Android Studio 3.0.1 gradle build pkix pathbuilding failed

Solved this by adding the self signed certificate of my company to the cacerts file of Android Studio. The cacerts file is located here: C:\Program Files\Android\Android Studio\jre\jre\lib\security\cacerts

I have also added the proxy details for http/https to gradle.properties.

Yeah, I have resolved the issue by changing the WiFi network connection. do any of the following step 1. connect to other or Mobile network(use hotspot) and reconnect to WiFi network 2. Reset your wifi network in laptop
