This is fixed on trunk, which I appreciate might not be all that
helpful to you right now.

2.7.5.final should be compatible with AJDT 1.6.4/Eclipse 3.4.2 and
with AJDT 1.7.0/Eclipse 3.5. I'm afraid all my bandwidth is taken up
with work for 2.8.0, so the chances of there being an intermediate
release are extremely slim.

Hi Miles,

Will this release be in the nightly build update site?

http://www.scala-lang.org/scala-eclipse-plugin-nightly

Cheers,

Miles

Yes, but bear in mind that this is the tip of the development branch
and shouldn't be treated as stable. The IDE is developed in lockstep
with core Scala, so it also includes the tip of the development branch
of the language and standard libraries ... I think it's very unlikely
that that's what you want.

OTOH, it will show you how AJDT compatibility will be handled from
2.8.0 onwards. The Equinox Aspects/JDT Weaving features have been
separated out so that they can be shared between AJDT and the Scala
IDE.

Cheers,

Miles

OK. I will wait for next release, or may hack the metadata locally to relax the dependency constraint.

When do you think the new, 'AJDT friendly' release will be available?

Thanks,

Miles

Simultaneously with the 2.8.0 release of core Scala. Current best
guesses are end September/beginning October for the first release
candidate.

Ok, when we can expect AJDT-friendly nightly build ? :-)

Sounds like plugins depends from AJDT jars.
But really it comes with its own weaving jars.
And is very narrow dependent on their build-id

And those jars do not work on Pulsar (Eclipse 3.5 for Java and J2ME) for Win32
downloaded recently.
Weaving jar runs fine, but hooking jar runs no way, when manually starting from
plugin registry it gives empty-decription error "fragment plugin cannot be
started"

At the same time, MTJ's hooking works ok.
May it be that JDT hooks are mututally exclusive ?

I've downloaded Eclipse + Java w/o J2ME, would look if it makes a difference
but i've doubt.

Currently it just does not work :-/

Bearing in mind that the nightlies are development builds and
shouldn't be relied on to function as you'd expect or even at all ...

... right now. It's the setup I use for developing the Scala IDE itself.

Install AJDT 2.0.0 first, then when you install the Scala IDE don't
select the JDT Weaving feature that it offers: it'll use the one that
was installed along with AJDT.

There's still room for improvement here. I actually don't think I'm
gaining very much from the JDT specific weaving part of the AJDT
feature, really only Equinox Aspects. So I think that before 2.8.0 is
released I'll remove the JDT specific dependency at which point the
overlap is just Equinox Aspects and hopefully that will be easier to
manage.

Cheers,

Miles
