maven可执行jar包

1. 插件1：

   <build>
   <plugins>
       <!-- 1. 生成MANIFEST.MF文件 -->
       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-jar-plugin</artifactId>
           <version>2.6</version>
           <configuration>
               <archive>
                   <manifest>
                       <addClasspath>true</addClasspath>
                       <classpathPrefix>lib/</classpathPrefix>
                       <mainClass>com.ns.runable.RunnableTest</mainClass>
                   </manifest>
               </archive>
           </configuration>
       </plugin>
       <!-- 将依赖包拷贝到<outputDirectory>${project.build.directory}/lib</outputDirectory>指定的位置，即lib目录下 -->
       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-dependency-plugin</artifactId>
           <version>2.10</version>
           <executions>
               <execution>
                   <id>copy-dependencies</id>
                   <phase>package</phase>
                   <goals>
                       <goal>copy-dependencies</goal>
                   </goals>
                   <configuration>
                       <outputDirectory>${project.build.directory}/lib</outputDirectory>
                   </configuration>
               </execution>
           </executions>
       </plugin>
   
   </plugins>
   </build>

   缺点：生成的jar包太多不便于管理，看下面这个插件：只生成一个包含依赖资源和依赖包的jar;

<build>
    <finalName>kafka_go</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <archive>
                    <manifest>
                        <mainClass>chap2.ProducerDemo</mainClass>
                    </manifest>
                </archive>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
            <executions>
                <execution>
                    <id>make-assembly</id>
                    <!-- this is used for inheritance merges -->
                    <phase>package</phase>
                    <!-- bind to the packaging phase -->
                    <goals>
                        <goal>single</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
