Gradle distribution server does not accept http anymore

The gradle distribution server referenced in your gradle ebuild file does not accept http connections anymore.

mva-overlay/dev-java/gradle/gradle-5.3.1.ebuild

Line 9 in 94e6148

 SRC_URI="http://services.gradle.org/distributions/${P}-src.zip"
