maven打包的時候不會自動把依賴的專案打成jar放在專案中，如果需把管理的jar放在target/lib目錄下，可以在pom.xml新增：

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>com.myhexin.main.Main</mainClass>
                        </manifest>
                        <manifestEntries>  
						   <Class-Path>.</Class-Path>  
						  </manifestEntries>  
                    </archive>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-dependency-plugin</artifactId>
                <executions>
                    <execution>
                        <id>copy</id>
                        <phase>install</phase>
                        <goals>
                            <goal>copy-dependencies</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>
                                target/lib
                            </outputDirectory>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
