I'm using Gradle wrapper 6.6, but I keep getting this error when compiling my Gradle Kotlin DSL buildSrc code. Why is it using a much older Gradle version for buildSrc? Or is the message bogus?

* What went wrong:
An exception occurred applying plugin request [id: 'org.jetbrains.kotlin.jvm', version: '1.4.0']
> Failed to apply plugin [id 'org.jetbrains.kotlin.jvm']
   > The current Gradle version 5.2.1 is not compatible with the Kotlin Gradle plugin. Please use Gradle 5.3 or newer, or the previous version of the Kotlin plugin.

are you sure your wrapper is updated? Looks like gradle on os is 6.6, but wraper is set to 5.3

[Big Chungus]

or the other way arround, depending on how you invoke the build

[colintheshots]

On the top-level project, I have this gradle-wrapper.properties distributionUrl. distributionUrl=https\:<//services.gradle.org/distributions/gradle-6.6-all.zip>

[Javier]

What command are you running?

[Big Chungus]

gradle build != gradlew build

[Javier]

try ./gradlew clean build

[colintheshots]

I know that. Android Studio is attempting to run some unit tests.

[colintheshots]

It's also clearly referencing Gradle 6.6 if I do ./gradlew clean build...

[Big Chungus]

Ah, i see

[Big Chungus]

Try tweaking your settings to this to make sure android studio is using wrapper too

[colintheshots]

Looks like it is.

[colintheshots]

I'm only having this issue inside the buildSrc folder of one module.

[Big Chungus]

Oooh, right

[Big Chungus]

that's a different story

[Big Chungus]

you cannot use kotlin 1.4 for buildSrc as it needs to match kotlin used by gradle distro (latest currently is 1.3.72)

[colintheshots]

Thank you! That makes sense. Ok. I downgraded to 1.3.72 and now it's saying in a series of errors that I need a dependency on stdlib. I do though.

[colintheshots]

This is what I have in my buildSrc build.gradle.kts file:

plugins {
    kotlin("jvm") version "1.3.72"
}

repositories {
    jcenter()
}

[colintheshots]

The module build.gradle.kts includes stdlib-jdk8 under dependencies.

[Big Chungus]

buildSrc does not share main module's dependencies

[Big Chungus]

so you need to declare it again explicitly

[colintheshots]

Oh, that must be it.

[Javier]

plugins {
    `kotlin-dsl`
}

repositories {
    jcenter()
}

[Big Chungus]

@Javier what does kotlin-dsl plugin do exactly? Seen it in many places, but don' have a clue what it's used for

[Javier]

https://docs.gradle.org/current/userguide/kotlin_dsl.html

[Big Chungus]

yes, but why do you need a plugin?

[Big Chungus]

or does it manage the koltin dependencies for ou automatically?

[Javier]

You need it to use Kotlin inside buildSrc and generate accessors
