I\'m trying out the next version of Eclipse using the latest milestone build and I\'m having an issue getting my Maven project deployed to Tomcat.
Previously in Ecli
It will work with the lastet version, it's just the .project that is not right.
Simply go into the project properties, make the projet faceted.. tick Dynamic Web Module and you'll get run on server as an option after that.

This will enable the "Run on Server" option, however your problems don't finish there as when you then run it, you'll get a 404.
To fix this, go back into project properties, Deployment assembly.

Delete the WebContent entry (and you can delete the folder in the project later too), and make sure you have the src-main-webapp & src-main-resource folders added.
Bingo.. run the app and it should be fine.
