Hi,
I've just started trying out the AspectJ plugin for eclipse and I'm having
a few problems which may be installation/setup issues or (more likely)
it's me not 'getting it'. I installed the plugin and followed the
post-install instructions in the ajdt directory. I then decided to try
and follow chapter 1 of the developer's manual from the main AspectJ
website. I created an AspectJ project and then created the Point class
and then created an aspect class and put in a simple pointcut for the
'setters' and an 'after' to print a message that something had been set.
I then clicked on build and got the following message:
"Compile could not complete. See the console for more details..."
I'm not sure what console this is referring to. I've checked the console
view and the .log file but couldn't see anything. Anyway it had changed
my source, but I thought the aim of this approach was that it didn't
change my source code, rather it created a temporary .java file and
compiled that, mixing in the aspect code. To attempt to rectify this I
then looked through the project properties and setup a new working
directory (d:\temp) and reset the Point.java file back to it's original
state. I built again and it gave the same message. Looking in the temp
directory it had created the .java file but not the .class file. In fact
I couldn't find a .class file anywhere, so I guess the message is
referring to that. The .java in the temp dir had the interleaved code in
it.
I'm now going to try and run the examples by hand using the command line
tools to see if I can see where I'm going wrong but just thought I'd give
you feedback on a 'complete newbies' experience of the plugin. As I said
it's probably me not understanding how I'm supposed to set up a project.
Any help/advice would be gratefully accepted!
Thanks,
Dave Watkins

CLASSPATH=D:\eclipse\plugins\org.aspectj.ajde_1.0.6\aspectjr t.jar;D:\eclipse\jre\lib\rt.jar;D:\eclipse\plugins\org.aspec tj.ajde_1.0.6\aspectjrt.jar;D:\eclipse\workspace\TestAspectJ ;
11:06:33 Model update notification for TestAspect.java
Which isn't giving me any clues!
Thanks

As is usually the case in these matters I decided for one last attempt at
sorting things out and have got to the point where it seems to be sort of
working! I created a new project ("TestAspectJTarget") and set the
aspectJ working directory preference of the source project ("TestAspectJ")
to that. I added the aspectJ runtime library to the build path of the
target project and then clicked on the build in the source directory. I
still get the warning message but when I clicked refresh on the target
directory it seemed to compile everything okay, running my Point class
then displayed the correct output!
I'm now out of the starting blocks and away! But I still suspect that
I've just come up with a workaround rather than the 'proper' way of doing
this.
Thanks,
dw

In a bid to get the longest running one-man thread I thought I'd post and

'Use javac to compile .class files' option in the project preferences.
Deselecting this made the error message go away and everything seems to be
working, and I must say I do like what I see!
Anyway, hopefully this may save someone else from spending a few hours (I
know I'm slow) puzzling over this. It does of course beg the question
what this option is for... but that's not important to me now ;)
Regards,

Hi Dave,
I'm glad that you got things working. You're not the only to get confused
about the "use javac" option, and there seems to be a bug with it since you
saw the "Compile could not complete" report. I'll submit a bug report on
your behalf. We'll also explore a way to better inform the user when no
..class files will be generated, e.g. with a dialog after the option is
selected.
Regards,
Mik
