"build path incomplete" error

**memelet** · Jul 9th, 2007, 06:23 PM

I am getting this error for /every/ bean in my config file. I can ctrl-cliick the classes and open the file. I can run the program correctly. The classes are indeed in the build path.

Once I get these errors the only way I have found to get rid of them is to physically move the config file out the project, refresh, then bring the file back in. However, this only works for a bit. As soon as spring-ide has any issues (eg, I use a tag that spring-ide does not know) I get the errors again.

I am using eclipse 3.3 the very latest spring-ide 2.0.

I do get a lot of plugin errors, below are two. I'm wondering if there is some type of compatibly issues with ecipse 3.3?

Wait, I think I found the trigger. Adding/removing "aop:aspectj-autoproxy" adds/removes the build path errors.

**Christian Dupuis** · Jul 10th, 2007, 02:06 AM

Hi,

the stacktraces you posted have are not linked with the build path incomplete problem. What version of Spring IDE are you using? This is quite interesting as this error has been addressed pre 2.0 final.

What is exactly the error message you get as incomplete build path? You should a get a name of a missing class.

Code:

Build path is incomplete. Cannot find class file for {0}

Please note that Spring IDE or the nested AspectJ rt needs all classes to which your class has a binary dependency on the Eclipse Project classpath. Quite helpful could be the output of the Spring AOP Event Trace View.

**memelet** · Jul 10th, 2007, 06:29 AM

Good morning (from here) Christian,

I'll gather up the AOP trace info shortly.

As for the build path message, it is indeed of the format you showed. But the messages for are /every/ bean class="..", without exception. So I think the problem is more general. And if I remove the aop:aspect-autoproxy and save the config file all the error messages are cleared. It seems as if something is getting confused, not that there is really any missing classes or build path problem.

Having said the above, as I was typing this, I used my running eclipse from when I posted last night, added the aop:aspectj-autoproxy to get the trace info, and, uhm, no errors. I am stymied.

I am using the very latest spring-ide, which I updated yesterday. Let me track a bit more before I bother you anymore. Maybe it had something to do with eclipse not fully updating/refreshing the plugin cache or some such.

thanks!!

**Christian Dupuis** · Jul 10th, 2007, 06:40 AM

Hi Barry,

looking forward to get some more info about the problem. I want to make sure that we tackle this issue down.

Christian

**memelet** · Jul 10th, 2007, 07:59 AM

Ok, the reason I no longer get the error is because I had remove the spring nature.

Below is the event trace (truncated due to forum limits). The missing classes are for /every/ bean class="..".

The spring-ide version is 2.0.0.v200706271108

Hmm, that seems to be related to the class:

Code:

org/springframework/ws/soap/server/endpoint/SoapFaultDefinition

Where is this referenced in your code? Can you show me the FaultExceptionMessageResolverAspect (only signatures and @Aspect annotations are enough).

Thanks

Christian

**memelet** · Jul 10th, 2007, 09:38 AM

Below is the aspect.

At runtime I am getting this error, surely this must have something do with the problem

Code:

        SoapFaultDefinition faultDefinition = (SoapFaultDefinition)pjp.proceed();

        return faultDefinition;
    }

        if (faultDefinition != null) {
            if (faultDefinition.getFaultStringOrReason().equals(EX_MESSAGE_KEY)) {
                faultDefinition.setFaultStringOrReason(ex.getMessage());
            }
        }
    }
}

**memelet** · Jul 10th, 2007, 10:01 AM

Well I removed all references to SoapFaultDefinition from the aspect (changed the around advice to return Object). That got rid of those errors, but now I get the same for other classes.

So it seams that the problem is not with a specific class, but that the classpath spring-ide is using somehow gets corrupted.

**Christian Dupuis** · Jul 10th, 2007, 10:27 AM

I'll look into this. I think I have some really good information now to reproduce it (hopefully).

Just for curiosity: Is the project your are working an Aspect enabled one (having the AJDT nature)?
