Re: [aspectj-users] Re: Need help getting AJDT 3.6 + Scala 2.8.0 plugin

[Michael McCray <mike@xxxxxxxxxxxxxxxxx>]

Do you have the Scala class on the inpath of the AspectJ project?
I am wondering if the Scala project is untampered you should be able to work with it, and the aspect project can weave it's own classes

Hi Miles and everyone,

(moving this to ajdt-dev mailing list)

I am just trying to get Scala and AJDT installed on 3.6.  The good
news is that I was able to create a Scala project, a Scala class, an
AspectJ project, and an Aspect that adds an ITD onto the scala class
(and decompilation looks like the build was successful.  However, I
cannot open the Scala editor (or the Scala class file editor).  I keep
getting variants of the following exception.

It could be that the weaving is not working properly, but more likely
it seems that the plugin is referencing a method that no longer exists
in M7.  (This is with the latest nightly build of Scala IDE.)
