Android Studio：结构是否从jcenter移至其他位置（行家）

Question

Why I am not able to get the Fabric downloaded from within the Android Studio .

I am using AS 3.2
Gradle Version : 4.6
Android Plugin : 3.2.0

Below is my build script :

buildscript {
                repositories {
                    jcenter() {

        }
        google()
        maven {url 'https://maven.fabric.io/public'  }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'
        classpath 'io.fabric.tools:gradle:1.+'

    }
}



allprojects {
    repositories {
        google()
        jcenter() {

        }
        maven { url 'https://maven.fabric.io/public' }
    }
}

But I am getting 407 issues :

> Unable to load Maven meta-data from https://jcenter.bintray.com/io/fabric/tools/gradle/maven-metadata.xml.
            > Could not get resource 'https://jcenter.bintray.com/io/fabric/tools/gradle/maven-metadata.xml'.

https://jcenter.bintray.com/io/fabric/tools/gradle/maven-metadata.xml .>> doesnt open

https://dl.google.com/dl/android/maven2/io/fabric/tools/gradle/maven-metadata.xml .>> gives 404 Error

https://maven.fabric.io/public/io/fabric/tools/gradle/maven-metadata.xml .>> gives the atatched Image

I am behind the Proxy and able to download sdk and Build tools.

Answer 1

You are receiving a proxy error:

Received status code 407 from server: Proxy Authentication Required

You can configure gradle to authenticate at the proxy by setting some properties at the gradle.properties file:

Configuring an HTTP proxy using gradle.properties

systemProp.http.proxyHost=www.somehost.org
systemProp.http.proxyPort=8080
systemProp.http.proxyUser=userid
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

There are separate settings for HTTPS. Configuring an HTTPS proxy using gradle.properties

systemProp.https.proxyHost=www.somehost.org
systemProp.https.proxyPort=8080
systemProp.https.proxyUser=userid
systemProp.https.proxyPassword=password
systemProp.https.nonProxyHosts=*.nonproxyrepos.com|localhost

Sometimes, especially in corporate environments, one might need to add the corporate repository to the repository configuration.

repositories {
    maven {
        url "http://corp.repository.net/libs"
    }
    jcenter()
    google()
}
