同行未通过身份验证：在 Android Studio 中构建应用程序时出错

Question

我一直在尝试构建使用 fabric.io 的 crashlytics 的应用程序。但是构建失败并出现下面提到的错误。

Executing tasks: [clean, :app:generateDebugSources, :app:generateDebugAndroidTestSources]

Configuration on demand is an incubating feature.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:classpath'.
   > Could not resolve io.fabric.tools:gradle:1.+.
     Required by:
         TestProject18July2016:app:unspecified
      > Could not resolve io.fabric.tools:gradle:1.+.
         > Failed to list versions for io.fabric.tools:gradle.
            > Unable to load Maven meta-data from https://maven.fabric.io/public/io/fabric/tools/gradle/maven-metadata.xml.
               > Could not GET 'https://maven.fabric.io/public/io/fabric/tools/gradle/maven-metadata.xml'.

我的互联网在代理服务器后面。我在 gradle.properties 文件中启用了 HTTP 和 HTTPS 设置。

我的 build.gradle 文件如下：

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

我的 app.gradle 文件如下：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}


android {
    compileSdkVersion 23
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "testfirebase.kishor.testproject18july2016"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
  /*  testCompile 'junit:junit:4.12'*/
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile('com.crashlytics.sdk.android:crashlytics:2.6.0@aar') {
        transitive = true;
    }
}

目前我正在使用 Android Studio 版本 1.5.1（也尝试过 2.1，但没有成功。）我搜索了很多 google，但找不到确切的解决方案。

请帮忙。

谢谢。

Answer 1

经过长时间的努力，我找到了解决方法。

实际上问题专家 url : https://maven.fabric.io/public/io/fabric/tools/gradle/maven-metadata.xml

正在重定向到以下 url ： https://s3.amazonaws.com/fabric-artifacts/public/io/fabric/tools/gradle/maven-metadata.xml

不知何故，在 Android 工作室中，此重定向失败了。所以在 app build.gradle 文件中，我替换了 maven url。来自

  maven { url 'https://maven.fabric.io/public' }

到

 maven { url 'http://s3.amazonaws.com/fabric-artifacts/public' }

这解决了我的问题。
