hibernate - error when including dependency within the plugin under execution in maven -

i have following pom.xml works if execute mvn goal mvn hibernate3:hbm2java directly. want make part of execution during generate-entity phase. have few dependencies included in plugin.

here working pom.

   <plugins>          <plugin>            <groupid>org.codehaus.mojo</groupid>            <artifactid>hibernate3-maven-plugin</artifactid>            <version>2.2</version>              <configuration>                <components>                  <component>                    <name>hbm2java</name>                    <implementation>jdbcconfiguration</implementation>                    <outputdirectory>src/main/java</outputdirectory>                  </component>                </components>                <componentproperties>                  <revengfile>src/main/resources/reveng.xml</revengfile>                  <propertyfile>src/main/resources/hibernate.properties</propertyfile>                  <packagename>com.whatever.domain</packagename>                  <jdk7>true</jdk7>                  <ejb3>true</ejb3>                </componentproperties>              </configuration>              <dependencies>                <dependency>                  <groupid>cglib</groupid>                  <artifactid>cglib-nodep</artifactid>                  <version>2.2.2</version>                </dependency>                <dependency>             <groupid>mysql</groupid>             <artifactid>mysql-connector-java</artifactid>             <version>5.1.22</version>         </dependency>              </dependencies>            </plugin>         </plugins> 

this works expected when execute mvn hibernate3:hbm2java.

but included execution section in pom.xml. eclipse prompts me error message

cvc-complex-type.2.4.a: invalid content found starting element 'dependencies'. 1 of '{"http:// maven.apache.org/pom/4.0.0":inherited}' expected.

here modified pom.xml has issues near dependencies block inside plugin

as mentions @ "guide configuring plug-ins: using dependencies tag", dependencies tags available @ plugin level, not @ execution level following example: -

<build>     <plugins>         <plugin>             <groupid>some-group</groupid>             <artifactid>some-artifact</artifactid>             <version>some-version</version>             ...             <dependencies>                 <dependency>                     <groupid>some-dependency-group</groupid>                     <artifactid>some-dependency-artifact</artifactid>                     <version>some-dependency-version</version>                 </dependency>             </dependencies>         </plugin>     </plugins> </build>
