hbm2java 3 - can't find Mapping class

Question

I use the plugin below to generate my Entity classes. When I execute command mvn hibernate3:hbm2java I did get this error:

There was an error creating the AntRun task.: An Ant BuildException has occured: java.lang.NoClassDefFoundError: org/hibernate/engine/Mapping: org.hibernate.engine.Mapping

I did try every hibernate version but I can't find the one that contains indicated class.

Edit: JDK 11 is used.

I just used the new version of the tool and everything works fine

<plugin>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-tools-maven-plugin</artifactId>
    <version>5.4.20.Final</version>
    <configuration>
        <propertyFile>${project.basedir}/src/main/resources/hibernate/hibernate.properties</propertyFile>
        <revengFile>${project.basedir}/src/main/resources/hibernate/hibernate.reveng.xml</revengFile>
        <ejb3>true</ejb3>
        <jdk5>true</jdk5>
        <outputDirectory>${project.basedir}/src/main/java</outputDirectory>
        <packageName>com.cm.sourcegenerator.entity</packageName>
    </configuration>
    <dependencies>
        <!-- DB Driver of your database -->
        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
            <version>${mysql.version}</version>
        </dependency>
    </dependencies>
</plugin>

Answer 2

The Mapping interface was removed in Hibernate 4 and later versions. Instead, you can use the MetadataImplementor interface to access the metadata of your entities.

Since you are using Hibernate 4.3.11. Final, you can try changing your hibernate3-maven-plugin configuration to use the MetadataSources tool instead of HibernateTool. You can do this by replacing your current configuration with:

<metadataSources destdir="${project.build.sourceDirectory}">
    <classpath>
        <path location="${project.build.sourceDirectory}/classes"/>
    </classpath>
    <configuration>
        <jdbc-connection>
            <!-- your database connection details here -->
        </jdbc-connection>
        <hibernate-mapping package="com.cm.sourcegenerator">
            <fileset dir="${basedir}/src/main/resources/hibernate">
                <include name="**/*.hbm.xml"/>
            </fileset>
        </hibernate-mapping>
    </configuration>
</metadataSources>
