问题一:Could not resolve all artifacts for configuration ‘:fluwx:classpath’

A problem occurred configuring project ':fluwx'.

  • 第一步:修改掉项目下的android目录下的build.gradle文件,把google() 和 jcenter()这两行去掉。改为阿里的链接。
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' }

  • 第二步:修改Flutter SDK包下的flutter.gradle文件,这个目录要根据你的SDK存放的位置有所变化。比如我放在了这个路径
    /Users/lc/flutter/packages/flutter_tools/gradle/flutter.gradle
    打开文件进行修改,修改代码如下(其实也是换成阿里的路径就可以了)。
  • 如果还是解决不了,只能试试了

问题二:Exception in thread “main” java.net.UnknownHostException: services.gradle.org

Exception in thread "main" java.net.UnknownHostException: services.gradle.org

在Mac运行web项目的时候,出现主机IP找不到的问题。主要是因为在Mac中主机名和window有所区别
一、输入命令

cat /private/etc/hosts

二、输入命令

sudo vi /private/etc/hosts

三、进入VI编辑器,增加如下的映射

127.0.0.1 xxxxxxxxx

四、最后,在终端中输入刷新的命令

dscacheutil -flushcache

问题三: Error:Execution failed for task ‘:app:mergeDebugResources’.

问题四:GradleException显示红色报错解决办法

throw new GradleException(...)
替换
throw new Exception(...)
