Question

Error :

Could not find com.android.tools.build:gradle:4.0.1. Searched in the following locations:

https://jcenter.bintray.com/com/android/tools/build/gradle/4.0.1/gradle-4.0.1.pom https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.0.1/gradle-4.0.1.pom

Required by: project : Open File

*** looks like google() and jcenter() are not working as expected.***

Answer 1

I think the solution will only work in Iran . If you know that 's working out of Iran , please note in the comments .

why would a proxy be necessary? There have been a number of technology-related sanctions against Iran.

go to -> File | Settings | Appearance & Behavior | System Settings | HTTP Proxy, and choose -> manual proxy configuration. set host name: fodev.org and set port number: 8118 . now you must find gradle.properties file. that must be in: Windows: C:\Users\YOURUSERNAME.gradle\gradle.properties OR for Linux: ~/.gradle/gradle.properties . if does't exist, create that yourself. and copy this :

systemProp.http.proxyHost=fodev.org
systemProp.http.proxyPort=8118
systemProp.http.nonProxyHosts=*.jitpack.io, *.maven.org
systemProp.https.proxyHost=fodev.org
systemProp.https.proxyPort=8118
systemProp.https.nonProxyHosts=*.jitpack.io, *.maven.org

now you can sync project.

IMPORTANT : after install build.gradle 4.0.1 (or every version), back this settings to before and remove codes
