can maven compile multiple source folder to multiple target folder

I am trying to change a ant project to maven project, here is the problem. for example: I have two source folder.

-pom.xml    
-ejb
    -org
        -x
          -ejbclass1.java
-tpf
    -org
        -x
          -tpfclass1.java

now I want to generate class file under target folder like this:

ejb
   -classes
           -org
               -x
                 -ejbclass1.class
tpf
   -classes
           -org
               -x
                 -tpfclass1.class

is there any plugin can do this?

Create two seperate maven prosjectst and bind them with one super project (maven projects can be chierarchical).

Your directory structure chould look like this:

master-pom.pom
  ejb {dir}
     ejb-pom.pom
     src {dir} 
     ....
  tpf {dir}
     tpf-pom.pom
     src {dir} 
     ...

use <modules> tag in master pom.

Compiling a master procject will compile both subprojects

here's a tutorial
