schemaDirectory/schemaIncludes don't seem to work as expected

[robertpatrick]

I have an existing Java project that uses JAXB 2.x that I am trying to move to JAXB 3.0 and as such, have modified the project to use the org.jvnet.jaxb:jaxb-maven-plugin:3.0.2 plugin's generate goal.

The schemas are located in subdirectories under src/main/resources. For example:

src/main/resources/com/mycompany/package1/package1.xsd
src/main/resources/com/mycompany/package2/package2.xsd
src/main/resources/com/mycompany/package3/package3.xsd

I have tried all sorts of values for schemaDirectory and schemaIncludes and nothing seems to work since I get this message from running the build:

[INFO] --- jaxb:3.0.2:generate (generate-package1-classes) @ comdev ---
[WARNING] No schemas to compile. Skipping XJC execution. 

My plugin declaration is pretty simple so I do not understand why this isn't working:

            <plugin>
                <groupId>org.jvnet.jaxb</groupId>
                <artifactId>jaxb-maven-plugin</artifactId>
                <version>3.0.2</version>
                <executions>
                    <execution>
                        <id>generate-package1-classes</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                        <configuration>
                            <specVersion>3.0</specVersion>
                            <episodeFile>src/main/resources/jaxb-episode.xsl</episodeFile>
                            <schemaDirectory>src/main/resources/com/mycompany/package1</schemaDirectory>
                            <schemaIncludes>
                                <include>package1.xsd</include>
                            </schemaIncludes>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

If I place all of my schema in src/main/resources directly and remove the schemaDirectory and schemaIncludes, the plugin finds the schemas and is able to compile them.

Same issue with 4.0.8. Can someone please explain how these configuration parameters are supposed to work?

Hi @robertpatrick

I'll try to reproduce your issue and see what could be wrong in your configuration.

Could you provide with a MRE (Minimal Reproductible Exemple) please ? I didn't manage to get the same problem as yours 😞
