Android Kotlin 项目中 Dagger Hilt 和 KSP 的问题：无法解析符号“Inject”

Question

我\xe2\x80\x99m 使用 Kotlin 处理 Android 项目，并使用 Dagger Hilt 进行依赖注入。最近，我\xe2\x80\x99ve尝试从kapt迁移到KSP（Kotlin符号处理）来生成代码，因为kapt现在处于\xe2\x80\x9c维护模式\xe2\x80\x9d。但是，我\xe2\x80\x99ve遇到了一个问题：KSP未检测到Dagger Hilt注释，例如@Inject，@Binds和@Module，并且我\xe2\x80\x99m得到了\xe2\x80\ x9c无法解析符号\xe2\x80\x9d错误。

我正在使用 \xe2\x80\x9c Framework Quickstarts: Use Supabase with Android Kotlin \xe2\x80\x9d 文档测试与 Supabase 的连接，您可以在其中找到代码。我的 build.gradle.kts（模块）：

我的 build.gradle.kts（项目）：

\n

plugins {\n    id("com.android.application") version "8.1.2" apply false\n    id("org.jetbrains.kotlin.android") version "1.9.20" apply false\n    id("com.google.devtools.ksp") version "1.9.20-1.0.14" apply false\n}\n

我\xe2\x80\x99已经尝试清理和重建我的项目，验证我的依赖版本，并检查我的 Dagger Hilt 和 KSP 设置。我还查看了官方 KSP 文档和 Google 文档，但我还没有解决该问题。我预计迁移到 KSP 后，Dagger Hilt 注释将被正确检测到，并且代码将按预期工作。

终于解决了，我的错误是没有写

implementation 'com.google.dagger:hilt-android:2.48.1'

来自 build.gradle.kts （模块）的依赖项。我还在 build.gradle 文件中做了一些更改

现在它完全可以工作了。

我留下我的build.gradle.kts（模块）：

}

    applicationId = "com.xxxxx.xxxxx"
    minSdk = 24
    targetSdk = 33
    versionCode = 1
    versionName = "1.0"

    testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables {

    }
}

buildTypes {

和我的 build.gradle.kts （项目）

all sub-projects/modules.
