Epic list!

Thanks for the initiative! Let us know where we can help / simplify things (so the 2.13 upgrade will be smoother ;-)).

Actually, @skyluc, I believe you mean daniel-trinh/scalariform#20 for scalariform above.

[huitseeker]

@skyluc daniel-trinh/scalariform#23 daniel-trinh/scalariform#24 merged, do we need an official release ?

[skyluc]

@huitseeker no. We could use a tag, but it is not critical for the moment. We can build it from master in the nightlies, like we do for scala-refactoring.

#49 is merged, shall we cross if off this list? Any other items that we could tick off?

[adriaanm]

Looks like 2.10.x also hasn't built successfully (first failure: scala/scala#4186, https://scala-webapps.epfl.ch/jenkins/job/pr-scala-integrate-ide/9174/console)

@sschaef @dragos We'd like to prioritize this work so that we can aim to have IDE building with Scala 2.12.0-M5 (scheduled April 25).

Is the big list above still an accurate reflection of the status of the work? Are there any shortcuts that could be taken as intermetiate steps to get at least the core building, e.g. building a slimmer IDE without worksheet, Scalatest, scala-search etc? What help do you need from the Scala team?
