Trying to create room database with android, but keep getting dependency error

我正在关注 android developers tutorial实现本地房间数据库。
我目前正在处理 设置 因此改变了我的依赖。
但是,一旦我同步了应用程序 build.gradle,它就会引发错误。
A problem occurred evaluating project ':app'.
> Could not find method ksp() for arguments [androidx.room:room-compiler:2.3.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
如何将其指向 ksp() 方法?以前我对 kapt() 有同样的问题,但通过添加
id kotlin-kapt
解决了它但我还没有找到 ksp() 所需的依赖项。我的应用程序 build.gradle 看起来像这样。相应部分位于代码 fragment 的下部,并标有
//rooom <---------
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
//Room
id 'kotlin-kapt'
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.3"
defaultConfig {
applicationId "com.example.testapplication"
minSdkVersion 24
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {

}
kotlinOptions {
jvmTarget = '1.8'
}
}

// To use Kotlin annotation processing tool (kapt)

最佳答案
首先,您需要添加 ksp 插件 repo gradlePluginPortal
在您的项目 build.gradle
buildscript {
ext.ksp_version = "1.5.31-1.0.0"
ext.kotlin_version = "1.5.31"
repositories {
maven{ url 'https://dl.bintray.com/kotlin/kotlin-eap'}
maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
mavenCentral()
jcenter() // Warning: this repository is going to shut down soon
gradlePluginPortal()
google()
}
dependencies {
classpath "com.android.tools.build:gradle:7.0.2"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
//other dependencies here
}
}二、需要开启ksp插件
在您的应用程序 build.gradle
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'com.google.devtools.ksp' version "$ksp_version"
}
