Hey there! Let's break down how to group your two Maven projects (SomeSuperName1 and SomeSuperName2) in IntelliJ IDEA, since they both share that common parent POM structure. I'll cover two approaches—one that aligns with Maven's native aggregation, and another that's just IDE-level grouping if you don't want to modify your POMs.

This method creates a top-level POM that aggregates both projects, which is the "Maven-native" way to group modules and keeps your build configuration consistent.

1. Create a new aggregator project
   • Either create a new empty Maven project directly in IDEA, or make a new folder on your disk (e.g., myapp-aggregator) and add a pom.xml file to it.
2. Configure the aggregator POM
   Paste this into your new pom.xml—adjust the details to match your existing setup:

   <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>com.company.yeah.myapp</groupId>
       <artifactId>myapp-aggregator</artifactId>
       <version>1.0.0</version>
       <packaging>pom</packaging>
       <name>MyApp Aggregator</name>
   
       <!-- Add your two projects as sub-modules -->
       <modules>
           <module>../SomeSuperName1</module>
           <module>../SomeSuperName2</module>
       </modules>
   </project>
   

   Double-check that the <module> paths point correctly to your existing project folders relative to the aggregator's location.
3. Import the aggregator into IDEA
   Go to File > Open, select the aggregator's pom.xml, and choose "Open as Project". IDEA will automatically detect and import both SomeSuperName1 and SomeSuperName2 as submodules under the aggregator.

If you just want to organize the projects in IDEA without altering your Maven configuration, use this lightweight method:

1. Import both projects into IDEA
   • First, open SomeSuperName1 via File > Open.
   • Then, go to File > New > Module from Existing Sources, select SomeSuperName2's pom.xml, and follow the prompts to add it as a module to your current IDEA project.
2. Create a module group
   • Open the Project Structure window with the shortcut Ctrl+Alt+Shift+S (or via File > Project Structure).
   • Switch to the Modules tab.
   • Click the + button in the top-left corner, then select Module Group.
   • Name your group (e.g., MyAppProjects), then drag both SomeSuperName1 and SomeSuperName2 modules into this group.
3. View the grouped modules
   • Switch back to the Project view (make sure you're using the "Project" view mode, not "Packages" or "Project Files").
   • You'll see your new group with both projects nested under it—you can expand/collapse it as needed for easier navigation.

Quick Tips #

• For the aggregator approach: Ensure your shared parent POM (com.company.yeah:parent:1.0.0) is either installed in your local Maven repository (run mvn install on the parent project if it's not) or the relativePath in your projects points to it correctly.
• If you don't see the group in the Project view, right-click the group name and check Group Modules in the context menu to enable nested display.
