我使用Exposed作为我的数据库库,当我尝试运行我的代码时出现这些错误:

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")
}

我想我正确地遵循了示例代码,但我无法弄清楚是什么引发了这些。

您需要将kotlin-reflect依赖项添加到您的项目中。
