问题
I have developed a standalone spark scala application which uses SparkSQL and SparkStreaming.
This works fine in Eclipse which is configured for spark.
I am newbie in maven.
To package this application using maven, I have followed the below tutorial
http://ryancompton.net/2014/05/19/sample-pomxml-to-build-scala--jar-with-dependenciesjar/
But ended up with the following error.

Please provide a solution on how to package my application and run in cluster.
回答1:
I use sbt as my package and compiling tool. With sbt, I use "assembly" plugin to package dependencies in the final jar file. I recommend it.
If you maven, I believe "shade" plugin do the similar job. See the usage page of shade and you will be inspired. http://maven.apache.org/plugins/maven-shade-plugin/usage.html
Basically, you need to change the "build" part in your pom.xml file as this:
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<configuration>
<!-- put your configurations here -->
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
...
</project>
