Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6
I can't find a solution on IDEA, but it's ok on Android Studio, and IDEA using the same JDK 1.8 from Android Studio

You should ask on #C5UPMM0A0, that is related to their library. Are you sure you are executing it exactly the same way in IDEA & AS? It looks like IDEA has a Kotlin target set for 1.6

@CLOVIS where I can change this target set in IDEA? I look at the project setting and settings they're both 1.8

What build tool are you using?

@CLOVIS thanks for reply, find out it's another package's problem :)
