I am developing eclipse plugin projects, targeted to Eclipse 2.1, using
Eclipse 3.0 (M8).
I wanted to use some simple aspects for debugging/tracing support.
The plugin I'm currently working on (let's call it "dev" ) depends
various eclipse plugins (e.g. org.eclipse.ui, org.eclipse.emf etc) and
on other plugins of mine, including a "lib" one that contains all the
library jars I build on (eg log4j concurrent...).
I added aspectJ nature to the "dev" plugin project,
I included aspectjrt.jar (picked from ajdt 1.1.7) in the jars included
with the "lib" plugin.
I wrote a tracing aspect for the "dev" plugin:
---------
public aspect TraceAspect {
pointcut traceable() : !within(TraceAspect) &&
!preinitialization(*.new(..));
int indent=-1;
before() : traceable() {
indent++;
print(thisJoinPoint);
}
after() : traceable() {
indent--;
}
protected void print(org.aspectj.lang.JoinPoint jp) { ...
---------
rebuilt all
and launched the runtime workbench.
It starts up, some tracing takes place (I can see it in the console of
the host eclipse which captures stdout of the runtime WB) but when I
open editor/views that require classes from my plugins, things blow up:
note the last line of the stack I paste below :

any hints on what I do wrong ?

Good news - project now works with ajdt 118.
I shut down eclipse, manually removed the ajdt 117 feature & plugins
directories, unzipped the 118 archive (slow to download!).
Cleaned projects, renamed aspect file to use .aj suffix,
simplified the aspect not to invoke toString() on the args and rebuilt
(feels faster with 118).
all is well ...

Edoardo,
I have a similar project to the one you have described in your posting. I
am developing a eclipse plugin project, also targeted to Eclipse 2.1, using
Eclipse 3.0 GA, and I would like to add some debugging/tracing support to
one or more of the org.eclipse.emf projects. The plugin containing my
aspects depends upon those emf projects compiles successfully modifying the
appropriate emf class files (I also see the aspect class file within the
output jar). I encounter problems when I try running my application in the
Eclipse runtime environment. When the pointcut is encountered in the emf
code I get a java.lang.NoClassDefFoundError exception listing the aspect.
Do the aspects and the code containing the join points need to be in the
same Eclipse project? That would seem to severly limit the power of
cross-cutting multiple projects. How do Eclipse project dependencies and
project classloaders work with aspects and AJDT?
Any help you can provide would be greatly appreciated. Thanks
Dennis Fuglsang

Good news - project now works with ajdt 118.
I shut down eclipse, manually removed the ajdt 117 feature & plugins
directories, unzipped the 118 archive (slow to download!).
Cleaned projects, renamed aspect file to use .aj suffix,
simplified the aspect not to invoke toString() on the args and rebuilt
(feels faster with 118).
all is well ...

Edoardo,
I have a similar project to the one you have described in your posting. I
am developing a eclipse plugin project, also targeted to Eclipse 2.1, using
Eclipse 3.0 GA, and I would like to add some debugging/tracing support to
one or more of the org.eclipse.emf projects. The plugin containing my
aspects depends upon those emf projects compiles successfully modifying the
appropriate emf class files (I also see the aspect class file within the
output jar). I encounter problems when I try running my application in the
Eclipse runtime environment. When the pointcut is encountered in the emf
code I get a java.lang.NoClassDefFoundError exception listing the aspect.
Do the aspects and the code containing the join points need to be in the
same Eclipse project? That would seem to severly limit the power of
cross-cutting multiple projects. How do Eclipse project dependencies and
project classloaders work with aspects and AJDT?
Any help you can provide would be greatly appreciated. Thanks
Dennis Fuglsang
