在类型为 org.gradle.api.internal.artifacts.dsl.dependencies 的对象上找不到参数 [目录 'libs'] 的方法实现 ()

Question

我在安装了Android Studio项目中安装DART和扑朔迷离后遇到了失败的成绩构建问题。我尝试创建一个新的Flutter应用程序，但它一直在构建中，所以我不得不停止它。在重新启动Android Studio时，我的等级拒绝为我拥有的每个现有项目构建。

错误消息

Answer 1

首先，您的行不正确 app build.gradle（您的问题上的基础），正确的一个应该是这样的：

apply plugin: 'com.android.application'
// You don't need a repository here
android {
  signingConfigs {
  }
  compileSdkVersion 28
  buildToolsVersion '28.0.3'
  defaultConfig {
    minSdkVersion 19
    targetSdkVersion 28
    multiDexEnabled true
    versionName '3.1'
    testInstrumentationRunner
    "android.support.test.runner.AndroidJUnitRunner"
    android {
      defaultConfig {
      }
    }
    versionCode 1
  }
  buildTypes {
    release {
      minifyEnabled false
      proguardFiles getDefaultProguardFile('proguard-android.txt'),
          'proguard-rules.pro'
    }
  }
  productFlavors {
  }
}
dependencies {
  implementation fileTree(include: ['*.jar'], dir: 'libs')
  androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
  })

  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:1.1.3'
  implementation 'me.biubiubiu.justifytext:library:1.1'
  implementation 'de.hdodenhof:circleimageview:2.2.0'
  implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.15'
  testImplementation 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

然后，您需要更新 root build.gradle，因为implementation仅适用于Android Build.gradle版本3.0。：

buildscript {
repositories {
    google()
    jcenter()
    mavenCentral()
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.3.1'
    classpath 'com.google.gms:google-services:4.2.0'
}
}
allprojects {
repositories {
    jcenter()
    mavenCentral()
    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
 }
}

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

您还需要将Gradle版本更新为4.1

请在Android Gradle插件发行说明

Answer 2

解决我在文件中进行更改的问题 - ＆gt;项目结构 - ＆GT;项目设置 - ＆GT;项目提到系统上最新的Android版本，在我的情况下为30。平台设置也是如此 - ＆gt;SDK提到了Android并纠正Java Home Path，然后在代码中我也进行了以下更改，对我有用。将gradleexception更改为filenotfoundexception，然后我能够编译。

//throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
throw new FileNotFoundException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
