Redmine

Redmine 2 uses bundler, so you might be luckier with bundle exec redmine:plugins:hook_list instead. As an alternative, you could also just run grep -r call_hook * to show all source files that use hooks.

No, I was not luckier ...

D:\apps\redmine_svn>bundle exec redmine:plugins:hook_list
Unfortunately, a fatal error has occurred. Please see the Bundler

(See full trace by running task with --trace)

My bad, I missed the rake. The correct command should be bundle exec rake redmine:plugins:hook_list.

 bundle exec rake redmine:plugins:hook_list

Did you try grepping (as mentioned)? Assuming you are on Windows, you can download grep here: http://gnuwin32.sourceforge.net/packages/grep.htm. You can also just search for call_hook using your favorite IDE or possibly even Windows Explorer :)

As far as I know the redmine:plugins:hook_list rake task has been deleted in r9490 as part of Rails-3.2 work.
No substitution has been implemented afterwards so it will come down to solutions like grepping as Jan already pointed out.

Maybe it's worth opening a FR with a request to re-implement such rake task? Any opinions?

Edit: I'll update the note on Hooks_List.
