as报错

android studio报错
报错一：Could not HEAD 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.1.2/gradle-3.1.2.pom'. Received status code 400 from server: Bad Request Enable Gradle 'offline mode' and sync project
解决：1.repositories中加入aliyun maven
buildscript {
repositories {
maven {
url 'http://maven.aliyun.com/nexus/content/groups/public'
}
google()
jcenter()
}
2.设置-将代理设置中过滤掉maven.aliyun.com

报错二：Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:appcompat-v7:27.0.2. Open File
解决：上个问题在buildscript的仓库中加了aliyun maven，这次在allprojects中的仓库配置中也加入aliyun maven即可
allprojects {
repositories {
maven {
url 'http://maven.aliyun.com/nexus/content/groups/public'
}
google()
jcenter()
}
}
这2个配置都在项目级别的build.gradle配置中

报错三：Configuration on demand is not supported by the current version of the Android Gradle plugin since you are using Gradle version 4.6 or above. Suggestion: disable configuration on demand by setting org.gradle.configureondemand=false in your gradle.properties file or use a Gradle version less than 4.6.
解决：
No need to downgrade!
Disabling configure on demand requires two steps:
Remove org.gradle.configureondemand from gradle.properties.

In Android Studio,
For Mac go to the Preferences > Build, Execution, Deployment > Compiler and uncheck the configure on demand.
For Linux/Windows go to the File > Settings > Build, Execution, Deployment > Compiler and uncheck the configure on demand.

Note, there are 2 gradle.properties files

In your project gradle.properties
${HOME}/.gradle/gradle.properties
Hope this helps :D #HappyCoding
1.删除 org.gradle.configureondemand from gradle.properties
2.file-settings- Build, Execution, Deployment - Compiler 去掉勾选configure on demand
