Hi Jay,
To which jars are you referring? Does scala have a Maven coodinate? As
it stands I am compiling with.
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>2.10.2</version>
</dependency>
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-reflect</artifactId>
<version>2.10.2</version>
</dependency>
