将Android Studio更新到最新版本(3.1)并在我的项目中使用gradle版本后,我收到错误(链接总是不同):

Android Studio版本:

Android Studio 3.1
Build #AI-173.4670197, built on March 22, 2018
JRE: 1.8.0_152-release-1024-b02 amd64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Windows 10 10.0

我已经尝试过干净重建和更新gradle,重新启动Android Studio和PC,但没有成功.有任何想法吗？

PS:我当然有互联网.此外,如果您在浏览器中打开一个链接 - 该文件已下载.

jcenter目前有问题,请查看http://status.bintray.com/

Answer 2

将Android Studio更新为3.1.0后,

我只是有同样的问题,我解决了它的使用

 maven {   url "https://maven.google.com"  }

在项目级gradle中像这样的TopMost : -buildScript

 buildscript {
    repositories {
      .....
      ...
     maven {   url "https://maven.google.com"   }

作为参考采取样本项目级的的gradle -

buildscript {

  repositories {
      google()
      jcenter()
      maven { url 'https://maven.fabric.io/public' }
      maven { url 'https://jitpack.io' }
      mavenCentral()
      maven { url 'https://maven.fabric.io/public' }
      maven {  url "https://maven.google.com"  }
  }
 dependencies {
     classpath 'com.android.tools.build:gradle:3.1.0'
     classpath 'io.fabric.tools:gradle:1.24.4'
   }
}

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

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

注意: - 还有一件事: -

在gradle-wrapper.properties使用中: -

  distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

相反的4.1-all.zip.

编辑: - 如果你想快速解决问题,你也可以尝试添加这些 - 根据奥马尔的答案: -

 maven { url "http://dl.bintray.com/riteshakya037/maven" }

随着

  maven { url "https://maven.google.com" }

提示：
当您正确构建项目时，请启用一次离线模式，这样 AS 就不必在每次 gradle 刷新时连接到 jcenter。

Answer 4

感谢大家的快速解答!

这似乎是"jcenter.bintray.com"网站上的临时网络问题.我只是多次点击"再试一次",最后一切都更新了.

此外,如果您在浏览器中打开链接 - 您将不时收到"服务错误"消息.所以问题不在你身边.

Answer 5

好的，我喜欢它：

在您的build.gradle项目级别中，添加以下内容：

buildscript {
    ...
repositories {
    google()
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
    maven { url 'https://jitpack.io' }
    mavenCentral()
    maven { url "https://maven.google.com" }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0' // Updated from 3.0 to 3.1.0

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

请注意，我已将gradle从 3.0更新为 3.1.0

下一步：将之前相同的链接添加到allprojects 的存储库正文：

allprojects {
repositories {
    google()
    jcenter()
    mavenCentral()
    maven { url 'https://jitpack.io' }
    maven { url "https://maven.google.com" }
    maven { url 'https://maven.fabric.io/public' }
}

}

还有一件事：

在gradle-wrapper.properties 中使用这个：

distributionUrl=https://services.gradle.org/distributions/gradle-4.4-all.zip

之后，只需再次同步，它就会起作用。
