ccranford,
Looks like you’ve installed the m2e-apt plug-in and MyEclipse has detected an update for it, to version 1.1. That version requires m2e 1.4 but MyEclipse 2014 maven support is based on m2e 1.4, so you will not be able to install or update m2e-apt 1.1 on our 2014 release. Our latest release, 2015, updates the maven eclipse support to 1.5 so you should be able to install m2e-apt 1.1 on MyEclipse 2015. You can download 2015 from here. your current subscription can be used for all releases of MyEclipse while it is valid. MyEclipse 2015 may be installed alongside 2014, if you wish.
If you can’t make use of release 2015 yet, I’m afraid that, looking at the m2e-apt requirements information you won’t be able to upgrade to m2e-apt 1.1.
Sorry for the inconvenience.
