Annotation processor logger

A dedicated annotation processor SLF4J implementation which delegates logging to javax.annotation.processing.Messager.

Usage

1. Add the dependency to your annotation processor project

   <dependency>
     <groupId>com.cosium.logging</groupId>
     <artifactId>annotation-processor-logger</artifactId>
     <version>${annotation-processor-logger.version}</version>
   </dependency>

2. Make your javax.annotation.processing.Processor extend com.cosium.logging.annotation_processor.AbstractLoggingProcessor

   public class MyProcessor extends AbstractLoggingProcessor {
       protected boolean doProcess(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
           // Make the world a better place
       }
   }

3. Use SLF4J as usual

Enabling all logging levels

Maven

In the Maven project using your annotation processor, enable showWarnings in maven-compiler-plugin

<build>
  <plugins>
    <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-compiler-plugin</artifactId>
       <configuration>
         <showWarnings>true</showWarnings>
       </configuration>
    </plugin>
  </plugins>
</build>
