Getting exception Lscala/reflect/api/JavaUniverse$JavaMirror; - scala

Question

I did some research on this and it seems it is due to some version mismatch. I am trying to resolve this from quite some time and not sure the fix. Any help is greatly appreciated.
This is my pom.xml
<properties>
<scala.version>1.6.2</scala.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.11</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.11</artifactId>
<version>${scala.version}</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-mllib_2.11</artifactId>
<version>${scala.version}</version>
</dependency>
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>2.11.8</version>
<scope>compile</scope>
</dependency>
</dependencies>
This is the maven scala plugin configuration which I am using:
<plugin>
<groupId>org.scala-tools</groupId>
<artifactId>maven-scala-plugin</artifactId>
<version>2.11</version>
<executions>
<execution>
<goals>
<goal>compile</goal>
</goals>
</execution>
</executions>
<configuration>
<scalaVersion>2.11.8</scalaVersion>
</configuration>
</plugin>

Answer 1

Can't reproduce. I created Maven project with your pom.xml. Then I ran standard WordCount. It worked fine.
Could you be more specific what you're doing?
By the way have you checked previous answers for this exception?
