Easy Scala with Maven & Eclipse (scala 2.10)

I spent some time to figure this out ... not sold on sbt yet, and I am used to Eclipse 3.7.

So here is the simple procedure :

1. Install the Scala plugin for Eclipse from scala-ide.org. I use this update-site for scala 2.10
2. Install this eclipse plugin for maven / m2e : http://alchim31.free.fr/m2e-scala/update-site
3. You can then import easily a Maven project.
4. Right-click on the project, Configure > Add Scala Nature

Sample maven file :

Add more RAM to Eclipse

Open configuration file eclipse.ini in your Eclipse installation folder, then add more memory, and restart.

--launcher.XXMaxPermSize
512M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx512m

Add -Xverify:none to your eclipse.ini.

Disable Eclipse validators

By default, all code validators are running, go to Windows > Preferences > Validation and uncheck validators you don't need.

Disable Plugins you won't use and startup builds.

Go to Windows > Preferences > General > Startup and Shutdown and uncheck plugins you don't need.
Don't forget to disable startup automatic builds.

Disable Eclipse PDT automatic build

Go to Windows > Preferences > General > Workspace and uncheck build automatically.
