'IntelliJ does not show project folders

I have an issue with IntelliJ. It doesn't show any folders in my project view on the left. My setting is "View As: Project" How can I manage it so that the folders and packages are shown again? I don't have any clue because I didn't change any options!

I'm using IntelliJ 10.0.3. I am working on a Maven Lift Project.

intellij-idea

So after asking another question, someone helped me figure out that under File > Project Structure > Modules, there's supposed to be stuff there. If it's empty (says "Nothing to show"), do the following:

In File > Project Structure > Modules, click the "+" button,
Press Enter (because weirdly it won't let me click on "New Module")
In the window that pops up, click on the "..." next button which takes you to the Content root. Find your root folder and select it
Click the "ok" button
Ignore any warning that says the name is already in use

I had to quit Intellij and remove the .idea folder (I stashed it first, just in case). I then re-opened the project and that worked for me. Don't forget to save your configuration (e.g. debug / run configurations) before that, because they will also be deleted.

Solution 3:^[3]

I had this issue as well. It is something do with .idea just delete it and restart IntelliJ

Solution 4:^[4]

I went to File -> Project Structure -> Modules clicked on + and then import module found my root folder and selected it.

It worked.

For IntelliJ 14

Solution 5:^[5]

I am a new user of IntelliJ IDEA 2016.2. I opened an existing project when I first ran the program and had the same issue whereby it only showed files in the root directory in the 1. Project panel, but not the project folders (expandable tree-like structure).

Initially, I tried going to Project Settings > Modules, where no modules were shown listed. I clicked (+), and tried to select my root folder, but it wouldn't select the folder.

So I then solved it with these steps instead:

Exit IntelliJ
Delete the existing .idea folder (i.e. rm -rf .idea)
Restart IntelliJ
Verified that the project root folder now appeared (in Project Settings > Modules)
Toggle On the toolbar buttons (i.e. 1. Project Structure) to display on the left sidebar (clicked View > Toolbar Buttons until tick appears)
Click 1. Project Structure toolbar button until its sidebar is revealed
Click the arrow icon on the left of your project's root directory name that appears to expand the tree folder structure

UPDATE 2nd Sept 2017: If you've added a Module SDK and it added a .iml file within a subdirectory of the root of your project that causes it to load the module subdirectory, then it may be necessary for you to modify that .iml file by appending /.. as shown below.

  <component name="NewModuleRootManager" inherit-compiler-output="true">
    <exclude-output />
    <content url="file://$MODULE_DIR$/..">

Try to re-import the Maven project. Also make sure that the project directory name is not excluded in Settings | File Types | Ignore Files and Folders.

Solution 7:^[7]

close intellij
delete .idea folder
restart intellij
click import, select your project
create project from existing sources, click next, next, next

And you should be good to go.

Solution 8:^[8]

You don't have to quit Intellij completely to make this work. Simply close the project that you have open. (You can open any another project to avoid closing it completely)
Go to the directory where you have your project installed and delete the ".idea" folder.
Reopen the Project.

That should fix it. It worked for me in May 2018.

Check out answer at

Can't see project folders in IntelliJ IDEA

It might be because the project didn't have any modules defined. Try adding existing source code by hitting File > New > Module from Existing Sources and select the parent directory of the project for source code

Solution 10:^[10]

I have deleted the .idea folder. Closed ItelliJ and restarted to open the same project.

It asked to add the content root. That worked for me.

Solution 11:^[11]

Deleting .idea/workspace.xml worked for me. Close the project, delete .idea/workspace.xml, and open the project again. I was using version 2019.1.

Solution 12:^[12]

I faced same issue when i deleted the .idea folder.

However, when I tried to invalidate and re-start, the .idea folder got created again but still the folders were not showing up.

I had to 1.close IntelliJ, 2.delete the .idea folder, 3.launch IntelliJ

This fixed the issue.

Solution 13:^[13]

I have a better solution that worked for me and it might work for you. No need to delete the whole .idea folder as this way you lose the whole project. It is possible that you just accidentally excluded all folders in project settings. I also found that project folders disappeared. I was trying to find out how to disable indexing, so I was looking at Project Settings -> Modules and I clicked on Excluded to see if I could add the whole project there to ignore it for indexing. It didn't do anything and I couldn't drag and drop the folder under Excluded. What I didn't realize is that simply clicking "Excluded", IntelliJ automatically moves the folder to Excluded and all folders disappeared in Project Explorer. "Excluded" button changes background to gray, which means exclusion is active. This is a very poor user interface because it is hardly noticeable and clicking this button has a far-reaching impact on your project.

