Re: [scala-ide-dev] how to debug ajdt advice ?

[Jin Mingjian]

ajdt has debug tooling support, I used it for simple sources. But I have not chance/timeslot to confirm it for scala-ide.

2010/7/3 David Bernard <david.be...@gmail.com>

Since I enable Scala/AJDT in my main eclipse 3.5 configuration ? I've
got some NPE on pure java project.
It's very annoying.
I would like to investigate and fix the issue (if possible). But I
didn't found (fulltext search the advice/joinpoint into
org.scala-ide.sdt.aspects)

Some advice (not a wordplay) ?

This looks like advice provided by
org.eclipse.contribution.weaving.jdt which is one of the bundles we've
borrowed from AJDT. If you grab the source from the AJDT update site
you should be able to find the advice on RenameJavaElementAction and
set a breakpoint on it.

Cheers,

Miles
