Solution 1

First create pom.xml files in all projects, then:

Old school:

Run mvn eclipse:eclipse, switch to eclipse and do Import > Existing Projects

New School:

Install m2e, don't run eclipse:eclipse (because it has no effect on m2e) and do Import > Maven > Existing Maven Projects

Don't mix the two, they are not compatible with each other.

You have to configure the pom.xml of the child project ("D"). You need to insert the tag with the follow configuration: groupId, artifactId and version.

And into the parent's pom.xml you need to add the new module child ( tag).

e.g. D pom.xml

<parent>
    <groupId>com.project.A</groupId>
    <artifactId>A</artifactId>
    <version>1.0.0</version>
</parent>

A pom.xml

<modules>
    <module>D</module> --> It is the artifact Id
    <module>...</module>
    <module>...</module>
</modules>
