android - 升级后Android Studio连接超时

Question

我已经将Android Studio从版本3升级到了3.1.2。在执行更新之前，该项目已成功构建，但是此后，每次我尝试同步项目(以进行构建)时，都会说

Connection timed out: connect

配置文件还没有。

gradle-wrapper.properties:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

应用程式(build.gradle):

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "st94.gmail.com.karaokegenerator"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
//        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:27.1.0'
    implementation 'com.android.support:design:27.1.0'
    implementation 'com.mcxiaoke.volley:library:1.0.19'
    implementation "commons-io:commons-io:+"
    implementation 'com.github.castorflex.smoothprogressbar:library-circular:1.2.0'
    implementation 'com.google.code.gson:gson:2.6.2'
    implementation 'com.github.recruit-lifestyle:PlayPauseButton:1.0'
    implementation 'pub.devrel:easypermissions:1.2.0'

}

项目(build.gradle):

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

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'

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

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://jitpack.io"
        }
    }
}

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

我已经测试过创建一个新项目并测试4.7的gradle版本，但没有任何更改。我已经用谷歌搜索了很多，但没有发现。完整的错误消息是这样的:

您是否也升级了.gradle文件。您需要包括在项目中导入的所有最新libraries版本。

Build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 27



defaultConfig {
    applicationId "appId"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1"
    multiDexEnabled true
    vectorDrawables.useSupportLibrary = true
    testInstrumentationRunner 
  "android.support.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.android.support:design:27.1.1'
testImplementation 'junit:junit:4.12'
implementation 'com.android.support:multidex:1.0.3'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

allprojects {
    repositories {

        maven { url "https://jitpack.io" }
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

如果仍然出现此问题，请先 delete/clean您的 intermediate文件夹，然后 clean/invalidate并重新启动，希望它可以解决您的问题。
