Reason for question: In order to include MCBEFormAPI, a submodule of this plugin, in a phar file built with Poggit. Question contents: Briefly, is there a way to include submodules in phar using poggit? If not included, is it wise to use Virion? Remarks: Just by adding a submodule to the repository, it was not added in the phar file...
Yes. Add a submodule: true line to .poggit.yml. See https://github.com/poggit/support/blob/master/poggit.yml.d.ts for all available options in .poggit.yml
