Missing helpful error marks in AspectJ editor [message #53584]

Hi,

I moved my aspects to a separat AspectJ project, so my java projects
contain java code only and AspectJ project contains AspectJ code only.

Now when I compile the AspectJ project, I see compile errors in the
[Problems] tab, but no error marks show up in the AspectJ editor. I used
to see the errors marks in AspectJ editor when I mixed java code and
AspectJ code in a single project. How can I get it back again?

Another little problem I am having is, I extend a concrete aspect to
create another aspect. In AJDT, I do not get any error or warning message.
But if I build the project from the ANT script, I get a "cannot extend a
concrete aspect" error. If AspectJ does not allow extending a concrete
aspect, shouldn't AJDT fail the compile?

Harry

Hi Harry,

Sorry for the delay. Are you still having problems with this? If so,
please raise a bug and we'll investigate further. Please include your
eclipse and AJDT version numbers.

The AspectJ programming guide states: "It is an error for a concrete
aspect to extend another concrete aspect". You should of course get the
same error in AJDT - what version are you using? Maybe this is related to
the first problem.

Regards,

Matt.

Hi, Matt

I still have the first problem. No error marks on AspectJ editor, there's
a red mark on the AspectJ project node though. And the error message in
the [Problem] tab only has project name and line number, no source file
name.

AspectJ compile option is set to "no weave".

Eclipse Version: 3.0.2
Build id: 200503110845
AJDT Version: 1.2.0
Build id: 20050610
AspectJ version: 1.5.0M2

The second problem might be a false alarm. I get the error message in the
[Problem] tab now. (So far so good. I do not want to downgrade back to
Eclipse 3.0.1 and AJDT 1.2 build 20041216 to check this out.)

Thanks very much.

Harry

Hi Harry,

This problem sounds like that reported in bug 82341:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=82341

Are you using filesystem links on Linux? That seems to be one source of
the problem, but it has been seen on Windows too.

I've just increased the severity of the bug - we need to get to the bottom
of this, but we haven't been able to reproduce it ourselves. If you can
show the problem in a simple testcase, please attach it to the bug report.

Regards,

Matt.

Well, I will add the follwing comment to the bug report after I get my
account.

My environment:
Win2K
J2SE1.4.2_05
Eclipse 3.0.2 Build id: 200503110845
AJDT 1.2.0 Build id: 20050610

I had no problem to have error marks and warning marks in AspectJ editor
for a while when I was using Eclipse 3.0.1 and AJDT 1.2.0 Build id
20041216, and having java code and AspectJ code in the same AspectJ
project.

Later I separated java code and AspectJ code, so that java project only
has java code and AspectJ project only has AspectJ code; and then upgrade
to Eclipse 3.0.2 and AJDT 20050610.

Cannot remember exactly when I started having this problem, but I could
reproduce the problem with a standalone AspectJ project containing one
java class and two aspects attached below. The java code is warning marked
and error marked in the java editor, but the AspectJ code are not.

Removing the aspectJ nature from the project, the java class is warning
marked or error marked in the Package explorer, as well as the packages
and project containing the class.
(NOTE: auto-rebuild of converting the project nature does not work
properly as before, or no re-build actually happened? I have to do a clean
build after removing AspectJ nature to get everything right.)

Converting the project to AspectJ project, the marks in the Package
explorer are all gone, except the project node. project name and line
number are in the [Problem] tab, but no source name.

------------------------------------------------------------ --
MyClass.java:
------------------------------------------------------------ --

package pdi.network;
import pdi.util.App;
public class MyClass
{
void myMethod() {}
}

------------------------------------------------------------ --
MyConcreteAspect.aj:
------------------------------------------------------------ --

public abstract aspect MyConcreteAspect {
static int i = 0;
public MyConcreteAspect()
{
MyClass myClz = new MyClass();
myClz.doSomething();
}
}

------------------------------------------------------------ --
MyExtendedAspect.aj:
------------------------------------------------------------ --

package pdi.network;
import pdi.network.MyConcreteAspect;
import java.io.File;
public aspect MyExtendedAspect extends MyConcreteAspect {

pointcut callMyMethod(MyClass myClz):
target (myClz) && call (* myMethod());

pointcut callYourMethod(YourClass urClz):
target (urClz) && call (* yourMethod());

before (MyClass myClz) : callMyMethod(myClz)
{
myClz.prepare();
}

after (YourClass urClz) : callYourMethod()
{
urClz.pack();
}
}

This morning, my Eclipse IDE crashed. I almost lost all menu items from
the Run and Search menu. So I wiped out the .metadata directory from my
workspace directory and spent the whole morning to import and resync my
projects with CVS repository.

Now I get the Run and Search menu recovered, projects re-synchronized with
CVS repository.

Unexpectedly, the error and warning marks reappear in the editor after the
aj files saved and auto-build run, the problem tab linked with the .aj
source line again, just as I thought it should before the crash. I did not
do funcy customized setting, just re-import a java project to workspace
and re-sharing an aspectJ project and a web project, and imported the java
code formatter and code templates setting. Nothing else.

If there is any difference, I have not injected the MyEclipse subscription
code yet.

What can I say!
