If I leave Gradle home path empty, studio downloads Gradle anyway. Could you please clarify where have Gradle binaries been placed? What versions of gradle does Studio support?
Gradle binaries are usually deployed to ~/.gradle/wrapper/dists, but it is not controlled by Studio. Thus, it’s not documented.
We officially support Gradle 1.12 which is currently coming with the latest version of Studio. Versions 2.0 - 2.3 also work, but version 2.4 doesn’t because of some incompatibilities in the dependencies resolution mechanism.
