2. Installation

2.1. Eclipse Scala plugin

You can use this update site http://www.scala-lang.org/scala-eclipse-plugin to install the Scala Plugin for Eclipse. See Eclipse Update Manager for using the update manager.

2.2. Enable JDT Weaving

You need to activate the JDT Weaving. Select Windows -> Preferences -> JDT Weaving and press "Enable". A restart of Eclipse is required.

Tip

I faced the problem that I could not activate the JDT Weaving. Once I uses a "fresh" installation of the Eclipse Java IDE it started to work. I assume another Plugin interfered with the settings.
