错误maven中的“复制依赖”

我想在安装项目时将maven中的lib依赖项复制到lib目录中。我在我的pom文件中使用过。错误maven中的“复制依赖”

<project> 
    <dependencies> 
     ... 
    </dependencies> 

    <build> 
     <plugins> 
      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-dependency-plugin</artifactId> 
       <version>2.4</version> 
       <executions> 
        <execution> 
         <id>copy-dependencies</id> 
         <phase>package</phase> 
         <goals> 
          <goal>copy-dependencies</goal> 
         </goals> 
         <configuration> 
          <outputDirectory>${project.build.directory}/dependencies</outputDirectory> 
         </configuration>  
        </execution> 
       </executions> 
      </plugin> 
     </plugins> 
    </build> 
</project>

但它下面的错误：

Description Resource Path Location Type 
maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e. pom.xml /jasperreports-test line 60 Maven Project Build Lifecycle Mapping Problem

我试图修复它。这是我项目中的pom文件。

<project> 

    <groupId>com.vccorp.adtech</groupId> 
    <artifactId>UserAgentService</artifactId> 
    <version>14.06.201</version>

             <artifactId>maven-dependency-plugin</artifactId> 
             <versionRange>[1.0.0,)</versionRange> 
             <goals> 
              <goal>copy-dependencies</goal> 
             </goals> 
            </pluginExecutionFilter> 
            <action> 
             <ignore /> 
            </action> 
           </pluginExecution> 
          </pluginExecutions> 
         </lifecycleMappingMetadata> 
        </configuration> 
       </plugin> 
      </plugins> 
     </pluginManagement> 
     <plugins>

          <goal>copy-dependencies</goal> 
         </goals> 
         <configuration> 
          <outputDirectory> 
           ${project.build.directory}/lib 
          </outputDirectory> 
         </configuration> 
        </execution> 
       </executions> 
      </plugin> 
     </plugins> 
    </build> 
</project>

但是，当安装错误如下：

你为什么要复制依赖关系？如果你只是想制作一个可执行的jar文件，可以看看maven-assembly插件。 –

感谢让雷米。我使用maven-assembly插件，但有时我想使用复制依赖关系的原因。 – tienthanhakay

我自己用它来达到这个目的。没关系，在这一刻，我没有任何线索（没有深入自己研究）来解决你的问题。 –
