> Testing code:

>     final Settings s = new Settings();
>     s.setLocalRepository("xxx");
>     assertEquals("xxx", s.getLocalRepository()); // OK
>     s.setLocalRepository("yyy");
>     assertEquals("yyy", s.getLocalRepository()); // OK
>     s.setLocalRepository(null);
>     assertNull(s.getLocalRepository()); // FAIL{noformat}

> It seems related to the the build() method of Model Builder with forceCopy = false :
>  
> {noformat}
> ${field.name} != null ? ${field.name} : ( base != null ? base.${field.name} : null )${sep}
