Maven profile for single module

Question

I have a multi module maven project, which builds successfully, I\'d like to build just one of the modules I have. How would I do that with profiles ? I could d

Answer 1

To implement this with profiles, you could use two profiles, one with all modules and another one with the wanted module only. Something like this:

  
    all
    
      true
    
    
      module-1
      ...
      module-n
    
  
  
    module-2
    
      module-2
    
  

And then call it like this:

mvn -Pmodule-2 package

Two things to note here:

1. You need to move the from the POM in a "default" profile (because from a profile are only additive, they do not hide the modules declared in the POM).
2. By marking it as , the "default" profile will be picked if nothing else is active but deactivated if something else is.

One could even parametrize the name of the module and pass it as property:

  ...
  
    module-x
    
      
        module-name
      
    
    
      ${module-name}
    
  

And invoke maven like this:

mvn -Dmodule-name=module-2 package

But this is a poor implementation IMHO, I prefer the -pl "advanced" reactor options (less xml, much more power and flexibility):

mvn -pl module-2 package
