Question

正如标题所示，当我尝试在设备上进行部署时，我无法理解问题出在哪里。

当我尝试将 kotlinCompilerExtensionVersion '1.0.0-beta06' 添加到 gradle 时，部署失败并且错误消息是“无法解析配置的所有文件'：app：kotlin-extension'。找不到androidx.compose：compose-compiler：1.0.0-beta06。”

我想要做的是从现有项目开始添加一段用 compose 编写的代码，我正在遵循本指南 https://developer.android.com/jetpack/compose/interop/interop-apis

我将我的gradle粘贴在下面：

Answer 1

我昨天遇到了这个问题。我所做的是在撰写选项中添加编译器。

composeOptions {

       kotlinCompilerVersion "1.4.32"
       kotlinCompilerExtensionVersion "1.0.0-beta06"
   }

在 stackoverflow here 中发现与您有些类似的问题。您可能需要升级您的 gradle 版本。

还有here，（如果你还没有）在项目gradle中设置ext.kotlin_version = .....

buildscript {
    ext.kotlin_version = "1.4.32"
    ext {  ....   }

    repositories {
        mavenCentral()
        google() 
    }

    allprojects {
        repositories {
            mavenCentral()
            google()
            maven { url "https://jitpack.io" }
        }
    }

}

Answer 2

终于找到问题了。

在我使用的 build.gradle（项目级别）中：

classpath "com.android.tools.build:gradle:$gradle_version"

所以创建新的 Compose 项目我找到了解决问题的方法。特别是：

build.gradle（项目级别）就像：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
        maven {
            url = uri("https://plugins.gradle.org/m2/")
        }
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.0-alpha15"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.32"
        classpath "org.jlleitschuh.gradle:ktlint-gradle:$ktlint_version"
        classpath("androidx.navigation:navigation-safe-args-gradle-plugin:2.3.5")
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

build.gradle（应用级别）就像：

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-parcelize'
    id 'kotlin-kapt'
    id 'androidx.navigation.safeargs'
}

android {
    compileSdkVersion rootProject.findProperty("android.compileSdkVersion") as Integer
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId findProperty("android.applicationId")
        targetSdkVersion findProperty("android.targetSdkVersion") as Integer
        minSdkVersion findProperty("android.minSdkVersion") as Integer
        versionCode findProperty("android.minSdkVersion") as Integer
        versionName findProperty("android.versionName")
        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'
        useIR = true
    }
    buildFeatures {
        dataBinding true
        compose true
    }
    composeOptions {
        kotlinCompilerExtensionVersion compose_version
        kotlinCompilerVersion '1.4.32'
    }
}

    implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
    implementation 'androidx.activity:activity-compose:1.3.0-alpha07'

    // Kotlin
    implementation "androidx.fragment:fragment-ktx:$fragment_version"

    // Coroutines
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-play-services:$coroutine_version"
    implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:$coroutine_version"

    // Timber
    implementation "com.jakewharton.timber:timber:$timber_version"

    // Glide
    implementation "com.github.bumptech.glide:glide:$glide_version"

    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

并使用嵌入式 JDK 将 JDK 升级到 11

最后将 gradle 升级到 7.0.0
