This is how I added the runtime dependency
runtimeOnly("com.h2database:h2")
and this is plugin configuration
plugins {
id("org.springframework.boot") version "2.2.5.RELEASE"
id("io.spring.dependency-management") version "1.0.9.RELEASE"
kotlin("jvm") version "1.3.61"
kotlin("plugin.spring") version "1.3.61"
}
Am I missing something ?
