在 build.gradle 中找不到参数 [com.android.tools.build:gradle:+] 的方法 classpath()

Question

您好，我是一名IT学生。我正在努力解决这个错误“在 org.gradle.api.internal.artifacts.dsl.dependency.DefaultDependencyHandler 类型的对象上找不到参数 [com.android.tools.build:gradle:+] 的方法 classpath()。 ”

我该如何解决这个问题？有人可以帮忙吗:<<<

这是我在APP中的Build.gradle文件

plugins {
    id "dev.flutter.flutter-gradle-plugin"
    id "com.google.gms.google-services"
    id 'com.android.application' version '8.4.0' apply false
    id 'com.android.library' version '8.4.0' apply false
    id 'org.jetbrains.kotlin.android' version '1.9.23' apply false
    
}

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

android {
    namespace "com.example.care_cove"
    compileSdk flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.care_cove"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

dependencies {
    compile 'com.google.firebase:firebase-core:16.0.5'

    compile 'com.google.firebase:firebase-database:16.0.5'

    compile 'com.google.firebase:firebase-auth:16.0.5'

    compile 'androidx.appcompat:appcompat:1.1.0'
}

flutter {
    source '../..'
}

这是我在项目或android中的build.gradle文件

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

dependencies{
    classpath 'com.android.tools.build:gradle:+'
    classpath 'com.google.gms:google-services:+'
}
rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

我尝试更改版本但仍然不起作用

Answer 1

classpath

是

dependencies

块的

buildscript

块中可用的配置。可以将依赖项放置在构建脚本本身的类路径上。

所以你可能想写这样的东西：

buildscript {
    repositories {
        google()
    }
    dependencies{
        classpath 'com.android.tools.build:gradle:+'
        classpath 'com.google.gms:google-services:+'
    }
}

我添加了一个

repositories

块，因为您需要某种依赖项的源。

至于这些依赖项的确切意图和用途是什么，也许您应该回顾一下您正在遵循的任何教程或示例。
