request for feedback : maven + scalacs integration

[David Bernard]

[Sorry to spam lift mailing-list but there is lot of maven + scala 2.7.7  lift users]

Hello,

Before releasing maven-scala-plugin 2.14, I do a call for test/feedback about the following goals:
 scala:cs-init : to register project to scalacs (install and start scalacs if needed)
 scala:cs-compile : to compile your project (and dependencies if modified and registered)
 scala:cs-compile-single : to only compile the project
 scala:cs-remove : to de-register the project from scalacs
 scala:cs-stop : stop scalacs

The 'cs-xxx' goals are about using [ScalaCS][1] and should allow quicker compilation (via a compilation server).

you could also use only the scala:cs-init and request compilation via cUrl or any http client (see documentaion of [ScalaCS][1], there is a basic sample for emacs integration).
I copypast a fragment a session (I used [MavenShell][2], also recommanded for maven command line users, it works with maven2 based projects).

WARNING : scalacs 0.2 (last released) only works with scala 2.7.7
