Eclipse builders

When creating builder as in every other extension point make sure that IDs of builder and IDs in extension point match up. Otherwise your builders will not work and you will not know what went wrong. One place to check is project properties (right-click project -> properties -> Builders. If your build is listed as "Missing Builder" then chances are IDs are screwed up.

EMF Ecore model inheritance

Let's say you have a common.ecore with Node element. You create person.ecore in another plugin and want Person->Node inheritance. To do this create your person.ecore and load common.ecore from "Sample Ecore Editor" menu. Continue creating Person element and setting super type as node. Now, when it's time generate genmodel for person.ecore on package selection page of wizard you will see packages for person and common. Make sure you don't select common checkbox and instead choose common.ecore from "Reference generator models" pane. If you don't then person model will expect common to be on the same level as itself and you don't want that.
