1.法1：maven打包
pom.xml文件
<plugins> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <appendAssemblyId>false</appendAssemblyId> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive> <manifest> <!-- 此处指定main办法入口的class --> <mainClass>ch.kmeans2.SparkStreamingKMeansKafkaExample</mainClass> </manifest> </archive> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>assembly</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.scala-tools</groupId> <artifactId>maven-scala-plugin</artifactId> <version>2.15.2</version> <executions> <execution> <id>scala-compile-first</id> <goals> <goal>compile</goal> </goals> <configuration> <includes> <include>**/*.scala</include> </includes> </configuration> </execution> <execution> <id>scala-test-compile</id> <goals> <goal>testCompile</goal> </goals> </execution> </executions> </plugin> </plugins>而后应用mvn clean package命令进行打包，如果提交到集群运行遇到Exception in thread "main" java.lang.AbstractMethodError，思考我的项目中spark的版本和集群运行版本是否始终
2.法2：idea打包
Project->Module Setting->Artifacts
而后Build Artifact输入jar包
