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.

Hi Sean, Okay let's say i have project "D" which is pure eclipse java project. I right-click > enable dependency management > it create POM.xml file. My problem is, I want make project "D" as child project of parent project "A". Project "A" contain packaging type "POM". I attempt another way also, after i turn my existing project "D" into mavan java project. I delete project (not physical location) and then, i Import > Maven > Existing Maven Project. However it does not make linked. Any suggestion

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>

Install Maven Plugin for Eclipse (m2e). Then in your project (command line), at the root level type mvn eclipse:eclipse. Reimport the generated project in Eclipse (Import Existing Projects into Workspace) and you should be all set.

That's nonsense. Use either m2e, or eclipse:eclipse, but not both.
