我在 Spring Boot 项目中使用 H2 数据库。我在 build.gradle.kts 文件中有对 h2 的运行时依赖，但它无法找到驱动程序。

这就是我添加运行时依赖项的方式

runtimeOnly("com.h2database:h2")

这是插件配置

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"
}

我错过了什么吗？
