找不到 com.andorid.tools.build:gradle:3.0.0-beta2

Question

我无法解决与 gradle 文件关联的问题。为了解决这个问题，我下载了未构建项目的 android studio 3.0 beta 6。在 Android Studio 2.3.2 中，出现了以下问题

顶级等级

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta6'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.0'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2'
    }
}

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

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

刚刚添加了 google maven repo：

在取消注释 allproject 块之后

错误 如何解决这个问题？我在堆栈上看过很多解决方案，但无法解决这个问题

Answer 1

您还必须在 顶级 build.gradle 文件的 buildscript 块中添加 ma​​ven google：

buildscript {
    repositories {
       jcenter()
       ...
       // You need to add the following repository to download the
       // new plugin.
       maven { url "https://maven.google.com" }
    }
   dependencies {
       classpath 'com.android.tools.build:gradle:3.0.0-beta6'
       //...
   }
}

此版本的插件还需要更新版本的 gradle。您必须按如下方式更新gradle-wrapper.properties 中的distributionUrl：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

关于plugin 3.0.x here的更多信息。

Answer 2

repositories {
   jcenter()
   ...
   // You need to add the following repository to download the
   // new plugin.
   maven { url "https://maven.google.com" } //THIS
   google() //OR THIS
}

同时删除 .gradle 和 gradle 文件夹并重新同步项目。缓存问题

我已经通过使用 Android Studio 3.0 Beta2 解决了这个问题。我刚刚更改了gradle依赖项如下

顶级 gradle 依赖项

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.0'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.2.2'
    }
}

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

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

我刚刚将 beta6 更改为 beta2。我不知道它是如何工作的，但它工作正常
