Why is gradle downloaded in every project that I run using new ionic?

Since yesterday, whenever I run ionic run android, it’s downloading gradle in every project - can this be made as a global installation? or if it’s required by every android project, why is it not added while adding android platform?

build.gradle -PcdvBuildArch=arm -Dorg.gradle.daemon=true
