摇篮项目刷新失败 - 协议家族不可用 [英] Gradle project refresh failed - Protocol family unavailable

问题描述

今天早上我已经从SVN更新我的Andr​​oid项目，增加code的一些新的线路和测试：一切做工精细

This morning I've updated from SVN my Android project, added some new lines of code and tested: everything work fine.

后来我试了几分钟的时间我的设备上再次运行应用程序，但现在Android的工作室告诉我：

A couple of minutes later I've tried to run again the application on my device but now Android Studio tells me:

Gradle 'iSfa' project refres failed
Error: protocol family unavailable

的build.gradle 的内容是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion '19.1.0'

    packagingOptions {
        exclude 'LICENSE'
        exclude 'NOTICE'
        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/notice.txt'
    }

    defaultConfig {
        applicationId "it.gn.sfa"
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    mavenCentral()
    maven {
        url "http://JRAF.org/static/maven/2"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile files('libs/android-support-v4-r10.jar')
    compile files('libs/android-support-v4.jar')
    compile 'com.fasterxml.jackson.core:jackson-core:2.3.2'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.3.2'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
    compile 'org.springframework.android:spring-android-rest-template:1.0.1.RELEASE'
    compile 'org.springframework.android:spring-android-core:1.0.1.RELEASE'
    compile 'org.jraf:android-switch-backport:1.3.1'
}

和gradle这个设置的内容是：

And the content of gradle settings is:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.12.+'

    }
}

allprojects {
    repositories {
        jcenter()
    }
}

请注意：我使用的是最新版本的Andr​​oid工作室，发布0.8.6和gradle这个最新版本，版本0.12.2提供

Note: I'm using the latest version of Android Studio, release 0.8.6, and the latest version of gradle, release 0.12.2.

删除 .gradle 文件夹不解决任何问题。

Deleting the .gradle folder don't solve anything.

推荐答案

由OP找到解决方法：

删除 .gradle 文件夹，关闭Windows的防火墙和重建项目（与gradle这个资料库的完整下载）对我来说工作得很好。

Deleting .gradle folder, turn off Windows' firewall and rebuild project (with a complete download of the gradle repository) worked fine for me.
