java - 无法解析 org.roboguice :roboguice:3. +

Question

这是我的 build.gradle 文件:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.2'
    }
}
apply plugin: 'com.android.application'

repositories {
    jcenter()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.1.0"

    defaultConfig {
        applicationId "com.example.stopcall.app"
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.0.3'
    compile 'org.roboguice:roboguice:3.+'
    provided 'org.roboguice:roboblender:3.+'
}

我不知道为什么，但有时我在构建时会遇到此错误:

   > Could not resolve org.roboguice:roboguice:3.+.

what can it be? as it can happen in a specific hour and few hours later (maybe another network) it might be fixed.

有什么想法吗？

你有代理吗？如果是这样，请检查您的 gradle 属性文件

在 C:\Users\.gradle\下创建一个包含代理详细信息的 gradle.properties 文件:

systemProp.http.proxyHost=hostname
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=username
systemProp.http.proxyPassword=xxx

systemProp.https.proxyHost=hostname
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=username
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=localhost
