Add an API project (e.g. VaultAPI) so I don't have to worry about the dependencies. For example I have to manually “mvn install” PermissionsEx. But with an API which don't need any dependencies (maybe Bukkit) it would be smaller and easier to install.

what are you talking about? the pom provided with Vault handles it already, in addition, Vault has a repository on jenkins, you should NEVER need to manually build it. So I'm kind of lost as to what you're asking me to do here with Vault that requires the interfaces be seperate from Vault itself.
