【中文标题】当我尝试同步我的 Gradle 文件时出现错误【英文标题】:When I try to sync my Gradle files I get an error 【发布时间】:2020-03-19 21:11:06 【问题描述】:我目前正在构建一个 Flutter 应用程序,到目前为止几乎一切正常,直到我开始收到此错误。我在整个互联网上搜索了一个解决方案,但我没有找到任何可以为我解决它的东西。
:
ERROR: Gradle DSL method not found: 'classpath()'
Possible causes:
The project 'android' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 3.5.2 and sync project
The project 'android' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file
The build file may be missing a Gradle plugin.
Apply Gradle plugin
我无法按“将插件升级到版本 3.5.2 并同步项目”,因为它失败了。
当我尝试构建我的应用程序时出现此错误

* Error running Gradle:

这是项目杠杆 build.gradle 文件:
buildscript
ext.kotlin_version = '1.3.50'
repositories
google()
jcenter()
dependencies
classpath 'com.android.tools.build:gradle:3.5.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.3'
dependencies
classpath 'com.android.tools.build:gradle:3.5.2'
allprojects
repositories
google()
jcenter()
rootProject.buildDir = '../build'
subprojects
project.buildDir = "$rootProject.buildDir/$project.name"
subprojects
project.evaluationDependsOn(':app')
task clean(type: Delete)
delete rootProject.buildDir
这是应用级别的 build.gradle 文件:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists())
localPropertiesFile.withReader('UTF-8') reader ->
localProperties.load(reader)
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null)
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null)
flutterVersionCode = '1.0.0'
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null)
flutterVersionName = '1.0'

奇怪的是我没有任何 Gradle 设置,见图片 LINK this is my gradle settings, as you see, all I get is this
我曾尝试迁移到 Android X,但没有成功。我只是说“没有找到用途”
【问题讨论】:
【参考方案1】:在项目级别build.gradle
有一个重复的类路径:
dependencies
classpath 'com.android.tools.build:gradle:3.5.2'
请删除buildscript
块之外的第二个匹配项并尝试重新构建。
