github2jira
A simple ruby script to port github issues into CSV format compatible with Jira importer.
Usage
I usually do this from irb - change the required username and password values (look for instances of github_username and github_password) and do the following:
require 'export_issues' ExportIssues.get_issues(from, to)
Where from and to represent the range of issues you want to retrieve. The retrieved values (along with comments) are saved by default to a file called ghissues.csv
WARNING: Jira CSV importer has a habit of choking on the hash character (#) in weird places. Either escape the char or replace it with something like "No. of XYZ" instead of "# of XYZ".
