Redmine importer does not handle Redmine groups properly

[Martin Burger]

I tried to import all issues from a Redmine installation. The installation uses a group to assign issues to that group. The import process failed with the following error:

2013-01-08 12:10:01,180 ERROR - Unexpected failure occurred. Importer will stop immediately. Data maybe in an unstable state

The importer requested /users/8.json?include=memberships which does not exist:

x.x.x.x - - [08/Jan/2013:12:10:01 +0100] "GET /users/8.json?include=memberships HTTP/1.1" 404 616 "-" "-"

Redmine user with id 8 is not an actual user, but the above-mentioned group. Therefore, the above request fails (not found). As a workaround, I created a new dummy user with id 12, that does not belong to any group or project, and set up the following redirect:

RewriteRule ^users/8\.json /users/12.json [L,R]

That way, the importer got the return value for user with id 12 instead. I assume this is a bug in the Redmine importer plugin, isn't it?

Hi Martin,

1. Redmine importer supports version 1.3 and above and 2.0 and above. So it supports version 1.4

2. The behavior described in your question is definitively a bug. I've raised a bug report for it https://ecosystem.atlassian.net/browse/JIM-915

[Immanuel Siagian]

The above stack-trace seems to be related to the incompatibility of the Redmine version. Please make sure that the Redmine version is 1.3+ or 2.0+.

[Martin Burger]

It was Redmine 1.4.1.stable.9615.

[Martin Burger]

Wait a minute - does this mean that the Redmine importer supports 1.3 but does not support 1.4?
