The jdtaus-resource-mojo:java-resources goal of the Resource Plugin is bound to the process-resources phase in the build lifecycle. The mojo needs to be setup manually in a project to get executed. To generate an accessor class for a ResourceBundle which is backed by properties file resources of your project add the following to the project's pom.xml.
...
<build>
<plugins>
...
<plugin>
<groupId>org.jdtaus.mojo</groupId>
<artifactId>jdtaus-resource-mojo</artifactId>
<version>${jdtaus-resource-mojo.artifact.version}</version>
<executions>
<execution>
<id>jdtaus-generate</id>
<goals>
<goal>java-resources</goal>
</goals>
</execution>
</executions>
</plugin>
...
<plugins>
</build>
...and add a module descriptor to the project (searched for at src/main/resources/META-INF/jdtaus/module.xml by default) like so
<?xml version="1.0" encoding="UTF-8"?>
<container:module xmlns:container="http://jdtaus.org/core/model/container"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://jdtaus.org/core/model/container http://xml.jdtaus.org/1.0.x/jdtaus-core/jdtaus-core-schemas/jdtaus-container-1.1.xsd">
<container:implementations>
<container:implementation container:identifier="com.yourcompany.YourClass"
container:name="jDTAUS Core ⁑ Resource Mojo"
container:vendor="jDTAUS"

<container:messages>

</container:messages>
</container:implementation>
</container:implementations>
<container:messages>
<container:message container:name="yourMessage">
<container:template container:defaultLanguage="en">
<container:text container:language="en"><![CDATA[English message text with {0} argument]]></container:text>
<container:text container:language="de"><![CDATA[Deutscher Meldungs-Text mit Argument {0}]]></container:text>
</container:template>
<container:arguments>
<container:argument container:index="0" container:name="argumentName" container:type="text"/>
</container:arguments>
</container:message>
</container:messages>
...
</container:module>The goal processes the specified messages and generates accessor classes together with corresponding properties files for all messages from the module descriptor.
