android - Jetpack Compose 无法编译应用程序，找不到 kotlin-compiler

Question

最近我一直在努力让 jetpack compose 运行......我已经按照所有示例代码，下载了 canary 和所有，但是 1.4.0 插件对我不起作用，我遇到了编译问题
这些是我的 gradle 文件

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = "1.4.0"
    ext.compose_version = '1.0.0-alpha01'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.0-alpha08"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

和

plugins {
    id 'com.android.application'
    id 'kotlin-android'
}

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.example.jetexample"
        minSdkVersion 21
        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 {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = '1.8'
    }
    buildFeatures {
        compose true
    }
    composeOptions {
        kotlinCompilerExtensionVersion kotlin_version
        kotlinCompilerVersion compose_version
    }
}

dependencies {

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

    implementation 'androidx.core:core-ktx:1.3.1'
    implementation 'androidx.appcompat:appcompat:1.2.0'

    //Fundamental building blocks of Compose's programming model and state management, and core runtime for the Compose Compiler Plugin to target.
    implementation "androidx.compose.runtime:runtime:$compose_version"

    //Fundamental components of compose UI needed to interact with the device, including layout, drawing, and input.
    implementation "androidx.compose.ui:ui:$compose_version"

    //Build Jetpack Compose UIs with ready to use Material Design Components. This is the higher level entry point of Compose, designed to provide components that match those described at www.material.io.

    //Build animations in their Jetpack Compose applications to enrich the user experience.
    implementation "androidx.compose.animation:animation:$compose_version"

    //In charge of annotators like @Preview and tooling for render views
    implementation "androidx.ui:ui-tooling:$compose_version"

    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

我得到的错误是这个

我已经尝试过这个版本，我遵循了文档、jet news 示例和所有内容，但我无法编译项目，我做错了什么？

Answer 1

我与 compileOptions 不匹配

 composeOptions {
        kotlinCompilerExtensionVersion kotlin_version
        kotlinCompilerVersion compose_version
    }

应该

composeOptions {
        kotlinCompilerExtensionVersion compose_version
        kotlinCompilerVersion kotlin_version
    }
