The .classpath files must not contain a reference to a workspace project, because a different version might be in use. So generating them with the aggregator is a no-go. I somewhat like the idea of using M2 Eclipse plugin but there are two cons: 1. slow startup 2. dependency resolution is different versus Maven builds Especially the second item makes it unusable.
