Is there a way to only have kotlin_version defined in one place when using gradle kts and buildSrc? I’ve tried having an object inside of buildSrc, but I can’t reference that in buildSrc’s build.gradle.kts plugin block itself. I’ve tried putting it into gradle.properties and reading it out, which requried a workaround I found on github, but then didn’t work outside of the buildSrc module. This seems like something there should be a good accepted solution for

I'm using embeddedKotlinVersion
https://gradle.github.io/kotlin-dsl-docs/api/org.gradle.kotlin.dsl/embedded-kotlin-version.html

[zachtib]

so, that’s just for the build itself, right? ie, my app can still use 1.3.50?

[Thiago Nerys]

That version comes from gradle-kotlin-dsl plugin. Mine is pretty recent (1.3.41), but yes, that's the Kotlin version you use in your project.

[zachtib]

I’ll look into it, thanks

[Thiago Nerys]

One workaround would be define val kotlinVersion = "1.3.50" and add that to ext, then you can use the variable in your buildscript and the ext in the other modules.

I feel like I’ve tried that and it still bails in the plugin block

[Thiago Nerys]

That's right... Let me take a look.

The Kotlin DSL does not yet support replacement of properties in the version argument.

This is the best I was able to come with

[zachtib]

Interesting. That’s what I’d tried to do, but couldn’t get access to the Versions object within the plugins { } block at runtime

[Thiago Nerys]

Did you add the build.gradle.kts to buildSrc root?

plugins {
    `kotlin-dsl`
}

repositories {
    mavenCentral()
}

[zachtib]

yeah, that was the plugin block that was having problems

[Thiago Nerys]

Can't think of anything but gradle version then

[Thiago Nerys]

It is compiling here.

well ok, now it’s working. I took the kotlin("jvm") plugin out from `buildSrc`’s build.gradle.kts file and now things are working
