What steps will reproduce the problem?

1. annotate Class with @ Data(staticConstructor = "of")
2. no Cstatic Constructor generated named of()
3. verify with delombok on the anotated class

What is the expected output? What do you see instead?
Constructor should be created like mentioned in doc

What version of the product are you using? On what operating system?
0.11.2

Please provide any additional information below.

Cannot reproduce. This simple testcase:

@ lombok.Data(staticConstructor="of")
public class Test {
private final String test;
}

run through java -jar lombok.jar delombok -p Test.java

shows that the static constructor IS showing up. Presumably there's something strange happening with your source code. Can you attach it in a comment?

deadline before marking as invalid: July 21st, 2012.

my beans are defined in this way:

import lombok.Data;
import lombok.NoArgsConstructor;

import javax.annotation.Nonnull;

@ Data(staticConstructor = "of")
@ NoArgsConstructor(access = AccessLevel.PROTECTED)
public class test {
@ Nonnull
private Integer test;
}

Could be related to issue #469

Not related to issue #469.

The problem is simple: When an explicit constructor annotation is present (i.e. @ NoArgsConstructor), @ Data just offloads all responsibilities to that parameter. Your code is buggy: You should use:

@ Data
@ NoArgsConstructor(staticName="of")

instead of:

@ Data(staticConstructor="of")
@ NoArgsConstructor

Note that your confusion is entirely justified, as lombok silently ignores you. We've added a feature to @ Data that it will warn you that your 'staticConstructor' is going to do absolutely nothing in this scenario.

This will be in 0.11.4, which will be released soon.
