Jenkins + Multiple SCMs + git + hooks/triggers = mission Possible

Multiple SCMs plugin version 0.2 - in its documentation is remarked two controversial statements:

• "Post-commit type triggers don't currently work".
• "Allow polling to work with multiple instances" - in version 0.2

So is pooling possible? There are people on the internet stating the two opposite points. Yes, it is possible but some tricks are needed.

linux: demonizing a process and killing it when you want

This is very useful for processes which do not write an PID file. This is stupid... but it could be work-arounded.

For example I want to start ant kill later the jasmine server, which is started this way:
bundle exec rake jasmine:server --trace

magic apostrophes in linux = Back Quotes for Command Substitution

They are replaced by the output of the command between them:

kill -9 `echo 9999`

is equivalent to:

killing app, listening on a defined port in single line

In Linux this will kill the process, listening on port 8888:

ps aux | grep port=8888 | awk '{print $2}' | tail -n 1 | xargs kill -9
