maven-jaxb2-plugin ignoring configuration

I'm using maven 3.3.9 and the maven-jaxb2-plugin 0.13.1. But when I try to generate the Java classes, the plugin is not finding my XSD-file.

My pom looks like this:

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.jvnet.jaxb2.maven2</groupId>
                <artifactId>maven-jaxb2-plugin</artifactId>
                <version>0.13.1</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                        <configuration>
                            <schemaDirectory>src/main/resources/schemas</schemaDirectory>                                
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

Everytime I'm executing the goal, I get this message:

[WARNING] No schemas to compile. Skipping XJC execution.

The directory exists under the resources folder, and the XSD is placed there. I have no other pom-files in play.

Any help would be very much appreciated

In case anyone else will hit this. I had a similar issue: the configuration was not picked up by the plugin. I made it work by moving configuration section under plugin declaration instead of execution.

Here's how the working configuration looked like for me (I removed the upper-level elements since they do not matter):

<plugin>
  <groupId>org.jvnet.jaxb2.maven2</groupId>
  <artifactId>maven-jaxb2-plugin</artifactId>
  <version>0.15.1</version>
  <configuration>                          
    <schemaDirectory>src/main/resources/custom-schemas</schemaDirectory>                                
  </configuration>
  <executions>
    <execution>
      <id>generate</id>
      <goals>
        <goal>generate</goal>
      </goals>
    </execution>
  /executions>
</plugin>

Author of maven-jaxb2-plugin here.

Somehow I have a feeling that you're omitting important details. This does not not add up. This is a very basic configuration setting, I'm curious how it can't work.

You only post the pluginManagement part of your pom.xml. If you have just this, it should not work at all as it is just and only a declaration of configuration, not actual usage of the plugin. You need plugins/plugin to actually apply the plugin:

<project ...>
    ...
    <build>
        <plugins>
            ...
            <plugin>
                <groupId>org.jvnet.jaxb2.maven2</groupId>
                <artifactId>maven-jaxb2-plugin</artifactId>
                <version>...</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            ...
        </plugins>
    </build>
    ...
</project>

To analyze the problem, run mvn -X clean generate-sources or mvn -X clean install and check the applied configuration (it will be logged). Post the log here.

If this does not help, send me a PR of a minimal reproducing project under https://github.com/highsource/maven-jaxb2-plugin-support/s/schemaDirectory, I'll take a look.
