Answer 1

In my case, because my system configured to an http proxy, I found some below settings in gradle.properties(Global prperties). May be this file doesnt exist in all projects, but to display put your android studio root on Android. after remove mentioned settings (below) error solved.

systemProp.http.proxyHost=
systemProp.https.proxyHost=
systemProp.https.proxyPort=80
systemProp.http.proxyPort=80

Answer 2

If you're not using any proxies then:

1. Delete /project_directory/.gradle folder
2. Clean your project (Build -> Clean Project).
3. Sync project again

It should be working after these steps.

In my case I starting having this error after I updated:

Gradle plugin 3.6.3 -> 4.0.0
Gradle: 5.6.4 -> 6.1.1

First check your internet proxy settings copy the proxy settings like proxy host and port no. and go to your "gradle.properties" file in project and paste it like this

systemProp.http.proxyHost="copied proxy host"
systemProp.http.proxyPort="copied proxy port"

systemProp.https.proxyHost="copied proxy host"
systemProp.https.proxyPort="copied proxy port"

Generally people paste the system prop for http but forget for https so please paste both.

Sometimes, even you are not behind an http proxy, you need to configure them with dummy data like this:

systemProp.http.proxyHost=www.anyhost.com
systemProp.http.proxyPort=80
