How to solve the problem – could not resolve all artifacts for configuration classpath? I have the sample detail:

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

While I was running it, I found the warning message:

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

That is my question in my midterm exam, and it is urgent. I searched the solutions on some websites, but I didn’t get it. I may miss any line or other changes. I appreciate your assistance!

    The cause:
    The reason of this error is updating the Gradle. The Android Studio always asks you to update it, but don’t do this for unstable apps.
    Solution:
    I solved this problem by changing proxyPort from 8080 to jcenter and useing Maven instead of Maven. However, I had to test to use HTTPS instead of HTTPS. This is the build.gradle to build script and allprojects.

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

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

    Recently, I updated Gradle and the plugin version and it gave me some troubles. It was complaining about plugin com.android.application. I did some research and found the best solution is replacing:

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

    by

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

  2. Locate and replace: 

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

    to: 

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