找不到参数的方法ksp()

Question

我刚刚开始在Kotlin中学习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在我的数据库中存储已保存的笔记，所以我正在检查开发人员。我们有一些必要的依赖，我们必须添加到我们的build.gradle(模块)如上所述developer.android.com https://developer.android.com/training/data-storage/room#kts但是当我添加这些依赖项时，我有一个错误，我无法找出

在object类型org.gradle.api.internal.artifact .dsl.dependencies. defaultdependencyhandler

找不到参数[androidx.room:room-compiler:2.4.3]的方法ksp()

我与kapt有类似的错误，但我通过在我的build.gradle(模块)中添加必要的插件来解决它。现在我正在从我的构建中删除此实现。Gradle和前进的测试项目，但任何帮助将是感激的，谢谢。

在developer.android.com中提到的依赖项

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build.gradle(模块)

Answer 1

项目gradle.build

在plugins{ ... }块中将kotlin gradle插件升级到1.8.0。

// Project level build file
plugins {
...
id 'org.jetbrains.kotlin.android' version '1.8.0' apply false
}

在App(module)上gradle.build文件中不需要设置kapt()，只需在dependencies{ ... }块中添加ksp()，并设置KSP插件

// App module build file
plugins{
...
id 'com.google.devtools.ksp' version '1.8.0-1.0.8'
}
dependencies {

...
// You don't need this
// kapt("androidx.room:room-compiler:$room_version")
ksp("androidx.room:room-compiler:$room_version")
...
}

Answer 2

确保您的kotlin gradle插件版本为1.8.0或更高

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

在应用级gradle文件中添加依赖项

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

最后，构建项目。

Answer 3

根据本文档

首先，在你的顶级build.gradle.kts文件中声明KSP插件。确保选择与项目Kotlin版本一致的KSP版本

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

然后，在模块级build.gradle.kts文件中启用KSP:

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

Answer 4

首先，您需要在您的顶级构建(项目)中声明KSP插件。gradle。kt文件。请确保您选择的KSP版本与项目的Kotlin版本一致。

如果你正在使用Kotlin - build.gradle.kts(项目级别)

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

如果你正在使用Groovy- build.gradle(项目级别)

plugins {
id 'com.google.devtools.ksp' version '1.8.10-1.0.9' apply false
}

然后启用KSP在模块级或应用级的build.gradle.kts文件中:

Kotlin - build.gradle.kts(模块级或应用级)

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

Groovy - build.gradle(模块级或应用级)

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

用KSP替换注释处理器

//For .kts
dependencies {
//When you have no dependencies included with kapt in your module anymore, remove the kapt plugin.
//kapt("androidx.room:room-compiler:2.5.0")
ksp("androidx.room:room-compiler:2.5.0")
}
//For Groovy
dependencies {
//When you have no dependencies included with kapt in your module anymore, remove the kapt plugin.
//kapt 'androidx.room:room-compiler:2.5.0'
ksp 'androidx.room:room-compiler:2.5.0'
}

您还应该删除与kapt相关的任何剩余配置。

Answer 5

你可能会从Google codelab找到答案

1-添加插件到app/build.gradle

plugins {
...
// ksp for room
id 'com.google.devtools.ksp' version "1.8.21-1.0.11"
}

2-添加app/build.gradle中的依赖项

dependencies {
...
def room_version = "2.5.1"
implementation "androidx.room:room-runtime:$room_version"
ksp "androidx.room:room-compiler:$room_version"
implementation "androidx.room:room-ktx:$room_version"
}
