When trying to download JIRA source code from https://my.atlassian.com/download/source/jira, some of the plugin sources are missing from the dependencySources subdirectory. For example:
The old url, https://my.atlassian.com/download/source/jira automatically redirects you to the JIRA Software source (https://my.atlassian.com/download/source/jira-software) which does not currently include the JIRA Core sources in their distribution. An issue has been created for this: https://jira.atlassian.com/browse/JSW-13315
