• Scala IDE Development Guides und Setup: http://scala-ide.org/docs/dev/index.html
• Guidelines: Strategic Scala Style https://lihaoyi.github.io/post/StrategicScalaStylePrincipleofLeastPower.html (bei Gelegenheit mal Lesen, ev. mit ein wenig mehr Scala Praxis)

Build

• Maven Tycho to build Eclipse plug-ins Übersichtsseite: https://wiki.eclipse.org/Tycho/Reference_Card
• Using plain jars in an Eclipse plug-in, so könnte z.B. die Scaps-Libraries integriert werden: https://github.com/scala-ide/scala-search/blob/master/org.scala.tools.eclipse.search/pom.xml (Achtung, dieses "Scala Search" hat nichts mit unserem zu tun!)
