生成可运行的jar包

1、首先在pom文件中拷贝以下内容：
<!--设置启动项的类名称，依赖包的路径，必须的-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
    <archive>
        <manifest>
            <mainClass>Kafka.MainRunner</mainClass><!---->
            <addClasspath>true</addClasspath>
            <classpathPrefix>lib/</classpathPrefix>
        </manifest>
    </archive>
</configuration>
</plugin>
<!-- 把依赖的jar包拷到lib目录下，必须的 -->
<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>${project.build.directory}/lib</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
        </execution>
    </executions>
</plugin>
<!-- 以utf-8编码拷贝配置文件，拷贝过程中是可以做变量替换的，也就是说你的配置文件可以是个模板，里面的${}所包含的内容是可以拷贝过程中替换的，非必须的 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.3</version>
    <executions>
        <execution>
            <id>copy-resources</id>
            <phase>package</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <encoding>UTF-8</encoding>
                <outputDirectory>${project.build.directory}</outputDirectory><!-- 把配置文件拷到和jar包同一个路径下 -->
                <resources>
                    <resource>
                        <directory>src/main/resources/</directory>
                        <includes>
                            <include>config.xml</include>
                            <include>log4j.xml</include>
                        </includes>
                        <filtering>true</filtering>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>
<!-- 打jar包时需要把配置文件给排除在外，非必须的 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>jar</goal>
            </goals>
            <configuration>
                <classifier>lib</classifier>
                <excludes>
                    <exclude>config.xml</exclude>
                    <exclude>log4j.xml</exclude>
                </excludes>
            </configuration>
        </execution>
    </executions>
</plugin>

2、将生成的包和lib文件夹复制到部署目录
3、切换到部署目录，执行:java -jar **.jar
