找不到参数[com . Android . support:app compat-V7:25 . 0 . 0]的方法compile()

Question

正在尝试构建react本机项目，无法编译appcompat

找不到方法compile（）参数[com.android.support： appcompat-v7:25.0.0]类型的对象org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 21
        compileSdkVersion = 28
        targetSdkVersion = 27
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        compile 'com.android.support:appcompat-v7:25.0.0'
        compile 'com.android.support:support-annotations:25.0.0'
        compile 'com.android.support:design:25.0.0'
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
            url "$rootDir/../node_modules/expo-camera/android/maven"
        }
    }
}


task wrapper(type: Wrapper) {
    gradleVersion = '4.7'
    distributionUrl = distributionUrl.replace("bin", "all")
}

更新更改为实施结果

ERROR: Could not find method implementation() for arguments [com.android.support:appcompat-v7:25.0.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler

Answer 1

顶级build.gradle文件是依赖项的错误位置。它甚至在代码中的注释中声明：

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files

您应该将这些行移动到另一个build.gradle文件（在您的模块中）

Answer 2

gradle 中的 compile 关键字已被弃用，取而代之的是实现。

Answer 3

针对编译使用实现。

testImplementation用于测试编译。

运行时仅针对运行时使用。

 implementation 'com.android.support:appcompat-v7:25.0.0'
    implementation 'com.android.support:support-annotations:25.0.0'
    implementation 'com.android.support:design:25.0.0'

这些行将不会进入build . gradle(Project:Project name)中

   apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.waltonbd.myapplication"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/raw'] } }
}


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

还有一个是build.gradle(项目:Projectname)。不要进入这里。

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

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