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

that is being built with jvm target 1.6. please specify proper '-jvm-target' option 에러가 뜬다면!!

 

 

File-settings안의 kotlin compiler 안의 target JVM version을 바꿔준다 

 

 

 

바꿔줘도 에러가 뜬다면 

File-Invalidate Caches / Restart 후 Build - Clean Project 

 

이래도 안되면 

build.gradle(module:app)안의 

android{} 안에 kotlinOptions{jvmTarget = "1.8"} 을 넣는다
