Hello, I’m having this error:

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option
Adding support for Java 8 language features could solve this issue.

And if I choose “fix it” the IDE adds this to my

build.gradle.kts

in shared module:

android {
   ...
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Thing is,

kotlinOptions

throws unresolved reference. How can I fix this? Thanks 🙏 ps: don’t know if it’s related or just a coincidence, but I got this error after adding multiplatformSettings lib 🤔

try this

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

perfect @John O'Reilly, thanks!

What AGP version do you have?

Using 4.2.1

Was it only failing to resolve in the IDE or did Gradle sync or any other Gradle run also failed?

gradle sync was ok, but building was throwing:

:shared:compileDebugKotlinAndroid
Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

one line per inline operation ^
