报错详情

解决方法(本地尝试可行):

  项目结构

  1.通过配置文件 gradle-wrapper.properties 查看项目所需的gradlew版本(上图所示为 gradle-5.6.2-all.zip)。通过浏览器下载到本地解压,将压缩包放入到与配置文件gradle-wrapper.properties同级目录下。入上图所示,我下载的是:

gradle-5.6.2-bin.zip

  2.修改gradlw.bat文件,在 APP_HOME下面添加一行代码,指定到gradlew目录(根据个人目录配置):/Library/profiles/gradle-5.6.2/.gradle

 

set APP_BASE_NAME=%~n0
set APP_HOME=%DIRNAME%
set GRADLE_OPTS="-Dgradle.user.home=/Library/profiles/gradle-5.6.2/.gradle"
set GRADLE_OPTS="-Dgradle.user.home=/Library/profiles/gradle-5.6.2/.gradle"

  3.修改 Flutter sdk中的gradle工具配置文件(根据自己的路径配置) : /Library/profiles/Flutter/sdk/flutter/packages/flutter_tools/gradle/flutter.gradle,添加国内的仓库镜像地址,指定到aliyun上:

buildscript {
    repositories {
        // google()
        // jcenter()
        maven { url ‘https://maven.aliyun.com/repository/google‘}
        maven { url ‘https://maven.aliyun.com/repository/jcenter‘}
        maven { url ‘http://maven.aliyun.com/nexus/content/groups/public‘}
    }
    dependencies {
        classpath ‘com.android.tools.build:gradle:3.5.0‘
    }
}
......
......
......
......

  4.重新启动运行,正常:
