maven shows up some modules marked as "unnamed"

Question

I'm working with maven in a multi module project and it works fine. But when it starts it refers to some projects as unnamed. Why does this happen, and how can I solve it?

Answer 1

In every sub module, simply specify a <name>:

<project>
    ...
    <name>My project</name>
    ...

This name will then be used by the Reactor to display the build order of the modules.
