开发的java项目需要部署在服务器上，以

nohup java -cp $javaclasspath:${APP}

的方式去启动运行，因而需要将maven管理的依赖拷贝出来，随项目jar一起部署

使用maven-dependency-plugin插件来做拷贝工作，如下所示：

<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>
						<!-- <outputDirectory>${project.build.directory}/lib</outputDirectory> -->
						<overWriteReleases>false</overWriteReleases>
						<overWriteSnapshots>false</overWriteSnapshots>
						<overWriteIfNewer>true</overWriteIfNewer>
					</configuration>
				</execution>
			</executions>
		</plugin>
	</plugins>
</build>

发现项目编译报错，错误内容如下所示：

解决办法：

在<build>节点内，<plugins>节点之前加入

        <pluginManagement>
			<plugins>
				<!-- Ignore/Execute plugin execution -->
				<plugin>
					<groupId>org.eclipse.m2e</groupId>
					<artifactId>lifecycle-mapping</artifactId>
					<version>1.0.0</version>
					<configuration>
						<lifecycleMappingMetadata>
							<pluginExecutions>
								<pluginExecution>
									<pluginExecutionFilter>
										<groupId>org.apache.maven.plugins</groupId>
										<artifactId>maven-dependency-plugin</artifactId>
										<versionRange>[1.0.0,)</versionRange>
										<goals>
											<goal>copy-dependencies</goal>
											<goal>unpack</goal>
										</goals>
									</pluginExecutionFilter>
									<action>
										<ignore />
									</action>
								</pluginExecution>
							</pluginExecutions>
						</lifecycleMappingMetadata>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>

完整的pom配置如下所示：

    <build>
		<pluginManagement>
			<plugins>
				<!-- Ignore/Execute plugin execution -->
				<plugin>
					<groupId>org.eclipse.m2e</groupId>
					<artifactId>lifecycle-mapping</artifactId>
					<version>1.0.0</version>
					<configuration>
						<lifecycleMappingMetadata>
							<pluginExecutions>
								<pluginExecution>
									<pluginExecutionFilter>
										<groupId>org.apache.maven.plugins</groupId>
										<artifactId>maven-dependency-plugin</artifactId>
										<versionRange>[1.0.0,)</versionRange>
										<goals>
											<goal>copy-dependencies</goal>
											<goal>unpack</goal>
										</goals>
									</pluginExecutionFilter>
									<action>
										<ignore />
									</action>
								</pluginExecution>
							</pluginExecutions>
						</lifecycleMappingMetadata>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>
		<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>
							<!-- <outputDirectory>${project.build.directory}/lib</outputDirectory> -->
							<overWriteReleases>false</overWriteReleases>
							<overWriteSnapshots>false</overWriteSnapshots>
							<overWriteIfNewer>true</overWriteIfNewer>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
