maven设置打jar包并引入依赖包

--------------------------------------------------------方法一：将jar包和项目打在一起---------------------------------

1.修改pom根节点下packaging属性为jar

2.修改pom根节点下build为:

    <build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>com.hbase2Redis.Hbase2Redis</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

3.使用maven install 打包,将在target下生成项目jar包xxx-with-dependencies.jar复制出来,执行java -jar xxx-with-dependencies.jar即可运行。

--------------------------------------------------------方法二：将jar包和项目分离---------------------------------------

1.修改pom根节点下packaging属性为jar

2.修改pom根节点下build为:

        <finalName>Hbase2Redis</finalName>
        <pluginManagement>
            <plugins>

                </executions>
            </plugin>
        </plugins>
    </build>

3.使用maven install 打包,将在target下生成项目jar包xxx.jar及lib文件夹,将这两者放在同一目录下，执行java -jar xxx.jar即可运行。

将依赖打入jar包，由于maven管理了所有的依赖，所以将项目的代码和依赖打成一个包对它来说是顺理成章的功能。maven的这个功能之前就用过，但这次使用时忘了细节，只记得用maven的assembly插件，但assembly插件功能强大，可以打zip、war各种包，所以一下子找不到如何将依赖打入jar包了。浪费了一点时间，所以一定要记录一下。

在pom.xml中加入如下配置即可，关键是configuration-descriptorRefs-descriptorRef，这个就表示要将依赖打入jar包。

Xml代码  

<plugin>  

  <artifactId>maven-assembly-plugin</artifactId>  

  <configuration>  

    <descriptorRefs>  

      <descriptorRef>jar-with-dependencies</descriptorRef>  

    </descriptorRefs>  

  <archive>  

    <manifest>  

      <mainClass></mainClass>  

    </manifest>  

  </archive>  

  </configuration>  

  <executions>  

    <execution>  

      <id>make-assembly</id>  

      <phase>package</phase>  

      <goals>  

        <goal>single</goal>  

      </goals>  

   </execution>  

  </executions>  

</plugin>
