Programming makes everything

Trouble Shooting history When I create spring-boot with Kotlin, IntelliJ can't reconize Kotlin class. As a result, I added the standard library to dependency management. implementation("org.jetbrains.kotlin:kotlin-stdlib")Kotlin-stdlib has extended versions of the standard library that add support for some of the features of JDK 7 and JDK 8. Checking https://kotlinlang.org/docs/reference/usi..

I create new project with IntelliJ's spring initializer (link : https://start.spring.io/ ) And main function is automatically generate, but runApplication does not configured because below can't import. import org.springframework.boot.runApplication As a result, I upgrade spring boot version from 1.x.x to 2.0.4.RELEASE and problem resolved.
