的NoClassDefFoundError当使用裸露

Question

我用Exposed作为我的数据库库，当我尝试运行我的代码我得到这些错误：

Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/reflect/full/KClasses

代码片段SQLObjects.kt：

object Songs : Table() { 
    val _id = integer("_id").autoIncrement().primaryKey() // Line 14 
    val songId = integer("song_id") 
    val title = text("title") 
    val artist = text("artist") 
    val levelBSC = integer("level_bsc") 
    val levelADV = integer("level_adv") 
    val levelEXT = integer("level_ext") 
} 

我认为我遵循了示例代码，但我无法弄清楚是什么抛出了这些。

您需要将kotlin-reflect作为依赖项添加到您的项目中。
