>
                    <artifactId>jaxb40-maven-plugin</artifactId>
                    <version>0.16.1</version>
                     <dependencies>
                         <dependency>
                             <groupId>org.jvnet.jaxb2_commons</groupId>
                             <artifactId>jaxb2-namespace-prefix</artifactId>
                            <version>2.0</version>
                         </dependency>
                     </dependencies>
</plugin>
