The problem is not Eclipse 4, but JDT 3.8.  You're right that AJDT should probably allow for most components of e4 to be installed, but JDT 3.8 is not compatible with AJDT.  I created a patch to fix this, but haven't done extensive testing.  I'll have to do a little bit of work to see if I can avoid making a branch for the new version of AJDT.

Thanks for the info.  I started to dive into the AJDT code to see where the issue was, but I found the learning curve for building AJDT a bit too  steep (or instructions are out of date).  If you have a test build (or a pointer to up-to-date build instructions), I'd be happy to lend a hand.

Patch to get AJDT working on Eclipse 4.2.

If you have AJDT checked out, then you can apply this patch.  See if this works for you.  Let me know what your experience is or if you have any questions or problems applying it.

An update here...I am doing the migration to get AJDT working on JDT 3.7.1.  It turns out that most of the changes required for 4.2 are also required for 3.7.1.  I decided to make all of the changes required so that AJDT is installable on anything from 3.7.0-4.2M1.

I have committed the changes, but haven't done any extensive testing.  When the build goes through, you can try this out on the dev build.  I'll post here when it is available.

A warning, though.  It is likely that internal APIs will change significantly until the final release of 4.2.  So, there may be some issues on any milestone after M1 since AJDT requires the use of many internal APIs.  That being said, I'll try to keep things up to date, but there are no guarantees until the final 4.2 release.

AJDT build is now available that should install on Eclipse 4.2.  Please let me know if this works for you.

Thanks very much for the response.  Unfortunately, I haven't had much luck.  I'm sorry for not responding sooner, but I've been too wrapped up in other work to describe my progress.  Here goes...

I've tried the update site:	http://download.eclipse.org/tools/ajdt/37/dev/update
I get the following error when trying to install "AspectJ Development Tools":

Looking at the error message, It doesn't look like the patch you posted has been applied.  In particular, from my reading of the error message, the requirement from the patch: 
org.eclipse.core.resources;bundle-version="[3.6.0,3.8.0)" 
Isn't present in the development build.

Am I using the correct update site, or is there something I'm missing in the error message?

I tried the zip files from 10-03, 10-04, and 10-18.  Those failed as well.


So I decided to try your patch, and build AJDT myself.  Unfortunately, this is not a very straightforward process (at least, I can't find documentation that works for me).

I tried downloading the source using the Team Project set file:  Ajdt35ProjectSet.psf as described here:
http://wiki.eclipse.org/AJDT_Developer_FAQ#Setting_up_your_workspace_for_AJDT

That didn't work.  That file specifies extssh for the connection, which (if my ancient CVS memory is correct) doesn't allow anonymous access.  Changing the entries to in the file to use pserver instead of extssh didn't work either.  

So, I downloaded the whole org.eclipse.ajdt/AJDT_src/ tree manually (without the project set file).  But I don't know what order the subtrees must be built in, or how to proceed.  I can apply the patch, but after that, I'm pretty lost as far as building my own AJDT.

Sorry if I'm being thick here.  I've only built rather small Eclipse plugins up to now - nothing nearly this large.   I don't know if I'm missing something that's really obvious for someone that builds these things all the time.

Version 2.2.0.e37x-20111215-2200 installs and works just fine (the visualizer display looks broken, but that's another issue).  Thanks for fixing!
