android-studio - 找不到参数的方法 ksp()

Question

我刚开始学习 Kotlin 中的 Android，我正在创建一个笔记应用程序，只是为了学习目的。我想使用 Room 将保存的笔记存储在我的数据库中，所以我查看了 developer.android 教程并且我们有一些必要的依赖项，我们必须将其添加到我们的 build.gradle(Module) 中，如 developer.android.com 上所述https://developer.android.com/training/data-storage/room#kts但是当我添加这些依赖项时，我遇到了一个我无法弄清楚的错误

Could not find method ksp() for arguments [androidx.room:room-compiler:2.4.3] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler

我在使用 kapt 时遇到了类似的错误，但我通过在我的 build.gradle(Module) 中添加必要的插件解决了这个问题。现在我正在从我的 build.gradle 中删除这个实现并继续进行测试项目，但任何帮助将不胜感激，谢谢。

developer.android.com 中提到的依赖

dependencies {
    val room_version = "2.4.3"

    implementation("androidx.room:room-runtime:$room_version")
    annotationProcessor("androidx.room:room-compiler:$room_version")

    // To use Kotlin annotation processing tool (kapt)
    kapt("androidx.room:room-compiler:$room_version")
    // To use Kotlin Symbol Processing (KSP)
    ksp("androidx.room:room-compiler:$room_version")

    // optional - Kotlin Extensions and Coroutines support for Room
    implementation("androidx.room:room-ktx:$room_version")

    // optional - RxJava2 support for Room
    implementation("androidx.room:room-rxjava2:$room_version")

    // optional - RxJava3 support for Room
    implementation("androidx.room:room-rxjava3:$room_version")

    // optional - Guava support for Room, including Optional and ListenableFuture
    implementation("androidx.room:room-guava:$room_version")

    // optional - Test helpers
    testImplementation("androidx.room:room-testing:$room_version")

    // optional - Paging 3 Integration
    implementation("androidx.room:room-paging:$room_version")
}

我的build.gradle(模块)

我的build.gradle(项目)

    id 'com.android.library' version '7.3.1' apply false
    id 'org.jetbrains.kotlin.android' version '1.7.20' apply false
}

Answer 1

确保你的kotlin gradle插件版本是1.8.0:

classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.8.0'

在app级gradle文件中添加devependency

id 'com.google.devtools.ksp' 版本 '1.8.0-1.0.8'

最后，构建您的项目。
