在Gradle上创建新项目时，Android Studio陷入困境：配置项目或Gradle：Resolve Dependencies'：classpath：'

Question

Using the new project wizard to create a new Android application, The IDE gets stuck before I can even see the Code files. After trying to create many types of projects, It tells me that it is building and the IDE only shows a Loading box that says either:

Gradle: Configure Project 

or

Gradle: Resolve Dependencies ':classpath:'

I went out to lunch and when I came back I saw:

Error:Could not HEAD ' http://jcenter.bintray.com/com/android/tools/build/builder-model/0.12.1/builder-model-0.12.1.jar '. Received status code 500 from server: Internal Server Error Enable Gradle 'offline mode' and sync project

Answer 1

Bintray has experienced momentary timeouts yesterday due to a change to one of the cluster nodes in Dallas. It looks like you've happened to hit that exact node at that exact time.

The issue has been sorted out after a couple of minutes, so there is no real need to change anything on your side.

Actually, keeping jcenter() in your script is preferable since it's a super-set of Maven Central.

Answer 2

In order to solve it, I went to File -> Project Structure -> Project and changed:

Android Plugin Repository and Default Plugin Repository from their default values of

jCenter()

to

mavenCentral

Answer 3

I had a similar problem and was able to use both repositories by including them both in my build.gradle in my android directory:

allprojects {
    repositories {
        mavenCentral()
        jcenter()
    }
}

This is an adjustment to @MHDante's answer - instead of replacing one with the other, you can use both!

Answer 4

I was heaving the same/similar problem:

Error:A problem occurred configuring root project 'X'. Could not resolve all dependencies for configuration ':classpath'. Could not resolve com.android.tools.build:gradle:0.12.+. Required by: :X:unspecified Failed to list versions for com.android.tools.build:gradle. Could not list versions using M2 pattern ' http://jcenter.bintray.com/[organisation]/[module]/[revision]/[artifact]- revision.[ext]'. Could not GET ' http://jcenter.bintray.com/com/android/tools/build/gradle/ '. Received status code 401 from server: Authorization Required

But I resolved it by calling synchroise and then rebuilding the project.
