maven拷贝外部依赖到指定目录

方法一：使用maven-dependency-plugin插件

<build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-dependency-plugin</artifactId>
                    <executions>
                        <execution>
                            <id>copy-dependencies</id>
                            <phase>package</phase>
                            <goals>
                                <goal>copy-dependencies</goal>
                            </goals>
                            <configuration>
                                <!-- 将工程依赖的jar包，复制至target/lib目录下进行管理，方便已生成jar的工程进行引用。 -->
                                <outputDirectory>${project.build.directory}/lib</outputDirectory>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>
