Gradle version 4.5.1

gradle.properties

kotlin.version=1.2.21

build.gradle.kts

settings.gradle.kts

rootProject.name = "blabla"

$ gradle tasks result:

Hmm, I thought that you cannot use gradle.rootProject in setting.gradle. Is this ever worked for you?

[Czar]

Yup, works for Gradle 4.4.1

[gildor]

But it doesn’t work for your case. Version of plugin is empty and cause this error

[Czar]

The same thing works with gradle 4.4.1 and does not work with gradle 4.5.1

[Czar]

I'll create demo and post it shortly

[gildor]

hmm

[Czar]

Weird, I tried to write a testkit demo project to showcase what's happening in a test, but with testkit both versions fail: 4.4.1 and 4.5.1

[Czar]

Also, useVersion("1.2.21") doesn't work either, so access to rootProject is not the problem.

[Czar]

Next thing I'll try: checking if the problem is the same with groovy gradle.settings. If it is, then it is not Kotlin related and I'll move to gradle issue tracker

[gildor]

groovy should also support this syntax in setting.gradle to access gradle properties settings["kotlin.version"]

[gildor]

you can try, maybe it’s gradle.properties problem

[Czar]

I'm totally weirded out now, I've created small demo project with source above and it doesn't work in 4.4.1 too... whilst I have a working project with exactly same configuration, which does work in 4.4.1. The working one is here: https://github.com/AlexCzar/db-info-demo

[Czar]

actually, db-info-demo works even with gradle 4.5.1

[Czar]

and it's not properties problem, as I've said, even when I use literal "1.2.21" instead of referencing properties, I get the same problem. I think settings file is not evaluated at all, because none of my println("something") that I place there to check are reached.

[Czar]

Shit... I wasn't naming some of the files correctly, in the ones which work name was correct: settings.gradle.kts, in ones which didn't work gradle.settings.kts. gradle versions were irrelevant I just had two projects one with 4.4.1 (and correct file name) and one with 4.5.1 (and incorrect file name)

[gildor]

🤣

[gildor]

cool bug!

[Czar]

I stumble upon this particular issue once or twice a year and I keep forgetting about it until the next time 😄 I hate that.

[Czar]

"gradle settings" sounds more natural to my ear, "gradle build" too for that matter, but I create "build.gradle" all the time and don't make the mistake, I create "settings.gradle" less often, so the mistake is always lurking in the shadows 😄
