Hi Matthew,
I am sorry about the confusion. I mixed up project A and B in my last
email. Here is the situation:
- Project A is org.eclipse.core.resources that I have converted to an
AspectJ project. It references some classes in Project B.
- Both classes in Project B and aspects in Project A are referring to
certain static variables in Project B's classes.
- I am using Eclipse 3.2
- I do not see a META-INF/MANIFEST.MF file for org.eclipse.core.resources,
in the workspace directory.
- All the manifests and bundles are found at: <workspace>
\.metadata\.plugins\org.eclipse.pde.core\New_configuration\org.eclipse.osgi\manifests
or \bundles
- I am attaching my version of the org.eclipse.core.resources manifest
here. The project B, that I am talking about is
"com.ibm.wbit.performance.monitoring".
- If I add com.ibm.wbit.performance.monitoring to the classpath, it works
fine, but I have to create a separate jar file for
"com.ibm.wbit.performance.monitoring" that must exist in
org.eclipse.core.resources directory, for the jar file to be loaded inside
of Eclipse. This leads to 2 versions of the
"com.ibm.wbit.performance.monitoring" classes- 1 inside the original
project and one in the jar file for org.eclipse.core.resources.
(See attached file: org.eclipse.core.resources_3.0.1.MF)
I really appreciate your help.
Thanks.

Irum,
I am now completely confused. In one post you say Project A depends on B
and now you say that aspects (which I presume you wrote) in Project B refer
to classes in A. Eclipse PDE doesn't support recursive references like
these. I also don't understand your reference to manifests. Every Eclipse
plug-in is a bundle and has a manifest META-INF/MANIFEST.MF including
org.eclipse.core.resources. Can you be much more specific about the version
of Eclipse you are using, the bundles you are working with and what you are
trying to do.

Hi,
I just wanted to let you know that I tried the same situation with 2
arbitrary projects and I could not reproduce the problem. However, in my
original case the project B is org.eclipse.core.resources, which has some
aspects in it that refer to classes in Project A. I get this problem in
this specific situation and am not sure how to resolve it.
Thanks.

Hi Matthew,
Thank you for your response. After reading your response, I realize that it
is not exactly an AspectJ problem since project A only needs classes from
project B. However, I am still not able to resolve this problem. This is
what I observed:
- The manifest file is only generated for plugins that are not open in the
development workspace. Since project A is under development, there is no
manifest file generated for it in the \org.eclipse.osgi\manifests folder.
- I removed the project from the development space and realized that I
would have to add project B's class (as a .jar file ) in the class path in
the manifest file for project A.
For that reason, I tried the following:
- Assume class C is the class in project B that is needed by project A.
- Class C has some static variables that are set in by method calls inside
of Project B, but read by aspects in Project A.
-To resolve the run time issue, I exported class C into C.jar and added a
reference to C.jar on A's classpath - which also adds it to the manifest.
The problem now is that the copy of class C used by project B and project A
become different due to C.jar reference in project A. And so the static
variable being set in project B is different instance of the same static
variable being read in Project A.
Adding an entry in the manifest file would have the same issue, since I
need a .jar reference.
I am not sure what I am doing wrong and how else to add the .jar reference
in Project A, but maintain the exact same copy of reference in Project B. I
will appreciate your response.
Also, since this is not an AspectJ issue, please let me know if I should
follow up on this on a different forum.
Thanks for your response.

Irum,
Are you using Eclipse, if so which version? In Eclipse 3.0 and later
plug-ins are OSGi bundles so it is the manifest that is used to determine
and resolve dependences. In your cases any packages that contain classes
that are needed outside of the project B will have to be exported while the
manifest for project A must state that it requires B. What functionality
does project A require from B, is it just classes or aspects as well? I am
not sure if this is an AspectJ problem or an OSGi meta-data issue.

[aspectj-users] AspectJ errors
in plugin projects.
Please respond to
[email protected]
Hi,
I have an AspectJ plugin project (A) that is using functionality from
another plugin project (B). I have added B's source folder under A's
Aspectpath and inpath. I have also added a plugin dependency on B in A's
plugin.xml file.
When I run the plugin A, I get the following error:
java.lang.NoClassDefFoundError: B.ClassC
The "ClassC" is declared inside of plugin B. If I add a B.jar on the A's
classpath the error disappears. The problem is that I can only add a .jar
file on A's classpath that is copied in project A. As a result, I end up
with two versions of ClassC.
The project B refers to a different ClassC than the plugin A. Since I am
relying on some static data in ClassC, I am not sure how to maintain one
version of ClassC and link it to my AspectJ project and run it.
I will appreciate your response on this.
Thank you.
