[Android] CompilationErrorException 오류

 

프로젝트 작업 중 기능 구현을 하고 프로그램을 실행시켰더니 갑자기 오류가 발생했다

 

app:compileDebugKotlin

org.jetbrains.kotlin.gradle.tasks.CompilationErrorException : Compilation error

 

와 같은 에러가 났다고  표시됐고 빌드 오류라 로그캣도 이용할 수 없었다.

오류 났다고 표시된 MainActivity.kt의 15번째 줄도 import 문이었기 때문에 발생 이유를 찾기가 힘들었다.

 

 

구글링 해도 별 다른 해결책을 찾지 못하던 때

A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

 

스택오버플로 페이지에서 터미널을 이용해 더 자세한 오류 내용을 볼 수 있다는 내용을 발견했다!

 

./gradlew assembleDebug --stacktrace

 

안드로이드 스튜디오 터미널에서 위 명령어를 실행했더니 아래와 같은 오류 메시지가 나왔다..!

정확하게는 모르겠지만 계속 build.gradle 8.0.2 library 라는 말이 반복적으로 나오는 걸 보니 

빌드 파일에 문제가 생겼나 싶었다.

[해결방법] compileDebugKotlin Exception 간단하게 해결하기

 

위 링크에서 코틀린 버전을 변경하라고 해서

 

id 'org.jetbrains.kotlin.android' version '1.8.20' apply false

 

이 코드를 아래와 같이 변경해 sync 해줬더니

id 'org.jetbrains.kotlin.android' version '1.9.0' apply false

 

 

성공적으로 빌드되어 실행되었다!!!!

 

 

 

안드로이드 스튜디오 내에서 오류에 대한 정보가 너무 안나와서 해결하는 데 오래걸렸지만

그래도 터미널 명령어를 사용해서 오류 내용을 더 자세히 보는 방법을 알게되었다!
