[aspectj-users] Problem dusting off old AspectJ project: abstract aspect

[Matthew Adams <matthew@xxxxxxxxxxxxxxx>]

Hi all,

I'm blowing the dust off of an old AspectJ-based project I had been
working on, and I'm getting an error that I can't quite figure out.  I
have an abstract aspect that is introducing two Date fields.  Various
subaspects (4 of them) are attempting to access the field, but the
compiler is saying that the field is not visible.  I've included
relevant info below.  Anyone have an idea why this wouldn't work?  I'm
using Maven 2.2.1, JDK 1.6.0_25, and trying to use AspectJ 1.6.11 &
aspectj-maven-plugin 1.3.1.

...

The field AbstractPersistentlyAuditableMixin.IntroducedPersistentlyAuditable.datetimeUpdated
is not visible.


Here's the abstract aspect:


public abstract aspect AbstractPersistentlyAuditableMixin {

    public interface IntroducedPersistentlyAuditable extends
            PersistentlyAuditable {
    }

    @Column(name = "datetimePersisted")
    private Date
AbstractPersistentlyAuditableMixin.IntroducedPersistentlyAuditable.datetimePersisted;

    @Column(name = "datetimeUpdated")
    private Date
AbstractPersistentlyAuditableMixin.IntroducedPersistentlyAuditable.datetimeUpdated;

    public Date
AbstractPersistentlyAuditableMixin.IntroducedPersistentlyAuditable.getDatetimePersisted()
{
        return new Date(datetimePersisted.getTime());
    }

    public Date
AbstractPersistentlyAuditableMixin.IntroducedPersistentlyAuditable.getDatetimeUpdated()
{
        return new Date(datetimeUpdated.getTime());
    }
}


Here's one of the subaspects:


public aspect PersistentlyAuditableAdvisingPrePersistMixin extends
AbstractPersistentlyAuditableMixin {

    declare parents : ((@Entity *) && hasmethod(@PrePersist * *(..)))
implements IntroducedPersistentlyAuditable;

    after() returning : execution(@PrePersist * *(..)) {
	    datetimePersisted = new Date();
        datetimeUpdated = new Date();
    }
}

I'm using maven 2.2.1 with the aspectj-maven-plugin 1.3.1.  Here are
