Probably best to just forego all support and leave it to the mailing lists,
much less stressful that way :p

Out of curiousity, do you think that the time may be ripe to set up a
scala-ide mailing list with epfl, we seem to be getting more and more
questions raised about it...

Can we take this as confirmation that 3.5 is now the recommended eclipse
distro to work against?

If so, the wiki needs updating:
http://www.scala-lang.org/node/94

especially the bit about "(3.5 Milestone releases are not fully supported)"
--

*Requirements*

The recommended (and minimum) versions of the components required to use the
Scala Eclipse plugin are,

   - version 6 or newer of the Java Development
Kit(minimum version
   *5*)
   - version 3.4.1 or newer of Eclipse
"Classic"(3.5 Milestone releases
are not fully supported)

It's the read-only installation which was at the root of your problem
with 3.4.2. Upgrading to 3.5 would have also fixed the problem, and
there are also other ways of avoiding have to install the IDE to /opt
but they're somewhat fiddly and system-specific.

Seeing as you're up and running now I'd suggest leaving things as they
are. However, keep this in mind if you upgrade the Scala IDE before
your update to Eclipse 3.5.

Cheers,


Miles

3.4.2 and 2.7.5

Workspace in ~/ and installation in /opt/eclipse-3.4.2. plugins/ and
features/ are writeable to some user I hadn't seen before (no
mnemonic, only a numeric ID), the rest all read only to the user
that's running it.

So I changed my permissions/ownerships on this stuff, because I was
tired, and initially all the manual edits I'd made screwed my eclipse.
By removing all the edits eclipse ran again, but the plugins I'd
installed via update sites had been removed. I reinstalled the scala
plugin, and now it says JDT weaving is enabled, and the original
problem appears solved, so thank you.

Ahem ...

JDT weaving *not* being enabled is your problem.

JDT weaving being enabled is your problem.

What versions of Eclipse and the Scala IDE?

Also is the filesystem layout of your Eclipse install unusual in any
way? Is it read only?

Dunno, to be honest. It says it's disabled but I've done everything it
suggests to enable it (specifically: manually enabling in the
config.ini file and then the contradictory advice at
http://wiki.eclipse.org/JDT_weaving_features ). But it still says it's
disabled.

And as I said it was all working before.
