[FIXED] How to specify input classes for jaxb2 in pom.xml?

Issue

I am using the schemagen goal of jaxb2-maven-plugin to convert Java classes to xsd. The classes in com.example.entities & com.example.model should be converted & the rest of the packages ignored. How to do this in pom.xml

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

Solution

After wading through really odd FileNotFoundException and ClassNotFoundException, I discovered through this StackOverflow answer, that the jaxb2-maven-plugin has issues with Java 11.

Now, I am using jax-maven-plugin instead, which has simple configuration to include particular folders/packages.

In order to include classes org.examples.models & org.examples.entities only, to be converted to xml:

<plugin>
    <groupId>com.github.davidmoten</groupId>
    <artifactId>jax-maven-plugin</artifactId>
    <version>0.2</version>
    <executions>
        <execution>
            <id>schemagen-source-option</id>
            <phase>generate-sources</phase>
            <goals><goal>schemagen</goal></goals>
            <configuration>
                <classpathScope>compile</classpathScope>
                <sources>
                    <source>${basedir}/src/main/java/org/examples/models</source>
                    <source>${basedir}/src/main/java/org/examples/entities</source>
                </sources>
                <arguments>
                    <argument>-d</argument>
                    <argument>${jaxb.generated}</argument>
                </arguments>
            </configuration>
        </execution>
    </executions>
</plugin>
