How do I set up a fully self-contained build of Cordova?

I created a test project in Cordova using cordova create hello com.example.hello HelloWorld ; cd hello ; cordova platform add android

.

The first time I build it with cordova build

it downloads Gradle and then I think it's a bunch of Maven files, almost 200 of them. They seem to be installed in ~/.gradle

, but I'm not sure if this is the only location. Output example:

$ cordova build
ANDROID_HOME=/opt/android
JAVA_HOME=/usr/lib/jvm/java-8-oracle/
Subproject Path: CordovaLib

Now this may be convenient, but completely undesirable in terms of having a reproducible build environment.

How do I configure Cordova for fully self-contained builds? Will it do offline builds after the first one, or is it still checking (for example) Gradle updates?

How (and where) do I pre-install whatever I'm looking for cordova build

? Is there a way to get Cordova to install everything as a separate step from building the build and make the build as a separate step from that install?

Is it possible to archive the content one day ~/.gradle/

and then unpack it before running a build (either on the same machine or on a different one) and run that build offline? How do I move ~/.gradle/

to (for example) a subdirectory of a Cordova project?
