java - 无法获取 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.0.2/gradle-7.0.2.pom'

Question

我是 Android Studio 的新手，每次我尝试将项目与 gradle 同步时都会收到此错误。例如，我提供了对三个文件的引用。

1)项目级build.gradle文件

plugins {
    id 'com.android.application'
    id 'kotlin-android'
}

android {
    compileSdk 31

    defaultConfig {
        applicationId "com.example.myfirstapp"
        minSdk 24
        targetSdk 31
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    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'
    }
}

dependencies {

    implementation 'androidx.core:core-ktx:1.7.0'
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.1'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

2) Gradle Scripts build.gradle 文件

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        mavenCentral()
        mavenLocal()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:7.0.2"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.6.0-RC2"

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

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

3) gradle-wrapper.properties

#Fri Nov 05 11:37:25 IST 2021
distributionBase=GRADLE_USER_HOME
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.2-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

我在 Windows 10 上安装了 Android Studio Arctic Fox 2020.0.1 补丁 3

我得到的完整错误信息是

Could not GET 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.0.2/gradle-7.0.2.pom'. Received status code 405 from server: Method Not Allowed

Answer 1

好吧，看起来没问题，我只能猜测是连接问题。

尝试使用此链接 https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.0.2/gradle-7.0.2.pom使用浏览器以确保您可以连接到 google。

如果您可以访问该站点，那么您可能需要使用代理/vpn。

下载psiphon的方法并导航到设置，例如将本地端口设置为 1234。

然后转到 Users/%USERNAME%/.gradle 并使用以下内容添加 gradle 属性

systemProp.http.proxyHost=127.0.0.1
systemProp.http.proxyPort=1234

systemProp.https.proxyHost=127.0.0.1
systemProp.https.proxyPort=1234
