(mentioned in the Google Groups a few times but doesn't seem to be in the issues list)

plain Java:

class Foo {
private int x;
private String s;

public Foo setX(int x) { this.x = x; }
public Foo setS(String s) { this.s = s; }
}

use case:

Foo foo = new Foo().setX(3).setS("something");

If this is part of the @ Builder implementation (issue #89), and the fluent setters are easier to implement than the @ Builder, please release this one first.

(this should have been an enhancement, not a defect, sorry)

Darn -- I just noticed issue #88. This is a duplicate.

But again, if it's easier to implement than the full @ Builder, please release this first.

Please reopen.

There is a difference between Builder and Fluent; please add a @ Fluent along the lines of this:

http://martinfowler.com/bliki/FluentInterface.html

The main problem with builder is the build() method. I just want to make a @ Data class with chainable set() methods, not a Builder. The reason for this is that the Data class gets passed up several levels and is manipulated along the way. I'd rather not pass a builder but instead a DTO with fluent setters.

@ Accessors(fluent=true) should do the trick for you.
