Android Studio 3.1: Proxy configuration: Unable to

Question

I recently upgraded my Android Studio from 3.0 to 3.1. In 3.0, I used to set proxy configuration in gradle.properties(Global properties) file, which includes setting systemProp.https.proxyPassword among others. However, I am unable to set this variable in 3.1. It seems like a design decision to prevent writing user password in an user-accessible file. However, how to go about setting the same?

Currently, whenever I set systemProp.https.proxyPassword, it gets overwritten with blank field next time I open Android Studio. And even after setting this variable again in gradle.properties (with global scope), I am unable to do git pull/push operations. It returns the following error:

Update canceled
Fetch failed: unable to access 'https://github.com/user_name/repo_name.git/': Received HTTP code 407 from proxy after CONNECT

Answer 1

C:\Users\Admin.gradle\gradle.properties open this file in your notepad and update your password both for
systemProp.http.proxyPassword=
systemProp.https.proxyPassword=

it worked for me !!!!

One solution which worked for me is the following.

1. Uncheck the box which says 'Require authentication' in the pop-up window which comes when you click on the proxy-error message. Note that the password section is 'N/A' in this pop-up message (i.e., there is option only to enter the username. It says you need to add the password in the gradle.properties file).

2. I set the following in gradle.properties (replace xxxx with your details)

   systemProp.https.proxyPort=xxxx
   systemProp.https.proxyUser=xxxx
   systemProp.https.proxyHost=xxxx
   systemProp.https.proxyPassword=xxxx
   systemProp.http.proxyPort=xxxx
   systemProp.http.proxyUser=xxxx
   systemProp.http.proxyPassword=xxxx
   systemProp.http.proxyHost=xxxx
   

3. Go to File -> Settings -> Appearance & Behavior -> System Settings -> HTTP Proxy. Enter your proxy details (with username and password here)

You can also write:

systemProp.https.proxyPort=xxxx
systemProp.https.proxyUser=xxxx
systemProp.https.proxyHost=xxxx
systemProp.https.proxyPassword=xxxx
systemProp.http.proxyPort=xxxx
systemProp.http.proxyUser=xxxx
systemProp.http.proxyPassword=xxxx
systemProp.http.proxyHost=xxxx

in %UserHome%/.gradle/gradle.properties Then, if Android studio ask you about proxy, just ignore it... It worked for me
