Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6

Question

When trying to run the Example CorDapp (GitHub CorDapp) via IntelliJ, I receive the following error:

Cannot inline bytecode built with JVM target 1.8 int

Answer 1

In my case, jvmTarget was already set in build.gradle file as below.

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

But my issue was still there. Finally, it gets resolved after Changing Target JVM version from 1.6 to 1.8 in Preferences > Other Settings > Kotlin Compiler > Target JVM version. see attached picture,
