Maven dependency management

Maven dependency management Scenario: jar file from repository not in the format you want.

<dependency>
   <groupid>com.mycompany.feature</groupid>
   <artifactid>entity</artifactid>
   <version>${mycompany-feature-entity-version}</version>
</dependency>

jar file from repository is entity-0.1.0-20130924.075312-18.jar What is needed is entity.jar because jar is referred in persistence.xml Solution: Use maven dependency plugin to configure

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-dependency-plugin</artifactId>
   <version>2.8</version>
   <executions>
      <execution>
         <id>mycopy</id>
         <phase>prepare-package</phase>
         <goals>
            <goal>copy</goal>
         </goals>    
         <configuration>
            <artifactItems>
               <artifactItem>
                  <groupId>com.mycompany.feature</groupId>
                  <artifactId>entity</artifactId>
                  <version>${mycompany-feature-entity-version}</version>
                  <type>jar</type>
                  <overWrite>true</overWrite>
                  <outputDirectory>${project.build.directory}/${project.artifactId}/WEB-INF/lib</outputDirectory>
                  <destFileName>entity.jar</destFileName>
               </artifactItem>
            </artifactItems>
         </configuration>
      </execution>
   </executions>
</plugin>
