Its final version

Scala IDE for Eclipse V.2.0.1

Yesterday the Scala IDE team for Eclipse announced the final release of V2.0.1, a mere few weeks since its last update; at least it keeps the news following here at JAX! Last month we drew attention to the first milestone for Scala IDE, showing the direction the team wanted to go. On the Eclipse website they commented:

“While the goal of V2.0 was to provide a reliable environment for your Scala coding, with V2.1 we want to bring your Scala development experience to a whole new level.”

So what is new in the V2.0.1?!  Well, according to the release, in 2.0.0 the IDE delivered better incremental compilation by building on the Sbt incremental compiler -- this was all well and good at the time but now there is definitely no need to stick with that version, because with the 2.0.1 they have improved on the Eclipse builder by following Sbt more closely when dealing with dependent projects.

This isn't overly surprising, it just means that when "a project has build errors, dependent projects are not rebuilt and fine-grained information about changes in a project is propagated to downstream dependent projects." This leads to less files being recompiled, the 2.0.1 version compiles exactly the same number of files at the command line Sbt.

For those of you getting caught out by those annoying little editor issues in the previous version your knight in shining armour, so to speak, is Eclipse 2.0.1, as the blog goes on further to discuss:

“We fixed a couple of small, but annoying editor issues: double braces are inserted and deleted together, completions that need an additional import won’t mess up the file, and Open Declaration works when called from the contextual menu.”

If you were hoping for compiler improvements, then you’re in luck as this release is based on Scala 2.9.2 and includes improvements on the way compiler plug-ins are loaded, including the continuations plug-in. This allows the user to have several compiler plug-ins loaded next to each other. This makes life way easier for the user.

This certainly is good news! For those of you who want to go through every little change that has happened in this version, you can do so by clicking here.
