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

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>

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?
