摇篮。 无法构建简单的Android项目

Question

I have starting to learn a Gradle and try to make a first build.gradle file

println 'Build start.'
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
println 'Current gradle version : '+gradle.gradleVersion
apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
}

android {
    compileSdkVersion 15
    buildToolsVersion '19.0.0'

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs ['src','src_default']
            res.srcDirs ['res']
        }
        androidTest.setRoot('tests')
    }
}

After gradle build :

> Could not resolve all dependencies for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:0.4.
     Required by:           
         :hello_gradle:unspecified
      > Could not GET 'https://repo1.maven.org/maven2/com/android/tools/build/gradle/0.4/gradle-0.4.pom'.
         > peer not authenticated

* Try:                      
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

After gradle clean :

* Where:                    
Build file '/home/sergey/Documents/dev_master/hello_gradle/build.gradle' line: 11

* What went wrong:          
A problem occurred evaluating root project 'p4_common_platform'.
> Failed to apply plugin [id 'android']
   > Could not create plugin of type 'AppPlugin'.

After gradle clean --stacktrace :

* Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating root project 'p4_common_platform'.

What i'm doing wrong?

After several attempts trying to build my first Gradle project, I was stack with several problems and I would like to share few tips :

• First of all, make sure that you are using valid Gradle build system. I mean a valid version of Gradle to build android project. The build file which you can see above, I built it with the next configuration :

 ------------------------------------------------------------ Gradle 1.10 ------------------------------------------------------------ Build time: 2013-12-17 09:28:15 UTC Build number: none Revision: 36ced393628875ff15575fa03d16c1349ffe8bb6 Groovy: 1.8.6 Ant: Apache Ant(TM) version 1.9.2 compiled on July 8 2013 Ivy: 2.2.0 JVM: 1.7.0_55 (Oracle Corporation 24.51-b03) OS: Linux 3.13.0-32-generic amd64 

• Make sure that old version of Gradle was removed from your local machine. Why? Because no guarantee that both Gradle versions will not conflict together.

• Make sure that your build.gradle file is correct and does not contain invalid logic (incorrect dependencies, valid markup structure, etc.)
