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"
    }
}

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

[Guilherme Delgado]

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 ^
