Importing Epics, Epic Links and linked tickets cannot be done using single CSV file

Issue Summary

Importing Epics, Epic Links and linked tickets cannot be done using single CSV file. Two or more CSVs are required to import new issues and Epics and to link them.

Steps to Reproduce

1. Prepare a CSV file that contains new Epics, new or existing issues and Epic Links to link those two
2. Import the data using Importer functionality

Expected Results

Epics and corresponding issues are created and linked from the same CSV file.

Actual Results

Links are not created after the import.

The below exception is thrown in the atlassian-jira.log file:

2016-05-25 19:17:57,822 WARN - Cannot add value [ [My Epic] ] to CustomField Epic Link in Issue with summary 'Story in Epic'. Probably value was in incorrect format

Workaround

The workaround is described on the knowledge article Cannot Import Epic Link from CSV due to Incorrect Format.

The idea is to:

• Use one CSV file to import new Epics and issues
• Use the second CSV file to import links between Epics and issues.
