Force Gradle to use HTTP instead of HTTPS

I am trying to build react-native android app, as a dependecy I see I have gradle, but it fails to load on build.Error message:

* What went wrong:A problem occurred configuring root project 'MobileApp'.> Could not resolve all dependencies for configuration ':classpath'.> Could not resolve com.android.tools.build:gradle:1.3.1.     Required by:         :MobileApp:unspecified> Could not resolve com.android.tools.build:gradle:1.3.1.> Could not get resource 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.> Could not GET 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.> Connection to https://jcenter.bintray.com refused

The issue is clear, I am sitting behind corporate proxy that blocks any HTTPSconnections like these in error.So my questions are: how to force gradle to use HTTP in loading these files? Where these properties should be put(which of gradle files, i.e. gradle.properties)?

P.S. I already have set these in gradle properties file:

systemProp.http.proxyHost= myHostsystemProp.http.proxyPort= myPortsystemProp.http.proxyUser= myUsersystemProp.http.proxyPassword= myPassword

Any links, suggestions or etc. will help a lot.
