Introduction

There are several different methods for using Scala + Maven with Eclipse.

Existing Java/Maven Project

If you have an existing java/maven project, you must do three things:

1. Install the scala eclipse plugin
2. Right click on the project. Go to the Scala Menu and select "Add Scala Nature"
3. Update your pom.xml to use the maven-scala-plugin and depend on the scala-library like in the pom shown below. <project> ... <dependencies> <dependency> <groupId>org.scala-lang</groupId> <artifactId>scala-library</artifactId> <version>2.7.2</version> </dependency> ... </dependencies> ... <build> ... <plugins> ... <plugin> <groupId>org.scala-tools</groupId> <artifactId>maven-scala-plugin</artifactId> <executions> <execution> <goals> <goal>add-source</goal> <goal>compile</goal> <goal>testCompile</goal> </goals> </execution> </executions> </plugin> ... </plugins> </build> ... </project>
