Answer 1

It is not actually possible to load properties from a file using the instructions in the accepted answer as these properties are not available in the pom file though they can be used for filtering. Minimal counter example:

In pom.xml:

  
    
      org.codehaus.mojo
      properties-maven-plugin
      1.0-alpha-2
      
        
        
          
          validate
          
            read-project-properties
          
          
            
              dev.properties
            
          
        
      
    
    
      org.apache.maven.plugins
      maven-antrun-plugin
      1.6
      
        
          validate
          
            run
          
          
            
              Displaying value of properties
              [foo] ${foo}
            
          
        
      
    
  

Having in dev.properties:

foo=bar

Then runnin the command mvn validate produces output:

 [echo] Displaying value of properties
 [echo] [foo] bar
