Hey, I'm adding Sergio to the conversation, but I think the easiest path is to create a custom plugin, inheriting from the base java one, which is outputting a wrapper scripts with different JAVA env variables. That way, you keep the current building behavior (build with java on the machine), but output a script which will point to an armhf java path for instance and download the correct version and packages version for all those. Cross-compilation-like may be needed as Manik suggested as you will need to pull some packages which are architectures specific. On how to create a custom plugin, here is some documentation: http://snapcraft.io/docs/build-snaps/plugins and the playpen has some example: https://github.com/ubuntu/snappy-playpen/blob/master/idea/parts/plugins/x-antIntellij.py I'll let Sergio adding more info as needed :) Cheers, Didier > Jian > > > On Oct 10, 2016 20:05, "Manik Taneja" <ma...@canonical.com > <mailto:ma...@canonical.com>> wrote: > > > > On Mon, Oct 10, 2016 at 6:33 AM, Jian LUO <jian.luo...@gmail.com > <mailto:jian.luo...@gmail.com>> wrote: > > Hi List, > > Is there any formal way in snapcraft to set environment > variables separately for build time and run time?
