我有一个 KMM 项目并想使用SqlDelight库，但是当我构建项目时没有生成数据库模式和表实体。

actual class DatabaseDriverFactory(private val context: Context) {
    actual fun createDriver(): SqlDriver {
               //Unresolved reference: CoreDb
        return AndroidSqliteDriver(CoreDb.Schema, context, "test.db")
    }
}

我已经在我的共享模块中定义了 sqldelight 文件夹，并且还为功能生成的 kotlin 类创建了文件夹，因为它是在其中配置的，并且在文件夹中gradle.build.kts还有一个*.sq文件sqldelight

sqldelight {
  database("CoreDb") {
    packageName = "com.example.app.core.database"
    sourceFolders = listOf("sqldelight")
    dialect = "sqlite:3.24"
  }
}

当我运行generateSqlDelightInterface任务时，我只看到那些日志

> Task :core:generateAndroidDebugCoreDbInterface NO-SOURCE
> Task :core:generateAndroidReleaseCoreDbInterface NO-SOURCE
> Task :core:generateIosMainCoreDbInterface NO-SOURCE
> Task :core:generateMetadataCommonMainCoreDbInterface NO-SOURCE
> Task :core:generateMetadataMainCoreDbInterface NO-SOURCE
> Task :core:generateSqlDelightInterface UP-TO-DATE
can't register checkAndroidModules

这是我的完整build.gradle.kts

似乎您的sqldelight文件夹，您将*.sq文件放在错误的位置。

它应该直接放在里面commonMain，并且sqldelight您必须指定您的包裹。

其他可能的原因

正如 IgorGanapolsky 指出的那样，同样的问题也可能是由不兼容的 gradle 插件版本引起的。

这可能对将来的某人有所帮助...我在 KMM 中创建了一个目录，并将其命名为sqldelight.com.package.database

我认为这是一个合适的包，但意识到这并没有被 SQLDelight 捕获，因此没有生成我的模式。

我需要将结构创建为正确的目录结构（然后一切正常）：

sqldelight
  com
    package
      dataabase
