Hi,
I have installed AJDT plugin(2.1.1) on eclipse 3.6. I'm trying to apply the AspectJ functionality on my existing code. ADJT is installed correctly and working perfectly. It is able to understand all the existing Aspects etc. Excellient !!
But, when I try to create a new aspect , it is giving an error message asking to view the log. In the log, following is the error.... . Did anyone get this error, is this a bug ? Please suggest. Cannot find any help on the web.

Are you running with jDT weaving enabled? Check Preferences -> JDT Weaving.

Thanks Andrew , but the JDT weaving is already enabled.
Just to give more details, after the error message (asking to see the logs) , an *.aj file is created but doesn't have any template code in it and even if I manually try to write it , outline view and other views are not getting updated.
Please help !

There may be a bug in there somewhere.

Can you attach a simple project where this is failing for you?

As a workaround, you can create a Java class, right click -> AspectJ Tools -> Convert File extension to .aj.

Then change 'class' to 'aspect'.

Hello Girish,

I just started working on AspectJ. I too face the same problem

Did you get any work around other than creating a class and making it aspect ?


My IDE:

Version: Indigo Release
Build id: 20110615-0604

AspectJ: download.eclipse.org/tools/ajdt/37/update

Any pointer in this regard would be highly helpful


Thanks,
Phani

ya .. I didn't get a chance to get back to Andrew on this, but I remember the workaround he mentioned works . Here is what he mentioned.

As a workaround, you can create a Java class, right click -> AspectJ Tools -> Convert File extension to .aj.

Then change 'class' to 'aspect'.
