For gradle-1.8 and gradle-1.9:

jtest3> ../gradle-1.9/bin/gradle -g $(pwd)/gradleHome build

This is on my todo list. No plans to support earlier versions. We accept pull requests if anybody wants to backport.

I think it is totally fine, if gradle-dependency-lock-plugin requires gradle >= 2.0. Just in that case, please document it clearly so that I don't have to experience the malfunction and then only after attempting to download a newer version during other debugging attempts discover that the gradle version is at fault.

Documented what versions we test against. Would release if anybody wanted to back port changes to an older version. Will accept pull requests to docs if anybody tests this against older versions.
