Could not resolve all dependencies for configuration ':classpath'

Question

I cant seem to get build tools for the latest gradle at all. I suspect its something to do with proxy setting for gradle. I have had a good look online but still cant seem to find a solution. I use gradle 2.1.

I created gradle.properties file in my /home/user/.gradle folder with these setting.

systemProp.http.proxyHost=proxy systemProp.http.proxyPort=80 systemProp.http.proxyUser=myusername systemProp.http.proxyPassword=password

systemProp.https.proxyHost=proxy systemProp.https.proxyPort=80 systemProp.https.proxyUser=myusername systemProp.https.proxyPassword=password

Here is my global build.gradle

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:0.13.0'
        classpath fileTree(dir: 'build-libs', include: '*.jar')
    }
}


allprojects {
    repositories {
        mavenCentral()
    }
}

And here is the error i get when running gradlew

Could not HEAD 'https://repo1.maven.org/maven2/com/android/tools/build/gradle/0.13.0/gradle-0.13.0.pom'.
peer not authenticated

What am I missing? that maven link opens fine in a browser.

Answer 1

Right, I'm not sure if it will work for others but worked for me.

I changed proxyPort to 8080 and used jcenter instead of Maven. But I had to apply expeption to use HTTP instead of HTTPS. This is what I have in my build.gradle for build script and allprojects

buildscript {
  repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

allprojects {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

UPDATE: 06/08

I have recently updated Gradle and plugin version and had some problems. It was complaining about plugin com.android.application

I did some digging around and changed

 jcenter {
    url "http://jcenter.bintray.com/"
}

to

repositories {
    maven { url 'http://repo1.maven.org/maven2' }
}

Answer 2

Find and Replace:

jcenter()
maven {
    url "https://maven.google.com"
}

to:

maven {
    url "https://maven.google.com"
}
jcenter()

Answer 3

For newer android studio 3.0.0 and gradle update, this needed to be included in project level build.gradle file for android Gradle build tools and related dependencies since Google moved to its own maven repository.

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

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

        // NOTE: Do not place your application dependencies here; they belong
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

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