Writing an annotation processor for maven-processor-plugin

Question

I am interested in writing an annotation processor for the maven-processor-plugin. I am relatively new to Maven.

Where in the project path should the processor Java

Answer 1

The easiest way is to keep your annotation processor in a separate project that you include as dependency.

If that doesn't work for you, use this config

Compiler Plugin:

    org.apache.maven.plugins
    maven-compiler-plugin
    2.3.2
    
        1.5
        1.5
    
    true
    
        
            default-compile
            true
            
                
                path/to/processor
            
        
        
            after-processing
            process-classes
            
                compile
            
            false
            
                path/to/processor
            
        
    

Processor Plugin:

    org.bsc.maven
    maven-processor-plugin
    
        
            process
            
                process
            
            compile
            
                
                    com.yourcompany.YourProcessor
                
            
        
    

(Note that this must be executed between the two compile runs, so it is essential that you place this code in the pom.xml after the above maven-compiler-plugin configuration)

Jar Plugin:

    org.apache.maven.plugins
    maven-jar-plugin
    2.3.1
    
        path/to/processor
    
    true
