安装及环境搭建

  1. 构建Android项目时，卡在Running Gradle task ‘assembleDebug’的解决方法:

打开Flutter SDK的安装目录, 找到Flutter的配置文件
文件路径为: Flutter安装目录/packages/flutter_tools/gradle/flutter.gradle
将repositories里的google()和jcenter()注释掉, 换成阿里仓库的maven地址

  1. buildscript {
  2.   repositories {
  3.     // google()
  4.     // jcenter()
  6.     // 添加
  7.     maven { url 'https://maven.aliyun.com/repository/google' }
  8.     maven { url 'https://maven.aliyun.com/repository/jcenter' }
  9.     maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
  10.   }
  12.   dependencies {
  13.     classpath 'com.android.tools.build:gradle:3.5.0'
  14.   }
  15. }
  1. 打开Flutter项目中的android/build.gradle文件, 跟步骤1一样, 将google()和jcenter()注释, 换成阿里maven仓库:
    1. buildscript {
    2. ext.kotlin_version = '1.3.50'
    3. repositories {
    4.  // google()
    5.  // jcenter()
    6.  maven { url 'https://maven.aliyun.com/repository/google' }  
    7.  maven { url 'https://maven.aliyun.com/repository/jcenter' }  
    8.  maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }  
    9.  }
    10. dependencies {
    11.  classpath 'com.android.tools.build:gradle:3.5.0'
    12.  classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    13. }
    14. }
    15. allprojects {
    16. repositories {
    17.  // google()
    18.  // jcenter()
    19.  maven { url 'https://maven.aliyun.com/repository/google' }  
    20.  maven { url 'https://maven.aliyun.com/repository/jcenter' }  
    21.  maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }  
    22. }
    23. }
