How to have Capistrano NOT rollback if a task fails -

-

we're using capistrano/webistrano (with lee hambley's railsless-deploy gem) push our php application production servers. have custom tasks run during various parts of deploy process.

as example, have tasks attempt stop , restart jetty solr instance. however, bit fails during deploy, capistrano rolls entire deploy , reverts previous revision. pain. :-)

i'd tell capistrano ignore return result of these tasks, if fail, capistrano continues on it's way , finishes deploy anyway. it's easy me ssh server after fact , kill , restart solr instance, rather having complete deploy again.

here relevant parts of deploy script:

before "deploy:symlink", :solr_kill after "deploy:symlink", :solr_start, :solr_index  task :solr_kill     run "cd #{current_path}/base ; #{sudo} phing solr-kill" end  task :solr_start     run "cd #{current_path}/base ; #{sudo} phing solr-start"     run "sleep 10" end  task :solr_index     run "#{sudo} #{current_path}/base/bin/app.php cron run solr_index_cron" end

from capistrano task docs there config can add if there error, continue.

task :solr_start, :on_error => :continue     # code here end

just add each task want ignore errors , continue. though, best possible thing see if can figure out causing failure , have restart command more robust restart it. this, since when try hand off script else, might not know how tell if restarted correctly.
