In the Xbase and Xtend doc it is not mentioned that the return type must be named and a colon is required.

def create new Person() copy(Person p) {
    name = p.name
    // now it works    
    friendWith = p.friendWith.map( p | p.copy )   
    marriedWith = p.marriedWith.map( p | p.copy ) 
} 


=>

def create target : new Person() copy(Person p) {
    target.name = p.name
    // now it works    
    target.friendWith = p.friendWith.map( p | p.copy )   
    target.marriedWith = p.marriedWith.map( p | p.copy ) 
}
