404 Error when accessing tasks from Eclipse Luna - Redmine 3.0

[sselvia]

After I had upgraded to redline 3.0 I started getting 404 errors from the mylyn eclipse plugin when I accessed any of my tasks. This worked perfectly with redline 2.6.1.

Maybe this pull request could help you (for me works with Redmine 3.0.1 and Rails 4.2).

Thanks a lot David! I have a lot of people waiting for this.

I have same issue with a fresh git clone

I'm not really comfortable with ruby but it seems version are quite the same than david.
Any tips ?
