After updating to android build tools 4.2.0, I get a build failure when I remove this (I’ll update this with more detail when I get the chance)

kotlinOptions {
    jvmTarget = "1.8"
}

If I only remove this, then all builds fine:

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

Yes, because 1.8 is default now.

Not working for me. I don’t have the exact error right now. But it mentions an issue with unable to inline 1.8 with 1.6 (I Ithink)

[Thiago]

Humm, must be a bug so.
Java language version 8 by default

What Kotlin version are you using? I believe you need to be using Kotlin 1.5.0 to remove the jvmTarget = "1.8"

Thanks @Nicholas Doglio Yes, I haven’t updated Kotlin yet, because of a compiler bug that prevents some of my code compiling. So I’m holding off first until that is fixed.
