m2eclipse-scala

With m2eclipse and m2eclipse-scala you don't need to define maven-eclipse-plugin's configuration (you should avoid using both)

Features

m2eclipse-scala is a work in progress to ease integration between m2eclipse and scala-ide for eclipse.

What m2eclipse-scala do automaticly (on import / re-configure) ?

• add scala nature to project if maven-scala-plugin is used in the pom.xml => add Scala-Library container
• auto add src/main/scala and src/test/scala
• remove of scala-library, scala-compiler, scala-dbc, scala-swing from Maven Dependencies Container (under eclipse only, you should not have 2 version of scala-library in the classpath)
• re-order JRE Container and Scala Container (to avoid scala.ScalaObject NotFound and C° when use Run As Scala Application)
• add Scala-tools.org catalog

Support

• issue tracker : m2eclipse-scala at assembla
• mailing-list : scala-ide-user

Install

1. install m2eclipse
2. install m2eclipse-scala itself :
   • by dowloading the lastest version of the plugin into your eclipse/dropins directory
   • or by update-site : http://alchim31.free.fr/m2e-scala/update-site/ can change in the future (you can also use the dropins directory see below)
3. Eclipse : File > import > maven > Existing Maven Project ...

If your project doesn't list Scala Libraries in Build Path (or in Package Explorer), try :

• select project
• right click > Maven 2 > Update Project Configuration

Working configuration

The plugin is validated by importing the samples projects into Eclipse:

• Scala Only (no java)
• Scala depends of some java code
• Scala and Java cyclic dependency (configuration longer than mono direction scala -> java or java -> scala to compile under maven)
• Java main code and Scala for test
• Custom Layout java + scala cyclic dependencies, java+scala under the same source folder src and test (for test source folder).
• Lift based project created from a shell created + imported project (used lift-archetype-basic 2.0-scala280-SNAPSHOT)
