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......我已经遵循了所有示例代码，下载了金丝雀等等，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.
    implementation "androidx.compose.material:material:$compose_version"
    implementation "androidx.compose.material:material-icons-extended:$compose_version"

    implementation "androidx.compose.foundation:foundation:$compose_version"
    implementation "androidx.compose.foundation:foundation-layout:$compose_version"

    //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，我已经按照文档、jet news 示例以及所有内容进行操作，但是我无法编译该项目，我做错了什么？

Answer 1

我错配了 compileOptions

 composeOptions {
        kotlinCompilerExtensionVersion kotlin_version
        kotlinCompilerVersion compose_version
    }

应该

composeOptions {
        kotlinCompilerExtensionVersion compose_version
        kotlinCompilerVersion kotlin_version
    }
