IntelliJ 에서 Kotlin 프로젝트 실행시 오류 모음

1. 찾아보면 IntelliJ에서만 나타난다고 한다..

에러

Error running 'Application': Command line is too long.
Shorten command line for Application or also for Spring Boot default configuration. 

 

1-1. 위 빨간색 에러에서 파란색 부분을 눌러서 진입한다.

1-2. 저걸 놓쳤다면 실행시키면 생기는 프로젝트 Run 되고 있는거 확인 할 수 있는 곳?(메뉴에서 들어가는건 찾지 못했다.) 에서

Edit Configurations 를 눌러서 진입한다.

2. run할 프로젝트를 선택 후

Shorten command line 을

classpath file 로 선택해준다.

apply

그럼 잘 실행된다.

 

2. driverclassname error

본론만 말하자면 properties 파일에서 무엇인가 문제가 있었던 것이다.

properties를 좀 더 잘 보자 오타.. 안습..
