Redmine Cron Job Issue - cron

Question

I must set a Cron Job on Redmine to automatically manage IMAP fetching. I try to supply as many infos as I can about my environment:
Redmine version 3.2.0.stable
Ruby version 2.1.5-p273 (2014-11-13) [x86_64-linux-gnu]
Rails version 4.2.5
Environment production
Database adapter Mysql2
I have installed luismaia/redmine_email_fetcher as a plugin, and I have configured it for gmail IMAP. Up to this point I had no error messages and, by trying a test tool on Redmine, I get a success message.
I sum up the plugin configuration on Redmine as it follows:
Configuration type: IMAP
Is configuration active? true
Host : imap.gmail.com
Port: 993
SSL? yes
Email username: mailAddress
Password: mailAccountPwd
Folder Name: Inbox
Method for unknown users: accept
Now, I must run a Cron Job. At this link:
https://github.com/luismaia/redmine_email_fetcher
I have found the following:
*/5 * * * * www-data /usr/bin/rake -f /opt/redmine/Rakefile --silent redmine:plugins:email_fetcher:fetch_all_emails RAILS_ENV=production 2>&- 1>&
that I personalize as it follows:
*/5 * * * * www-data /usr/bin/rake -f /opt/redmine/Rakefile --silent redmine:plugins:email_fetcher:fetch_all_emails RAILS_ENV=production host=imap.gmail.com username=mailAddress password= mailAccountPwd port=993 --trace
Coming to the point: the line above doesn't work; and I've no idea why.
I can add that:
in /usr/bin I see rake2.1
opt directory (/var/opt) is empty.
I do hope I have explained my issue in a decent way.
Thank you in advance, really.
ps:
I tried also:
*/5 * * * * www-data /usr/bin/rake2.1 -f /var/www/redmine/Rakefile redmine:plugins:email_fetcher:fetch_all_emails RAILS_ENV=production 2>&- 1>&-
but nothing happens.

Answer 1

Test the which command:
which rake
for me it's in /usr/local/bin and not in /usr/bin
Next try to chdir in your redmine folder before launch the command in the crontab:
*/5 * * * * cd /var/www/redmine/ && sudo /usr/local/bin/rake redmine:plugins:email_fetcher:fetch_all_emails RAILS_ENV=production 2>&- 1>&-
Hope this can help you.
Cheers,
