RE: [jdt-apt-dev] Debugging Annotation Processors in Eclipse
|
Manish, this is working fine for me. Here's what I
did:
1. Unzipped your zip file into a workspace
d:\temp\manish. Started Eclipse (with APT plugin installed), loaded that
workspace, and imported and built the project.
By the way, I notice that you have apt enabled in that
project. I don't know why, since you don't have any annotations to be
processed in that project.
2. Put a breakpoint on
DemoAnnotationProcessor.process(). Launched the project in the debugger,
using "Debug As -> Eclipse Application", with the default workspace
(d:\temp\runtime-EclipseApplication).
3. In the second Eclipse instance (the instance being
debugged, that is, the one whose workspace is
d:\temp\runtime-EclipseApplication), created a new Java project named Foo.
Enabled apt for Foo, and added annotations.jar to the Java build path for
Foo.
4. In project Foo, created a new Java class named
Bar. In Bar, added a method named bar() and annotated it with
@DemoAnnotation.
Immediately, the breakpoint on
DemoAnnotationProcessor.process() is hit, in the first Eclipse instance
(d:\temp\manish).
If this is not working for you, can you send us a copy of
the project containing the annotated code you're trying to process? Are
you sure that you have apt enabled on that project?
Thanks,

Hi guys, I have been trying to debug annotation processor but no
luck yet. On the web site it
says... "
| To debug an annotation processor
it must be run from a plugin. You develop your code in the plugin, and
then debug it by annotating source code in a spawned instance of Eclipse.
The debugging instance needs the annotation declaration, the factory, and
the processor. The spawned instance only needs access to the delaration.
|
"
I created a plugin based on the APTDemo.
The processor code is in the plugin source folder along with a jar
dependency where annotations (@TypeGeneratingAnnotation and @DemoAnnotation) are
defined. Annotating the src code within a java project (which has the
annotations.jar in classpath) )in a spawned instance of Eclipse does not invoke
the processor (the break points do not get called). I am not sure what an I missing here but any help is
appreciated. The plugin zip file in my workspace is attached along with a pic
below.
