Stephen Albrecht updated GROOVY-11761:
--------------------------------------
Description:
I found this issue in GrooCSS, an older library for writing CSS in Groovy with
a DSL. It depends on Groovy 2.5.8 but using it with newer versions worked until
5.0.1.
Possibly related to GROOVY-10800
example build.gradle dependencies
{code:java}
dependencies {
implementation 'org.apache.groovy:groovy:4.0.28'
implementation 'org.groocss:groocss:1.0-GA'
}{code}
This simple program outputs some CSS.
{code:java}
package org.example
import org.groocss.GrooCSS
import org.groocss.Selector
static void main(String[] args) {
println GrooCSS.process {
keyframes('fadeOutBackground') {
0 % { backgroundColor blue }
}
a.foo {
color red
}
Selector s = a % link
s.foo {
extend(a.foo)
}
}.toString()
} {code}
Output (Groovy 4.0.28)
{code:java}
a.foo,a:link.foo {
color: Red;
}
@keyframes fadeOutBackground {
0% {
background-color: Blue;
}
}@-webkit-keyframes fadeOutBackground {
0% {
background-color: Blue;
}
}{code}
Updating to Groovy 5.0.1 breaks at runtime on the mod overload for keyframes

If you comment out the keyframes call, the result of `a % link` now returns
null when it used to return a Selector object. That mod method is defined
