Disable Module-Group view in Project view

Hello,

Could you please attach screenshot showing your project tree and screenshot from "File | Settings | Build, Execution, Deployment | Build Tools | Maven | Importing"?

Here are the screenshots

import with "Create module group for multi-module Maven projects" option unchecked

Importing with "Create module group for multi-module Maven projects" option checked (marked extra folders).

Is there are a direct way to switch the view without extra folders.

Note: This is just a sample small project. I am currently working on a very big project ~300 poms and in that case, there were lots of extra folder due to grouping and that too very complex structure of groups folders as original maven project structure is somewhat complex (nested pom projects)

1 hint: I guess this problem is happening when steps are being performed in the following fashion.

1. Import project with "Create module group for multi-module Maven projects" option unchecked.

2. Then import existing module (multi-maven project) and this time check the option "Create module group for multi-module Maven projects". Now, this module group folders appears in the new module also as well as the existing module also. Honestly, this view is quite frustrating and performance of IntelliJ really degrades in this view. As soon as I click anywhere in this project view complete IDE hangs - Version 2018.3

Why don't you keep "Create module group for multi-module Maven projects" option disabled?

I am looking for a solution to this. I have the same problem. In the project tree, I see three nodes: "myProject", "myProject C:\pathToMyProject", and "External Libraries". I don't want to see the first one because it's redundant and unnecessary.

The option to "Create module groups for multi-module Maven projects" was removed from our IDEs starting with version 2023.3. In recent versions, you can group modules by fully-qualified names.

To better understand the problem you are facing, I would kindly ask you to attach:

1. A screenshot of the current Project View tree with module names visible
2. A screenshot of the File | Project Structure | Modules dialog with all groups expanded

@... 

This is the Project View collapsed. I would like to hide the node I marked with the red arrow.

This module group disturbs me

I should perhaps explain that this project uses things from a third-party provider that I don't necessarily understand. Previously it worked with gradle 4.something and I only saw the second node (following picture). So no Module Group.
It was then updated to gradle 7.x with Kotlin and then intelliJ could also be updated.
And since then I see these redundant nodes.

Thank you Fchastagnol.

Does it help if you enable the option to flatten modules in Project View settings?

@... Thank you for your answer.

No, unfortunately it doesn't really help. Because I can then see all the modules. It's a bit better, but I don't need to see all the modules because I have them in the hierarchy (from the parent module ‘niagara’) and I'm just used to working this way.

@Fchastagnol Hi, can you please share `.idea/modules.xml` from this project root, upload it to https://uploads.jetbrains.com/, and share the upload id for investigating your issue?

Lejia Chen i do have the same issue as Fchastagnol mentioned. You can check out this repository https://github.com/adamdanielczyk/RLAD and open native-android directory in Android Studio. I'm currently on Android Studio Otter installed via Jetbrains Toolbox.

Also, it seems there is no ‘Flatten Modules’ option in view settings.

Version details:

Hi Dhruv Bansal 

Were you able to test the suggested workaround by Lejia Chen? How did it go? Did you see any difference in the project structure, or is the same problem still showing?

I gave up and did manage to ‘solve’ this issue by clearing all system data related to Android Studio:

```

❯ rm -rf \
"$HOME/Library/Application Support/Google"/AndroidStudio*(N) \
"$HOME/Library/Caches/Google"/AndroidStudio*(N) \
"$HOME/Library/Logs/Google"/AndroidStudio*(N) \
"$HOME/Library/Preferences"/AndroidStudio*(N) \
"$HOME/Library/Preferences/com.google.android.studio.plist"(N) \
"$HOME/Library/Application Support"/AndroidStudio*(N) \
"$HOME/Library/Caches"/AndroidStudio*(N) \
"$HOME/Library/Logs"/AndroidStudio*(N) \
"$HOME/Library/Preferences"/AndroidStudio*(N) \
"$HOME/Library/Saved Application State"/com.google.android.studio.savedState(N) \
"$HOME/Library/Application Support/JetBrains/Toolbox/apps/AndroidStudio"(N) \
"$HOME/Applications/JetBrains Toolbox/Android Studio.app"(N)

```

Clearing Jetbrains Toolbox data could help as well, although this might not be needed once Android Studio data is cleared:

```

❯ rm -rf \
"$HOME/Library/Application Support/JetBrains/Toolbox"(N) \
"$HOME/Library/Caches/JetBrains/Toolbox"(N) \
"$HOME/Library/Logs/JetBrains/Toolbox"(N) \
"$HOME/Library/Preferences/com.jetbrains.toolbox.plist"(N) \
"$HOME/Library/LaunchAgents/com.jetbrains.toolbox.plist"(N) \
"$HOME/Applications/JetBrains Toolbox.app"(N)

```

And importantly, on fresh reinstall of Android Studio I needed to make sure that ‘Backup and Sync’ feature which is new in Android Studio Otter did not restore my previously backed up settings - otherwise the issue would come back. So it seems there was something faulty in my configuration, although I did not find which setting that was exactly.

Hi Adam Danielczyk 

Thanks for coming back to reply. It's good to hear you found the solution.

As you mentioned, it appears to be some old configurations that could also have been spoiled, potentially interfering with the actual configuration of your IDE. Sometimes, files become corrupted for some reason, and they need to be restored.

I'm glad to hear you figured it out. Have a great day!
