insecure gradle

[IzzySoft]

just in case someone is still working on this project: F-Droid lint just complained about

build/ch.phcoder.jigit/build.gradle
repositories {
  mavenCentral()
  maven {
    url "http://repo.gradle.org/gradle/javascript-public"
  }
gradle build uses plain HTTP URLs for repositories!  This is insecure!

should be solved easily by changing the protocol to https (page responds fine).
