Hi, Thanks for the explanation. That's exactly what comes first in my mind. I've tried to customize the ant / jdk plugin by overriding the env method. The doc string of BasePlugin.env reads "return a list with the execution environment for building". However the result env applies both to build time and to the generated wrapper nonetheless. How can i override runtime only env in the plugin?

Just wanted to compile Java with one JDK and run with another. 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> wrote: > > > On Mon, Oct 10, 2016 at 6:33 AM, Jian LUO <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?
