I set up mantis connect today on our server…
it was very easy: just drop the “mc” directory from the archive (and it’s subdirectory) to the Mantis root directory.
do not use the distribution from http://sourceforge.net/projects/mantisconnect as it does not work.
To test if MantisConnect works, you should be able to issue this command in a browser. It will pull up a list of all the SOAP commands supported:
http://domain.com/path_to_mantis/mc/mantisconnect.php
Instead, use the downloads on: http://sourceforge.net/project/showfiles.php?group_id=189858
a wiki is available at:
http://mylyn-mantis.wiki.sourceforge.net/
Then to get the client plugin working, use the eclipse update site: http://www.digital-d.at/eclipse/update
Note: You must have mylyn working first.
