Maven compilation fails with @Delegate #412

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.  Sample project attached

What is the expected output? What do you see instead?
Build succeeds in Eclipse, but fails in Maven.

It appears that some methods are not @delegated correctly for some reason.

The class in question is:

public class MedaiAppender implements IMediaWriter {

    @Delegate
    private final IMediaWriter writer;

    public MedaiAppender(IMediaWriter writer)
    {
        this.writer = writer;
    }   
}

generates:
com.mangofactory.sample.MedaiAppender is not abstract and does not override 
abstract method getListeners() in com.xuggle.mediatool.IMediaGenerator

The inheritence chain to IMediaGenerator is:
IMedaWriter -> IMediaTool -> IMediaGenerator

I'm unsure of what is 'special' about IMediaGenerator.  I've tried with a 
similar inheritence chain in the attached project, and it works fine.

What version of the product are you using? On what operating system?
Tried against 0.11.4 and 0.10.8

test case starts downloading commons-cli.jar from an svn repo on googlecode. 
About 45MB into the download, I decided to abort this test case. Can you make 
it simpler?

Maven. Downloading half the internet since 1998.

New maven rule: Maven test cases are only accepted if they can manage to stick 
to downloading less than 10% of the internet.

I have just run into the same problem and created a testcase that, hopefully, 
downloads only a few percent of the (by now considerably grown) Internet. It is 
doing the same as the example above, just with native java classes. The only 
dependency is lombok 0.11.8
The error appears from within eclipse juno,m2e, maven 3
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) Server VM (build 23.21-b01, mixed mode)
But also from command line with maven 2

maven output from eclipse:

Updated the demo/test class (removed further code). Now it is just this:

import java.util.concurrent.ScheduledExecutorService;
import lombok.Delegate;
public class ProtectedScheduledExecutorService implements 
ScheduledExecutorService {
    @Delegate
    private ScheduledExecutorService delegate;
}

Here is the verbose javac output from the command line that maven constructs at 
my system - just in case that helps find the problem without downloading the 
Internet, first.

I have the same issue, I am trying to install TinCan API and it has lombok as 
dependency. 
I have java 7, and maven 3. version required is 11.6.

I have the same issue even with 1.12.4. Using Java 1.7.0_45 and maven 3.0.5

In fact the compilation fails even within the IntelliJ IDEA IDE.

Same problem here... The last added testDelegate.tar.bz2 illustrates the 
problem clearly. It fails, but there is no reason to fail.
