将所有库罐放在单独的文件夹中

我有一个Maven Eclipse Java项目。我想请maven将所有必需的库复制到 aaa 文件夹durin Eclipse->Run->Run as->Maveven build-> package 过程我已经为此配置了插件:

                 <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-dependency-plugin</artifactId>
                    <executions>
                        <execution>
                            <id>copy-dependencies</id>
                            <phase>prepare-package</phase>
                            <goals>
                                <goal>copy-dependencies</goal>
                            </goals>
                            <configuration>
                                <outputDirectory>${project.build.directory}/aaa</outputDirectory>
                                <overWriteReleases>false</overWriteReleases>
                                <overWriteSnapshots>false</overWriteSnapshots>
                                <overWriteIfNewer>true</overWriteIfNewer>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>

但看起来添加这个插件在打包过程中不需要任何操作,也不会创建任何文件夹和文件。如何解决这个问题?
