Question

I am using Scala IDE for creating a maven project with spark
1.I have created a maven project with skipped the archetype and added the following pom file.

Answer 1

Go to this location
c:\users\Nivedita.m2\repository\org\apache\hadoop\hadoop-common\2.6.0-cdh5.8.2
and try deleting hadoop-common-2.6.0-cdh5.8.2.jar file and do maven build again.

Answer 2

Can you try with an recent version of scala plugin ? (it's the successor of the one you used, I'm the author of both)
<plugin>
<groupId>net.alchim31.maven</groupId>
<artifactId>scala-maven-plugin</artifactId>
<version>3.3.2</version>
</plugin>
(see http://davidb.github.io/scala-maven-plugin/example_java.html)
if you use a jdk 9+ to compile (regardless of jvm 1.8 in the config) you can have this kind of issue. So check that the jdk is 1.8 .
