Is it possible to connect mylyn to redmine without rest support in redmine?
there is a link http://download.eclipse.org/mylyn/incubator/3.8 that can be used in Eclipse. for Eclipse indigo :
- Help -> Install New Software -> Add -> use the link above for URL
- there should be plugin to check off : Mylyn Incubator -> Mylyn Task Connector:Web Templates (Advanced)(Incubation). Version = 3.8.0.I20120414-0402
after installing it, i was able to follow steps outlined in http://www.redmine.org/projects/redmine/wiki/HowTo_Mylyn ( the section 'Using the generic web repository connector' ).
there is also a half decent video on Youtube :)
If you are using Eclipse indigo then use the update site:
(As of 09/16/2012) http://download.eclipse.org/mylyn/incubator/3.8
install "Mylyn Tasks Connector: Web Templates (Advanced)" and follow the instructions at the link mikalv posted above.
It looks like the incubator links is changing as Eclipse versions go up. It looks like the best way to find out the update url is to check Generic Web Templates Connector section of Mylyn User Guide wiki They provide the up to date link to mylyn download site where you can find the update url for the incubator.
