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>
