我是Gradle的新手,我正在阅读文档,但我不了解它的某些部分.其中一个部分与buildscript块连接.它的目的是什么？

如果构建脚本需要使用外部库,则可以将它们添加到构建脚本本身的脚本类路径中.您可以使用buildscript()方法执行此操作,并传入一个声明构建脚本类路径的闭包.

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath group: 'commons-codec', name: 'commons-codec', version: '1.2'
  }
}

好的但是有什么区别:

repositories {
  mavenCentral()
}
dependencies {
  compile group: 'commons-codec', name: 'commons-codec', version: '1.2'
}

例如,为什么有必要使用buildscript？

buildScript在gradle构建部分或构建的根级别中声明存储库之间有什么区别.

选项1:

build.gradle:

buildScript {
    repositories {
        mavenCentral();
    }
}

要么

build.gradle:

repositories {
    mavenCentral();
}

我将gradle插件更新为最新版本:com.android.tools.build:gradle:3.0.0-alpha1 发生此错误:

export TERM="dumb"
if [ -e ./gradlew ]; then ./gradlew test;else gradle test;fi

FAILURE: Build failed with an exception.

What went wrong:
    A problem occurred configuring root project 'Android-app'. Could not
 resolve all dependencies for configuration ':classpath'. Could not
 find com.android.tools.build:gradle:3.0.0-alpha1. Searched in the
 following locations:

我在我的项目中尝试谷歌分析.但在更改build.gradle文件后发现以下错误消息.

错误:找不到com.google.gms:google-services:2.0.0-alpha6.在以下位置搜索:file:/home/vaibhav/android-studio/gradle/m2repository/com/google/gms/google-services/2.0.0-alpha6/google-services-2.0.0-alpha6.pom文件: /home/vaibhav/android-studio/gradle/m2repository/com/google/gms/google-services/2.0.0-alpha6/google-services-2.0.0-alpha6.jar https://repo1.maven.org/ maven2/com/google/gms/google-services/2.0.0-alpha6/google-services-2.0.0-alpha6.pom https://repo1.maven.org/maven2/com/google/gms/google-services /2.0.0-alpha6/google-services-2.0.0-alpha6.jar 要求:: MaterialTabs-master:未指定

我在哪里1.将依赖项添加到项目级build.gradle:

classpath'com.google.gms:google-services:2.0.0-alpha6'

2.将插件添加到您的应用级build.gradle:

申请插件:'com.google.gms.google-services'

和

3. 为Google Play服务添加依赖项.在build.gradle里面添加:

编译'com.google.android.gms:play-services-analytics:8.4.0'

提前致谢.
