You can configure Mevenide through the 'Maven' Preferences page :
Window > Preferences > Maven. Preferences Pages
have been reorganized for better readibility.
Important pages are the Locations and Run pages. The later lets you specify
the size of the Heap (equivalent of MAVEN_OPTS=-Xmx...M) and a default goal to be run when
invoking the runner (thus allowing to support Eclipse one-click launching, whereas the
Locations page defines program Locations needed by Mevenide.
Those locations are automatically retrieved from relevant sources (e.g. system nvironment, build.properties, etc.)
at first execution, but can be then customized. Also they now can be regenerated using the 'Perform Defaults' button.
This page allows to define user defined dependency types. Those can then be used while editing
the POM though the POM editor or while synchronizing an Eclipse project through the POM Synchronizer.

The Templates preferences page is used to manage POM templates that are available to Mevenide. Please see Pom Templates description for more informations
Those preferences pages are dynamic and allow Maven plugin provider to contribute to Mevenide in a fairly simple way. Please refer to the Provider page description if you're interested in plugging into Mevenide.
