未生成 Sqldelight 数据库架构

Question

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架构和表实体。

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

我在我的共享模块中定义了 sqldelight 文件夹，还为功能生成的 kotlin 类创建了文件夹，因为它在 gradle.build.kts 中配置，并且在 sqldelight 文件夹中还有一个 *.sq 文件

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

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

> 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

BUILD SUCCESSFUL in 311ms

这是我完整的build.gradle.kts

  core //(kmm shared module)
    androidMain
        com.example.app.core
            database

            sqldelight
    iosMain
        com.example.app.core
            database

Answer 1

您的 sqldelight 文件夹似乎放错了位置。

应该直接放在commonMain里面，sqldelight里面你必须指定你的包。

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。

Answer 2

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，因此没有生成我的架构。

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

Answer 3

或者，如果您希望 SQL 代码与您的代码位于同一目录中，您可以将文件夹更改为 kotlin：

sqldelight {
  database("CoreDb") {
    ...
    sourceFolders = listOf("kotlin")
    ...
  }
}
