We are moving from another issue tracking platform to Jira. How could i set up scripts that do issue state transitions automatically without having to log into Jira? Should i setup custom services?
Another case is when someone pushes code to mercurial. how could i setup automatic issue transitions on this event("development finished")?
I have Jira Atlassian,Fisheye, Mercurial up and running.
For the automatic issue transition, check out the script runner https://plugins.atlassian.com/plugins/com.onresolve.jira.groovy.groovyrunner
There are plenty of examples and built-in scripts allowing to implement this type of functionality (and much more)
For your second question, you can use the 'smart commit' feature provided by fisheye http://confluence.atlassian.com/display/FISHEYE/Using+Smart+Commits
It works ok with svn, not sure about hg.
