Eclipse can't open sub-project of maven-parent-project

I have the following project structure:

pom.xml (packaging: pom)
\-- SubProject
  - pom.xml (packaging: jar)
\-- SubProject
  - pom.xml (packaging: ear)

I want to open all three projects in Eclipse.

When I select 'import existing project' it only displays the parent pom.xml (packaging: pom) but not the SubProjects.

(The projects have src, test, etc. and open just fine in Netbeans.)

When I move the parent pom to a subfolder and reference it by <relativePath>, eclipse can open it, but maven warns. So I'd rather not use this.

How can I open the proper Maven project structure in Eclipse?

you have to name the subprojects explicitly in the main POM modules section.

otherwise you have to navigate into the respective subproject folder when importing the subprojects.

The Eclipse "Import - Maven - Existing Maven Projects" on the parent folder should create two project folder in the eclipse workspace (on the same level).

It works with poms similar to:

Parent

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>parent</groupId>
  <artifactId>test.parent</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>pom</packaging>
  <modules>
    <module>mod1</module>
  </modules>
</project>

Module

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>parent</groupId>
    <artifactId>test.parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
  </parent>
  <artifactId>mod1</artifactId>
</project>

Nesting the folder in the Eclipse tree is not required (and cleaner).

If you chose "Import existing project into workspace":

After opening the parent project in eclipse, you see the folders with the sub-projects. You can right-click them and select "Import as project" from the context menu.

But you should use the solution of RobE if possible.
