A modern programming language that makes developers happier.

kotlinlang

Gradle version `4.5.1`

*gradle.properties* ```kotlin.version=1.2.21```
*build.gradle.kts* ```plugins {
	kotlin("jvm")
}```
*settings.gradle.kts* ```pluginManagement {
	repositories {
		gradlePluginPortal()
	}
	resolutionStrategy {
		eachPlugin {
			if (requested.id.id.startsWith("org.jetbrains.kotlin")) {
				useVersion(gradle.rootProject.extra["kotlin.version"] as String)
			}
		}
	}
}

rootProject.name = "blabla"```
`$ gradle tasks` result:
```FAILURE: Build failed with an exception.
Build file '/home/czar/work/occ/build.gradle.kts' line: 2
Plugin [id: 'org.jetbrains.kotlin.jvm'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Gradle Central Plugin Repository (plugin dependency must include a version number for this source)
```

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

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

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

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

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

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

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

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

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>

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

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.

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)

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

"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 :smile:
