Message from my annotation processor don't appear in console

Hi,

Recently I was writing an annotation processor [1]  which gets called 
from javac. JDK 6 javac exposes an API called Messager to be used to 
report warnings or errors or diagnostic information. I noticed that if I 
launch javac from command line, my messages appear in the output, but 
when javac is invcoked by maven-compiler-plugin, my messages don't 
appear. While debugging I found that maven passes StringWriter to javac 
to write the messages to and javac is also writing to that object, so I 
suspect maven is not subsequently printing the information available in 
the StringWriter object. More information is available at [2].

Thanks,
Sahoo

Hi,

I do not have an answer to your question, sorry. But I wonder if you can
help me with a small problem i have?

Im trying to invoke the annotation processor from Maven, and i cannot get
Maven to invoke my processors during 'compile'..

It works fine with straight javac...

I have configured maven-compiler-plugin like so:

           <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-compiler-plugin</artifactId>
               <version>2.0</version>
               <configuration>
                   <source>1.6</source>
                   <target>1.6</target>
                   <encoding>utf-8</encoding>
                   <compilerArgument>-proc:only</compilerArgument>
               </configuration>
           </plugin>

Is there anything more that i have to do trigger my processor?

thanks,
-Kristoffer
