[project lombok] Custom annotations with Lombok

[daver]

I was following this thread with great interest (from Franz):

http://groups.google.com/group/project-lombok/browse_thread/thread/3e47f43aec82a855

I took his code (thanks Franz for posting it...) and put it into a
test project, but I'm unable to get the helloField to show in my
code...I have the Eclipse and Javac implementations both compiling--
easy enough. When I copied the code, I did move them to separate
packages (for organization):

com.mypackage.annotation.Hello
com.mypackage.annotation.handler.HandleHello
com.mypackage.annotation.handler.eclipse.HandleHello

By doing this, did I hose something? I can't see how these hook into
Lombok as extensions. Do I have to build a custom lombok.jar to make
that happen? Or something else? Or both?

I'm digging to find something to start from here...Suggestions?

Thanks,
-Dave

Good day,

I'd just like to correct my HandleHello.java for eclipse: The line with 'injectMethod(fieldNode, method);' should have been 'injectMethod(fieldNode.up(), method);' With that change, @HandleHello should now work properly in your eclipse.

What I did was I modified lombok's sources themselves. That's where I added @Hello and eclipse & javac HandleHello java files. 

( But do check if you can see your handlers in build/lombok/META-INF/services/lombok.eclipse.EclipseAnnotationHandler and in build/lombok/META-INF/services/lombok.javac.JavacAnnotationHandler ). 

I am not sure though if it would be possible to create a separate jar (i.e. lombok-hello-ext.jar) and have lombok pick that up at runtime. Maybe you can create your own lombok.eclipse.EclipseAnnotationHandler & lombok.javac.JavacAnnotationHandler files inside your new jar? ...I'm not sure. I haven't tested that yet.

Also, in case you're interested on how I used this new lombok annotation, I'm attaching the sample project that I used to test my @Hello (Note: this is a maven project).

Steps to test:

1.) Build lombok (with the @Hello and HandleHello java files).

2.) Install dist/lombok jar in your local repository (mvn install:install-file -DgroupId=org.projectlombok -DartifactId=lombok -Dversion=0.9.3-EDGE -Dpackaging=jar -Dfile=dist/lombok.jar)

3.) Untar lombok-sample.tar.gz

To test Javac HandleHello:

4.) Go to the directory where you exploded lombok-sample.tar.gz

5.) Run mvn clean test

* If @Hello worked, then you should see a Build Successful. If not, then you will see a compile error.

To test Eclipse HandleHello:

4.) Run the newly created dist/lombok.jar (and install this lombok to your eclipse)

5.) Run eclipse and import the exploded lombok-sample to your eclipse as an eclipse project

6.) Run AppTest

* If @Hello worked, then the tests should pass. If not, then you will most probably get an Eclipse error or a compile error.

Cheers

You should be able to have your own jar file that contains the META-
INF/services/lombok.eclipse.EclipseAnnotationHandler and META-INF/
services/lombok.javac.JavacAnnotationHandler files containing just one
line: the fully qualified class name of the handler. Lombok uses the
Service Provider Interface API to discover the handlers on the
classpath.

Thanks guys. I got mine working after getting the lombok project
compiling and shoe-horning it inside there. I'll break it out based
on the suggestions above.
