Updated from Kotlin 1.6.21 to 1.7.0, I get this

> Task :buildSrc:compileKotlin
'compileJava' task (current target is 11) and 'compileKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version.

Dependencies of my buildSrc subproject:

dependencies {
    compileOnly(gradleKotlinDsl())
    implementation("com.android.tools.build:gradle:$androidGradleVersion")
    implementation("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion")
    implementation("org.jetbrains.kotlin:kotlin-compiler-embeddable:$kotlinVersion")
}

What is happening?

[ephemient]

buildSrc and other things loaded into Gradle's classpath are always run with Gradle's embedded Kotlin

[ephemient]

https://docs.gradle.org/7.5-rc-2/userguide/compatibility.html#kotlin

[ribesg]

Does that mean I should have a version of Kotlin for my code and take the one from Gradle for the JB dependencies I use in my build files?

[ephemient]

not sure what you mean by that

[ephemient]

kotlin-gradle-plugin:1.7.0 works with Gradle's embedded Kotlin version, so you can update that fine

[ephemient]

kotlin-compiler-embeddable should not need to be in the buildscript classpath

[ribesg]

But not kotlin-compiler-embeddable?

[ephemient]

correct

[ribesg]

Maybe it’s dead code, let’s see if anything fails if I remove it

[ribesg]

Looks like it works. I no longer needed it. Thanks!

[nuhkoca]

sorry for the unrelated question but what is difference between those, you know?

compileOnly(gradleApi())
compileOnly(gradleKotlinDsl())
compileOnly(localGroovy())
