Redmine is one of the most popular Ruby on Rails applications which has made quite a name for itself in the world of Project Management. It offers a lot of flexibility. One of its main advantages is that it can recognize your files repository and can work along with your source control system to keep track of all changes through the tracker itself.
Here is one error that we came across when we tried to integrate our filesystem and source control management system with Redmine -
Error: The entry or revision was not found in the repository
Are you getting an error like this when trying to access the repository tab of Redmine even after you have set the correct path to the repository in the redmine settings? Then this is for you.
Check permissions of the repository folder. In a GNU/Linux system, the repository folder should be accessible by the webserver/redmine. To make it accessible to redmine, you have to either change the group of the folder to the group accessible by the webserver or give read only permission to others.
This should do the trick:
chmod o+rx repository_folder
