How to copy a resource or another in Maven depending on the target environment?

Question

I have to create test war and production war, which will have a different log4j.properties file in the WEB-INF directory. I have these files

Answer 1

The alternative way is to use maven-antrun-plugin

    
        
          org.apache.maven.plugins
          maven-antrun-plugin
          1.7
          
            
              validate
              
                run
              
              
                
                  build.env: ${build.env} 
                  
                  
                
              
            
          
        
    

Assume resource files are in following structure:

src/
  env/
      dev/
          log4j.properties
      local/
          log4j.properties
      prod/
          log4j.properties

When do maven build, run the following commands per environment:

mvn package -Dbuild.env=dev
mvn package -Dbuild.env=local
mvn package -Dbuild.env=prod
