执行教程中的 cap write_permissions 任务时出现 NullPointerException
NullPointerException while executing cap write_permissions task from tutorial
我在尝试从 Capistrano website 执行 check_write_permissions 任务时看到 NPE。
阶段文件本身很简单：
server "demo.ourapp.com", user: "deployuser", roles: %w{app db web}
set :branch, "dev"
set :deployment, "demo"
set :rails_env, "production"
role :app, "demo.ourapp.com"
role :web, "demo.ourapp.com"
role :db, "demo.ourapp.com", :primary => true
set :repository, "git@github.com:ouruser/ourapp.git"
set :deploy_to, "/opt/companyname/ourapp-demo"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log, "#{release_path}/log/puma.access.log"
set :puma_preload_app, true
set :puma_worker_timeout, nil
执行 bundle exec cap deploy this:stage check_write_permissions 后，出现以下错误：
$ bundle exec cap this:stage check_write_permissions --trace ‹jruby-9.1.12.0›

Tasks: TOP => check_write_permissions
我正在使用 JRuby 9.1.12.0、Capistrano 3.8.2。我已将信息匿名化，但 deployuser 确实具有无密码 SSH 访问权限。
非常感谢任何帮助。
搜索 org.jruby.ext.openssl.PKeyEC$Point.initialize(PKeyEC.java:845) 出现了这个：https://github.com/jruby/jruby-openssl/issues/105 这表明这是一个解决方法：
Net::SSH::Transport::Algorithms::ALGORITHMS.values.each { |algs| algs.reject! { |a| a =~ /^ecd(sa|h)-sha2/ } }
Net::SSH::KnownHosts::SUPPORTED_TYPE.reject! { |t| t =~ /^ecd(sa|h)-sha2/ }
这有什么帮助吗？
我在尝试从 Capistrano website 执行 check_write_permissions 任务时看到 NPE。
阶段文件本身很简单：
server "demo.ourapp.com", user: "deployuser", roles: %w{app db web}
set :branch, "dev"
set :deployment, "demo"
set :rails_env, "production"
role :app, "demo.ourapp.com"
role :web, "demo.ourapp.com"
role :db, "demo.ourapp.com", :primary => true
set :repository, "git@github.com:ouruser/ourapp.git"
set :deploy_to, "/opt/companyname/ourapp-demo"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log, "#{release_path}/log/puma.access.log"
set :puma_preload_app, true
set :puma_worker_timeout, nil
执行 bundle exec cap deploy this:stage check_write_permissions 后，出现以下错误：
$ bundle exec cap this:stage check_write_permissions --trace ‹jruby-9.1.12.0›

我正在使用 JRuby 9.1.12.0、Capistrano 3.8.2。我已将信息匿名化，但 deployuser 确实具有无密码 SSH 访问权限。
非常感谢任何帮助。
搜索 org.jruby.ext.openssl.PKeyEC$Point.initialize(PKeyEC.java:845) 出现了这个：https://github.com/jruby/jruby-openssl/issues/105 这表明这是一个解决方法：
Net::SSH::Transport::Algorithms::ALGORITHMS.values.each { |algs| algs.reject! { |a| a =~ /^ecd(sa|h)-sha2/ } }
Net::SSH::KnownHosts::SUPPORTED_TYPE.reject! { |t| t =~ /^ecd(sa|h)-sha2/ }
这有什么帮助吗？
