Description

I am using the @Immutable annotation and need to customize the @EqualsAndHashCode fields. If the @Immutable annotation appears first it doesn't work. However, if I place @EqualsAndHashCode first it works.

@Canonical works correctly regardless of what order the annotations appear.

import groovy.transform.*

@EqualsAndHashCode(includes = ['id'])
@Immutable
class A {
    String id
    String name
}

@Immutable
@EqualsAndHashCode(includes = ['id'])
class B {
    String id
    String name
}

def a1 = new A('1', 'foo')
def a2 = new A('1', 'foo2')

assert a1.equals(a2)
assert a2.equals(a1)

def b1 = new B('1', 'foo')
def b2 = new B('1', 'foo2')

assert b1.equals(b2)  // fails
assert b2.equals(b1)  // fails
