I created a new scala project with the following:
mvn org.apache.maven.plugins:maven-archetype-plugin:2.2:generate -DarchetypeGroupId=org.scala-tools.archetypes -DarchetypeArtifactId=scala-archetype-simple -DarchetypeVersion=1.3 -DgroupId=myGroup -DartifactId=myProject -Dversion=0.1.0 -DinteractiveMode=false
Which gives me the following POM:

I can run mvn test and the test samples succeed. I would like to use the latest version of scala (I downloaded / installed 2.9.2 ...), but the latest version of org.scala tools. testing the scala_VERSION dependency seems to be 2.9.1 . I made changes to my POM:
<scala.version>2.9.1</scala.version>
and
<dependency> <groupId>org.scala-tools.testing</groupId> <artifactId>specs_${scala.version}</artifactId> <version>1.6.5</version> <scope>test</scope> </dependency>
Now running mvn test gives

I presumably have some of the simplest tests (samples created by the maven archetype plugin) and scala's attack on one minor version breaks them? Should I just stick with scala 2.8 until the maven tools catch?
