Snapcraft falha: [Errno 21] É um diretório: '/ caminho / para / snap / prime /.'

Question

Estou tentando fazer um projeto , que já provou ser um grande desafio. Eu tive que escrever nada menos que 3 plugins customizados, mas neste momento todas as partes terminam o staging. Depois de testar tudo, o snapcraft falha com o erro no tópico.

Aqui está o meu snapcraft.yaml:

name: stakeweightedvoting-app
version: "0.1"
summary: A blockchain-based secure voting and polling application
description: Stake Weighted Voting is Follow My Vote's application for stake-weighted voting on a blockchain. The app allows users to create and vote on polls on a blockchain, and securely tallying and displaying the results to ensure that no fraud can occur undetected.
confinement: devmode

apps:
  VotingApp:
    # If this actually works, I'll eat my hat. Can't fix it until I can build a snap, though...
    command: . $SNAP/opt/qt57/bin/qt57-env.sh && VotingApp

parts:
  stakeweightedvoting:
    plugin: x-qbs
    source: git://github.com/followmyvote/stakeweightedvoting
    source-branch: master
    build-packages: [qt57base, qt57declarative, qt57charts-no-lgpl, qt57quickcontrols2, qt57websockets, qt57svg, python-yaml]
    after: [botan, capnproto]
  capnproto:
    plugin: x-nonbroken-cmake
    source: git://github.com/sandstorm-io/capnproto
    # Ideally I would specify v0.5.3 here, but it no longer builds without tweaking, and I don't know how to apply patches in snapcraft
    source-branch: master
    source-subdir: c++
  botan:
    plugin: x-botan
    source: http://botan.randombit.net/releases/Botan-1.11.31.tgz

[Errno 21] Is a directory: '/home/dev/swv/prime/.'

Eu posso fornecer as fontes para os três plug-ins personalizados, mas nenhum deles substitui nada após a etapa de criação, por isso estou omitindo-os por enquanto.

Eu encontrei este bug que é provavelmente o que estou vendo, mas a solução não funcionou para mim.

command: . $SNAP/opt/qt57/bin/qt57-env.sh && VotingApp não funcionaria, pois é necessário fornecer um arquivo real no diretório snap e . é o resultado do erro que você recebe.

No entanto, você pode escrever seu próprio script de wrapper:

#!/bin/sh

source $SNAP/opt/qt57/bin/qt57-env.sh

exec VotingApp $*

e tem isso como a entrada command .

Faça algo semelhante à demonstração do tomcat com wrapper (mas você não precisa de um Makefile , basta usar o dump plugin 'como mostrado na demo do mosquito )
