flutter踩坑01:下载包失败:Could not resolve all artifacts for configuration....

flutter在下载依赖失败或者flutter run运行的时候出现某个jar或者文件下载失败的时候,如下:

FAILURE: Build failed with an exception.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

步骤1:更新项目的依赖

打开项目的 android/build.gradle文件,将里面的两个repositories改为

    repositories {
        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‘
        }
        google()
        jcenter()
    }

步骤2:将下载失败的包的依赖修改

A problem occurred configuring project ‘:url_launcher‘. 可以看出url_launcher下载依赖失败了;

• 打开flutter的sdk文件夹,进入/.pub-cache\hosted,里面的文件夹是各个镜像库,在mirrors.tuna.tsinghua.edu.cn文件夹(没有的话就是其他文件夹)中找到url_launcher;
• 进入里面的android/build.gradle文件,和上一步一样的替换两个repositories,这个依赖在下载依赖的时候,就会从阿里云的镜像库下载,就能下下来了.
