I have been struggling to add Room dependencies for a couple of days now(not proud). There is always an error no matter what i try. I am not the most experienced though.

几天来，我一直在努力添加Room Dependents(并不自豪)。无论我怎么尝试，总会有错误。不过，我不是最有经验的人。

I added the below from the Android docs site.

我从Android文档站点添加了以下内容。

`val room_version = "2.5.2"

`val Room_Version=“2.5.2”

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

//1
// To use Kotlin annotation processing tool (kapt)
kapt("androidx.room:room-compiler:$room_version")

//2
// To use Kotlin Symbol Processing (KSP) (2)
ksp("androidx.room:room-compiler:$room_version")

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

All depencdencies can resolve except what is marked 1 & 2.
For 1, i get
Type mismatch. Required: KaptOptions Found: String

除标记为1和2的依赖项外，所有依赖项都可以解析。对于1，我得到类型不匹配。必需：找到KaptOptions：字符串

For 2, i get
Unresolved reference: ksp

对于2，我得到了未解析的引用：KSP

I added these to my plugins from searches i did but to no avail.
` id("com.google.devtools.ksp") version "1.8.21-1.0.11"
kotlin("android")

我把这些从搜索中添加到我的插件中，但无济于事。` id（“com.google.devtools.ksp”）version“1.8.21-1.0.11”kotlin（“android”）

// Apply the Room and Kotlin Kapt plugins
kotlin("kotlin-kapt")
id("androidx.room.room-compiler")`

I had the same issue 3 months ago, my solution was this:

3个月前我也遇到过同样的问题，我的解决方案是：

At the top of the build.gradle (:app) inside plugins

在build.gradle(：应用程序)内部插件的顶部

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
    id 'kotlin-kapt'
}

And then in your dependencies, same file

然后在您的依赖项中，相同的文件

/* ROOM */
def roomVersion = "2.5.2" //this was 2.5.1 back then
implementation "androidx.room:room-ktx:$roomVersion"
kapt "androidx.room:room-compiler:$roomVersion"

Finally, check if Android Studio wrote a Room dependency for you before and delete it:

最后，检查Android Studio之前是否为您编写了Room Dependent并将其删除：

implementation 'androidx.room:room-common:2.5.2'

What properly worked was following the migration guide at
Migrate from kapt to KSP

正确的做法是遵循从KAPT迁移到KSP的迁移指南

I used

我以前

ksp("androidx.room:room-compiler:$room_version")

Added the below to the project level build.grradle

将以下内容添加到项目级构建中。grradle

plugins {
id("com.google.devtools.ksp") version "1.8.10-1.0.9" apply false}

Added the below to the module level build.gradle

在模块级别build.gradle中添加了以下内容

plugins {
id("com.google.devtools.ksp")}

And remove everything added for the kapt

并删除为Kapt添加的所有内容

1. Open your project build.gradle.


2. Add the plugin com.google.devtools.ksp with the correct version:

    ...
    plugins {
        ...
        // x.y.z must be THE SAME for all the kotlin/ksp plugins.
        // (My version is 1.9.10)
        id "org.jetbrains.kotlin.jvm" version 'x.y.z' apply false
        id "org.jetbrains.kotlin.android" version 'x.y.z' apply false
        ...
        // Choose an appropriate version from: 
        // https://github.com/google/ksp/releases
        id "com.google.devtools.ksp" version 'x.y.z-a.b.c' apply false
    }

3. Open your module build.gradle where you add room library.


4. Add com.google.devtools.ksp to plugins:

    plugins {
        ...
        id 'com.google.devtools.ksp'
    }

5. Replace kapt by ksp:

    ...
    dependencies {
        // delete kapt "androidx.room:room-compiler:$room_version"
        ksp "androidx.room:room-compiler:$room_version"
    }
