I should amend this. Miles Sabin has helped me get Eclipse mostly
working. It does still spew errors when creating projects and has some
weird issues where spurious error markers are shown in the editor that
disappear when the file is re-opened, but otherwise it works and I can
edit Scala code. Miles tells me that these problems will be fixed for
the 2.8.0 release of the plugin.

In its favour, it does seem to do a better job of type introspection and
code completion than NetBeans, especialy in a Scala project referencing
Java classes from an external JAR.

Ciao,

Hi,

I'm managing to be quite productive with Eclipse (Scala plugin 2.7.5
final - despite small bugs) bridging dependencies from SBT into an
IvyDE container. Getting rid of Maven plugins actually improved the
overall experience, and having fine control from an (external) SBT
console works better for me.

For those who are interested this is a good place to get started:

Unfortunately that's a versioning conflict between AJDT 2.0.0 and the
Scala IDE 2.7.5.final ... it's fixed on trunk (but I still wouldn't
recommend using trunk for day to day work) so will be resolved in the
2.8.0 release.

Cheers,


Miles

Hi,

Any news concerning the new 2.8 Eclipse Scala plugin?

I was successfully working with 2.7.5-final, but lately it has been
getting unbearably slow - a total blocker (Eclipse sometimes hangs and
it once even broke my workspace).

Is the 2.8 branch still unstable, would it be too risky to grab the
nightlies? Is there any roadmap?

Thanks,

Francisco

If you get Eclipse hangs during builds with 2.7.5 or earlier, try
quitting Eclipse, deleting your projects .manager directory, then
restart Eclipse and do a clean build.

Not ready yet, but getting there ... watch this space.

Cheers,
