I am trying to create a Java-Scala maven project. I am using intellij 15 and I add scala archetype to maven project. When it tries to generate the pom, it gives error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.2:generate (default-cli) on project visualizer: The desired archetype does not exist (org.scala-tools.archetypes:scala-archetype-simple:1.2) -> [Help 1]

Here is my pom, 

 <project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>application</groupId>
<artifactId>visualizer</artifactId>
<version>1.0-SNAPSHOT</version>
 </project>

I have added scala archetype while creating maven project.

How should I fix this?

Here is a full pom.xml skeleton for a hybrid Java/Scala project:

Thanks. It worked on my personal laptop. Now I just need to the same steps in my official project. By the way, if I have to specify java and scala source folders, how do I do that in a single maven execution xml?
You do not need to specify if you use the default directory tree.
If I use artifactId scala-compiler:2.11.8, what all do I need to change?
I am trying to run this pom file without all the scala test artifacts, but it gives error for scala library 2.11.4. I will try to add the dependency manually and see how far it goes.
The experiment failed. I manually added the following dependencies: scala-library-2.11.4.jar scala-library-2.11.4.pom scala-compiler-2.11.4.jar scala-compiler-2.11.4.pom scala-reflect-2.11.4.jar scala-reflect-2.11.4.pom commons-exec-1.0.1.jar commons-exec-1.0.1.pom snakeyaml-1.4.jar snakeyaml-1.4.pom jackson-core-asl-1.6.1.jar jackson-core-asl-1.6.1.pom jackson-mapper-asl-1.6.1.pom jackson-mapper-asl-1.6.1.jar but it looks like a nested dependency that keeps going to previous versions.
