How can I export Jira issues to BitBucket

Ive just moved my projects code from java.net to BitBucket. But my jira issue tracking is still hosted on java.net, although BitBucket does have some options for linking to an external issue tracker I don't think I can use it for java.net, not least because I do not have the admin priviledges need to install the DVCS connector.

So I thought an alternative option would be to export and then import the issues into BitBucket issue tracker, is that possible ?

Progress so far So I tried following the steps in both informative answers using OSX below but I hit a problem - I'm rather confused about what the script would actually be called because in the answers it talks about export.py but no such script exists with that name so I renamed the one I downloaded.

  • sudo easy_install pip (OSX)
  • pip install jira
  • pip install configparser
  • easy_install -U setuptools
  • Go to https://bitbucket.org/reece/rcore, select downloads tab, download zip and unzip, and rename to reece ( for some reason git clone https://bitbucket.org/reece/rcore fails with error)
  • cd reece/rcore
  • Save script as export.py in rcore subfolder
  • Replace iteritems with items in import.py
  • Replace iteritems with types/immutabledict.py
  • Create .config in rcore folder

  • Create .config/jira-issues-move-to-bitbucket.conf containing

    jira-username=paultaylor

    jira-hostname=https://java.net/jira/browse/JAUDIOTAGGER

    jira-password=password

  • Run python export.py --jira-project jaudiotagger

gives

macbook:rcore paul$ python export.py --jira-project jaudiotagger
Traceback (most recent call last):
  File "export.py", line 24, in <module>
    import configparser
ImportError: No module named configparser
- Run python export.py --jira-project jaudiotagger

I need to run pip insdtall as root so did

  • sudo pip install configparser

and that worked

but now

  • python export.py --jira.project jaudiotagger

gives

File "export.py" line 35, in <module?
  from jira.client import JIRA
ImportError: No module named jira.client

You can import issues into BitBucket, they just need to be in the appropriate format. Fortunately, Reece Hart has already written a Python script to connect to a Jira instance and export the issues.

To get the script to run I had to install the Jira Python package as well as the latest version of rcore (if you use pip you get an incompatible previous version, so you have to get the source). I also had to replace all instances of iteritems with items in the script and in rcore/types/immutabledict.py to make it work with Python 3. You will also need to fill in the dictionaries (priority_map, person_map, etc) with the values your project uses. Finally, you need a config file to exist with the connection info (see comments at the top of the script).

The basic command line usage is export.py --jira-project <project>

Once you've got the data exported, see the instructions for importing issues to BitBucket

#!/usr/bin/env python
