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

For recent versions of Android Studio, if changing just the Kotlin Target VM version didn't work.

File ➞ Project Structure ➞ Modules (app): set both "Source Compatibility" and "Target Compatibility" to "1.8 (Java 8)". Press "OK" and sync project with Gradle.
