maven打jar包运行main方法

pom文件添加上这段 

<build>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-pluginartifactId>
                <configuration>
                    <appendAssemblyId>falseappendAssemblyId>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependenciesdescriptorRef>
                    descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>com.buba.kafka.stream.ApplicationmainClass>  
                        manifest>
                    archive>
                configuration>
                <executions>
                    <execution>
                        <id>make-assemblyid>
                        <phase>packagephase>
                        <goals>
                            <goal>assemblygoal>
                        goals>
                    execution>
                executions>
            plugin>
        plugins>
    build>

就会在项目的根目录下的target目录里生成jar包
