Install Intellij and the Scala plugin (File -> Settings -> Plugins -> Available).Generate your maven project using the simple Scala archetype:

mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create 
    -DarchetypeGroupId=org.scala-tools.archetypes  
    -DarchetypeArtifactId=scala-archetype-simple
    -DarchetypeVersion=1.2
    -DremoteRepositories=http://scala-tools.org/repo-releases
    -DgroupId=[group]
    -DartifactId=[artifact]

 
--mvn 3.0直接mvn archetype:generate
351: remote -> scala-archetype-simple 
Add the Scala compiler lib to your project dependencies in the pom.xml file:

<dependencies>
    <dependency>
        <groupId>org.scala-lang</groupId>
        <artifactId>scala-compiler</artifactId>
        <version>${scala.version}</version>
        <scope>compile</scope>
    </dependency>
 </dependencies>      

?
Update the Scala version configuration to a recent release:

<properties>
    <scala.version>2.8.1</scala.version>
</properties>
