Can't resolve dependency in Android Studio with jcenter

Question

Why my program hang on resolving dependency for appDebug in andorid studio? I can\'t resolve any library.

This is my root gradle file:

buildscript {
rep         


        

Answer 1

I faced the exact same issue when I tried to include in my build.gradle the following dependency classpath 'com.google.gms:google-services:3.0.0' in order to have

buildscript {
  repositories {
      jcenter()
  }

  dependencies {
      classpath 'com.android.tools.build:gradle:2.3.0'
      classpath 'com.google.gms:google-services:3.0.0'
  }
}

I got Timeout on gradle resolution path. So far (when only the classpath to the gradle:2.3.0 was present), I in fact was working with my cache, so I didn't notice that my proxy was not correctly set.

So I tried to select manual proxy: Settings->Apperance&Behaviour-> System Settings ->Http Proxy with Hostname and port number. So the associated gradle.properties was:

systemProp.http.proxyHost=proxy.com
systemProp.http.proxyPort=123    (123 is just an example)

but I still had the problem. Caramba!! So I noticed that the files I needed are located here:

https://jcenter.bintray.com/com/android/tools/build/gradle/2.3.0/

but Android studio does not provide a UI to set the proxy on HTTPS so I manually edit the gradle.properties to duplicate the line for https

systemProp.http.proxyHost=proxy.com
systemProp.http.proxyPort=123    (123 is just an example)
systemProp.https.proxyHost=proxy.com
systemProp.https.proxyPort=123  

And.... it works for me. Don't need to change jcenter to mavenCentral.
