Maven Central now supports access via HTTPS. Gradle should, by default, access Maven Central over https (as opposed to HTTP as it does today). Please see http://central.sonatype.org/articles/2014/Aug/03/https-support-launching-now/ for the announcement and details. The only change necessary is to change “http://repo1.maven.org” to “https://repo1.maven.org”
we have that on the todo list. we already moved the defaults for jcenter to use https which is a superset of mavencentral.
We’ve made this change for 2.1.
