Gradle 找不到 Android Compose 编译器

Question

我对这个问题感到非常困惑。我的gradle文件中有以下几行：

implementation "androidx.compose.runtime:runtime:1.0.0-alpha04"
implementation "androidx.compose.compiler:compiler:1.0.0-alpha04"
implementation "androidx.compose.runtime:runtime-rxjava2:1.0.0-alpha04"

但是，当我构建时，出现以下错误：

Could not determine the dependencies of task ':app-name-omitted:prepareDebugKotlinCompileTask'.
> Could not resolve all task dependencies for configuration ':app-name-omitted:kotlin-extension'.
   > Could not find androidx.compose:compose-compiler:1.0.0-alpha04.
     Searched in the following locations:
       - https://dl.google.com/dl/android/maven2/androidx/compose/compose-compiler/1.0.0-alpha04/compose-compiler-1.0.0-alpha04.pom
       - https://repo.maven.apache.org/maven2/androidx/compose/compose-compiler/1.0.0-alpha04/compose-compiler-1.0.0-alpha04.pom
       - https://jcenter.bintray.com/androidx/compose/compose-compiler/1.0.0-alpha04/compose-compiler-1.0.0-alpha04.pom
     Required by:
         project :app-name-omitted

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

我对此感到困惑，因为编译器确实存在于 Google 的 repo 中：https ://maven.google.com/web/index.html#androidx.compose.compiler:compiler

如有必要，我可以发布更多信息，但我想保持简单。即使 compose 设置完全错误，为什么也找不到 POM 文件？

Answer 1

有同样的问题并在将 gradle 版本更新为

classpath "com.android.tools.build:gradle:4.2.0-alpha14"

而不是kotlinCompilerExtensionVersion在 composeoptions中声明编译器版本，而是声明为依赖项

implementation "androidx.ui:ui-tooling:$compose_version"
implementation "androidx.compose.runtime:runtime:$compose_version"
implementation "androidx.compose.compiler:compiler:$compose_version"

Answer 2

我最近遇到了同样的问题。某些 Compose 编译器版本支持特定的 Kotlin 版本。

感谢 @Braian 的Compose 编译器

Compose 到 Kotlin 兼容性图

就我而言，以下版本有效。

compose_version = '1.3.0-alpha01'

和

kotlinCompilerExtensionVersion "1.2.0-beta03"

这是我的 gradle 文件供参考。

构建.gradle（：应用程序）

plugins {
    id 'com.android.application'
    id 'org.jetbrains.kotlin.android'
}

android {
    compileSdk 32

    defaultConfig {
        applicationId "com.hometech.composedemo"
        minSdk 21
        targetSdk 32
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        vectorDrawables {
            useSupportLibrary true
        }
    }

    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 "1.2.0-beta03"
    }
    packagingOptions {
        resources {
            excludes += '/META-INF/{AL2.0,LGPL2.1}'
        }
    }
}

dependencies {

    implementation 'androidx.core:core-ktx:1.8.0'
    implementation "androidx.compose.ui:ui:$compose_version"
    implementation "androidx.compose.material:material:$compose_version"
    implementation "androidx.compose.ui:ui-tooling-preview:$compose_version"
    implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.5.0'
    implementation 'androidx.activity:activity-compose:1.5.0'
    implementation 'androidx.navigation:navigation-runtime-ktx:2.5.0'

    def nav_version = "2.5.0"
    // Navigation Compose
    implementation("androidx.navigation:navigation-compose:$nav_version")

    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
    androidTestImplementation "androidx.compose.ui:ui-test-junit4:$compose_version"
    debugImplementation "androidx.compose.ui:ui-tooling:$compose_version"
    debugImplementation "androidx.compose.ui:ui-test-manifest:$compose_version"

    //Icons
    implementation "androidx.compose.material:material-icons-extended:$compose_version"
}

build.gradle（项目级别）

buildscript {
    ext {
        compose_version = '1.3.0-alpha01'
    }
}// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.2.1' apply false
    id 'com.android.library' version '7.2.1' apply false
    id 'org.jetbrains.kotlin.android' version '1.6.21' apply false
}

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

Compose 版本“1.3.0-alpha01”的最新更改

编译器版本

kotlinCompilerExtension版本 '1.3.0'

科特林版本

id 'org.jetbrains.kotlin.android' 版本 '1.7.10' 应用 false

Answer 3

您应该将编译器版本添加到应用程序的build.gradle：

android {
    ...
    composeOptions {
        kotlinCompilerExtensionVersion '1.3.0'
    }
}

版本应与 Kotlin 版本匹配，例如 Kotlin1.7.10应与 compose compiler 一起使用1.3.0。请参考此地图找到正确的匹配：https://developer.android.com/jetpack/androidx/releases/compose-kotlin

Answer 4

我不得不升级我的 Gradle 版本：

buildscript {
    dependencies {
         classpath "com.android.tools.build:gradle:7.0.0-alpha02"
