I want to try out this websocket implementation: https://jwebsocket.org/documentation/installation-guide/eclipse
The project is provided with maven. Thus I want to install the m2eclipse plugin as suggested on their site.
The problem is that the provided link does not work: http://m2eclipse.sonatype.org/sites/m2e
I also tried this one: http://eclipse.org/m2e/download/
Both are not working. Can someone give me a hint how to install this plugin?
That information is outdated, referring to Eclipse 3.3 and 3.5.
Maven integration is part of Eclipse itself now. If you download a current Eclipse bundle it can be part of it. http://www.eclipse.org/downloads/compare.php?release=kepler
If you downloaded the "classic" version go to Help > Install New Software, select the update site for your version (should be "Kepler") and select the Maven integration via filter or category ("Collaboration").
