There's only one Eclipse IDE and it's very much maintained ... that 2.8 branch that you're getting such good results from is precisely the result of that work.

See that ticket ... the JRE classpath container was missing from the generated .classpath. Presumably you fix up .project and/or .classpath file by hand after importing a Scala project using m2eclipse? Apparently m2eclipse would only create correct Eclipse metadata for a Scala project if the Scala IDE implemented an m2eclipse-specific extension point. I don't have time to do that, so unless someone else steps up with a contribution I don't really have any other option than to recommend using something else.

FWIW, after a slightly heated exchange around this Trac ticket, https://lampsvn.epfl.ch/trac/scala/ticket/2226 I've come to the conclusion that m2eclipse should be avoided like the plague currently, and I've updated the Wiki page accordingly. I think I'm right in saying that people are currently getting the best results from using the Maven command line tools and then importing the resulting projects into Eclipse and/or adding the Scala nature manually later? And that if they use Maven-Eclipse integrations at all, it's only after initial project creation?

OK, you have two problem here (which are Scala IDE bugs, so I was a bit harsh on Maven this time around). You have two output folders: the Scala IDE <= 2.7.5.final only supports one. Use a single default output folder. You also have source directories nested below the top level of your project. Although I've seen reports that this works from various people, there's code in 2.7.5.final and earlier which makes this unlikely. If switching to a single output folder doesn't solve your problems try also moving your source directories to the top level. Both of these issues are fixed on trunk (but don't go there unless you're using the Lift 2.8.0 branch). Let me know how you get on ...

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.

Unsurprisingly I disagree. Bug reports and more contributions to documentation on using Eclipse with Lift and Maven would be much appreciated from the Lift community. There's a start here, http://lampsvn.epfl.ch/trac/scala/wiki/ScalaEclipseLift http://lampsvn.epfl.ch/trac/scala/wiki/ScalaEclipseMaven but clearly a great deal more is needed.

Isn't the source of object scala.util.Random from 2.8.0 good enough?
// Backported to collections < 2.8.0

val buf: Array[T] = seq.toArray

buf(i1) = buf(i2)
buf(i2) = tmp
}
for (n <- buf.length to 2 by -1) {
val k = nextInt(n)
swap(n - 1, k)
}
buf.toSeq
}

Other than the change to the Scala distribution that's bundled with the IDE there are no changes in 2.7.5, so the only thing you'd be missing out on would be the actors changes (tho' I think that's enough of a reason to want to upgrade).

Is anyone willing to write this up for the Scala Trac Wiki? A walkthrough of getting a Scala GAE project up and running in Eclipse would be extremely helpful. While we're about it, the current Wiki entry for using the Scala IDE for Eclipse for Lift development consists of exactly one line. While I'd be delighted if things really were as simple, straightforward and reliable as that implies, I fear that in fact the picture isn't so rosy. It'd be fantastic if someone could also contribute a walkthough of setting up a Lift project in Eclipse.

[Lift] Scala IDE for Eclipse: Expect a little turbulence on trunk ...
Hi folks, I'm at EPFL for the next two weeks for an intensive hacking stint with Martin and Iulian on the Scala IDE and on scalac's IDE interface. For now I would strongly recommend staying well away from trunk if you want to be able to get any useful work done: things are currently broken and are likely to get worse before they get better. We have some very ambitious (but realistic) plans for this fortnight, and I think that by the beginning of June we'll have made an awful lot of progress on both stability and features, and will have opened things up for much more rapid improvement in the future.

Very intuitive eh? Can't that workaround be made the default behaviour for Maven Scala modules? At least then things would work out of the box with Eclipse (if I'm understanding the situation correctly). TBH, I'm a little bit cheesed off to discover that lots of the alleged brokenness of the Scala IDE for Eclipse seem to boil down to Maven trampling all over internal Eclipse metadata.

These issues all relate to the way that Scala is presented to the
JDT's indexer ... there are a lot of deficiencies here, I know ... if
you're on trunk at the moment you should see fairly rapid improvements
between now and the release of 2.8.0.

Hmm ... these should be pretty much fully functional both on trunk and
the upcoming 2.7.4 ... if you have reproducible examples of these
kinds of issue could you create tickets for them in the Scala Trac
with the component set to "Eclipse plugin".

Miles

Yup, AspectJ can only advise Java classes. Seeing as it's Aspect*J* the advice itself is essentially written in Java. But advice can call Scala code, so it's possible to do most of any heavy lifting in Scala. FWIW, my attitude to AOP used to be the same as David's: I thought it was evil because ... it represents a gross violation of encapsulation and modularity and is the moral equivalent of INTERCAL's COME FROM (http://en.wikipedia.org/wiki/COME_FROM). I've now seen the light and realize that AOP is wonderful because ... it gives me all that tools I need to grossly violate the encapsulation and modularity of the JDT ;-) I would say that you should consider AOP when all of the following conditions are met, * You need to change the interface/behaviour of a third party component. * You can't persuade the third party to accomodate you. * You have access to the source code of the component. * Forking, replicating or replacing the component would be too painful. * You are able to commit to tracking changes in the component to accommodate the inevitable breakage of time as it evolve independently. This happens surprisingly often (except maybe the last), both wrt open source and internal enterprise projects, which goes a long way to explaining the success of AOP as a model.

While you're right in a (very) narrowly technical sense you're missing the point that Lift's Can has functionality that is very closely related to a combination of Option and Either in a touchy-feely pragmatic getting-useful-things-actually-done sort of sense. To prove the point, here, http://www.milessabin.com/misc/Chain.scala is something I put together a while ago which can be used in a very similar way to Can (at least, I expect that's the case ... I haven't worked with Lift so I can't be sure) but which only exposes Option and Either in it's public interface. It's also sufficiently Monad like to get along nicely with for comprehensions. Given the likelihood of confusion between Can and Option (irrespective the algebraic niceties) I wish Lift had gone for something more like that than a rename to Box.

This is pretty minor tho' ... Eclipse is just showing a subset of the errors in a known to be non-compiling project. I agree things should be better, but you'll find that as you fix the errors in your project the set of errors that Eclipse is reporting will converge to the true set of errors. > My top lame excuses for not creating a bug earlier were that: > 1) I was hoping it would get fixed in the next snapshot :) since it did > doesn't seem like something that's specific to my project See above.

Yes, there are many JDT features which aren't yet wired up to the Scala plugin properly, but if you just ignore them things should work fairly smoothly. In particular cleaning all projects should work just fine.

My understanding is that Lift on 2.7.2 is still a work in progress, so seeing as the Eclipse plugin requires 2.7.2 it might be early days for that combination. As ever I'm keen to make the Lift and Eclipse experience as pain free as possible, but as ever I need help from the Lift community.

You can turn off automatic building in Eclipse, but this only get's you so much. Many of the semantically sensitive features of the Eclipse plugin are dependent on the underlying Scala compiler infrastructure, and this has version sensitivities. This is unavoidable in the absence of an independent mechanism for making that information available to an IDE. It's worth bearing in mind that Eclipse and Netbeans are on the same footing now that Netbeans is also using the same compiler infrastructure. So I'm afraid that for the foreseeable future you'll have to match the versions of the command line tools you use with the versions of the IDE plugins you use (both Eclipse and Netbeans) if you want their full functionality to be available.
