eclipse: No "Maven" entry for Windows / Preferences

I had eclipse Juno running; I decided to upgrade to eclipse Kepler. I only had Java 1.6, so I downloaded and installed java 1.7, and changed my JAVA_HOME. I downloaded and unpacked Kepler and pointed it at my existing workspace.

I have two questions; First, when I click on "Window / Preferences", there is no entry for "Maven" on the left of the dialog. I shut down and rebooted the machine after I changed JAVA_HOME to ensure that didn't cause this.

I checked the list of installed plugins, and it lists m2e (v1.4).

Second, I am getting an error message "Plugin execution not covered by lifecycle configuration". There are a double-handful of sites indicating what to do about this, including the m2e's wiki pages, but over half the suggestions don't look reasonable, the wiki doesn't spell out what to do for its recommended solution, assuming you know, and the one that looked most promising to me involves using "Windows / Preferences / Maven".

So I'm most interested in the answer to the first question; if you have hints to offer on the second, I'm all ears...

I believe this came about by installing a new version of eclipse but pointing it at a workspace for the previous version. I have been told that there is metadata attached to a workspace that has to do with plugins; this would be bound to cause problems for a version that didn't have the plugins. I eliminated the new install, installed it again, created a new workspace, and imported-with-copy the project I wanted, that has eliminated the error. I will pursue that further.

Thanks to Adam Arold who pointed out the metadata issue.

Here are the things you can try:

  • Start Eclipse with the -clean switch
  • Uninstall / reinstall the plugin
  • Delete the plugin's files physically from the plugins folder and install it again from the Marketplace

If all else fails you can just get a fresh installation of Eclipse and reinstall your old plugins manually. There are some of them which won't work in a newer version of Eclipse (I remember for example that I had to install WindowBuilder all over again after an Eclipse version switch).