Fix:

Open Project Settings -> Modules
If Excluded is highlighted, click on it
Click Apply or Close

Result: Folders in your project show up again

Really bad bad bad UI design! Source and Excluded buttons look like tabs when they work in fact as "Checkboxes"!

Be careful, just clicking Sources or Excluded seems like an innocent selection of tab without any visible effect, yet it has far-reaching consequences, basically adding or removing files from the build process.

Solution 14:^[14]

Change the "Project" dropdown to be "Project Files"

I understand this does not answer the OPs question involving Maven modules, but this is the number 1 search result on Google as of July 2021 when trying to debug why folders are not displaying correctly in IntelliJ

Solution 15:^[15]

Backup the .idea folder into a zip file
Delete .idea folder
Reopen the project
Close the project
Extract backup files into the new fresh generated .idea folder
Reopen the project
Praise the sun ?? \[T]/

Solution 16:^[16]

I have a nodeJs project and lost my folders after removing the /[project_name].iml file.

This restored the folders while preserving my other project settings:

Project Settings > Modules
+ Add Content Root

Solution 17:^[17]

for me removing the .idea folder from the project directory worked.

Solution 18:^[18]

Even after 5 years, and having some experience with idea, I still have this problem all the times. Here is the simplest solution.

Close Idea
Delete .idea
Start Idea and open project instead of import project

And then, open conf file for your framework, like pom.xml or build.sbt or build.gradle etc and it will automatically prompts to import project and when you click and when it finishes, your project is mostly setup correct.

Solution 19:^[19]

OS:Mac && IDE: IntelliJ && Project: Maven build

Navigate to File>Project Structure>Modules.
In right-hand area; list of modules would be present.
Delete the default one selected and close IntelliJ.
Next Open again; IntelliJ will ask if you want to treat the project as Maven project.
Accept that popup and you are good to go.

Solution 20:^[20]

Intellij imports the project after resolving all the dependencies. In my case, it was unable to resolve dependencies for some of the modules and was stuck there. I had to copy my Maven settings.xml from local repo to the default .m2 folder in order to point it to the correct local repo.

Solution 21:^[21]

Adding this answer for completeness. I was using 15.0.6 and had this problem. I trued to import a module from Maven or Gradle an it went through the process, but the module did not appear. I tried deleting the .idea file and restarting. Uninstalling and installing the latest version (community 2016.2) addressed the problem.

Solution 22:^[22]

Select the module settings and do these changes, it will work

In File > Project Structure > Modules, click the "+" button,

add new module as per your project specific like Java or RUBY or something then apply and ok

Solution 23:^[23]

I had the problem after an upgrade from intellij 15 (v143) to 2016.3 (v163). I also had an intermittent error on startup about a "Load error: undefined path variables" with a cryptic variable name.

After countless attempts at most solutions presented here (reimport the project, invalidate caches & restart, checks of project structure and paths...), the only thing that worked was to completely reinstall Intellij (removing the ~/.idea* ~/.IntellijIdea*) and selecting "No" at the question "would you like to migrate previous settings".

This finally worked.

Solution 24:^[24]

As I had the same issue and none of the above worked for me, this is what I did! I know it is a grumpy solution but at least it finally worked! I am not sure why only this method worked. It should be some weird cache in my PC?

I did close IntelliJ
I did completely remove the .idea folder from my project
I did move the folder demo-project to demo-project-temp
I did create a new empty folder demo-project
I did open this empty folder with intelliJ
I did move all the content demo-project-temp. Don't forget to also move the hidden files
Press right click "Synchronize" to your project
You should see all the files and folders now!
Now you can also safely remove the folder demo-project-temp. If you are on linux or MAC do it with rmdir demo-project-temp just to make sure that your folder is empty

Solution 25:^[25]

For me, it happens when i set Project SDK as JAVA SDK 14 in a react-native project. Upon unset, all the folders show up again.

Solution 26:^[26]

Project Structure => Modules => Select your module => Paths => Make sure "Inherit project compile output path" is selected

Solution 27:^[27]

I just had the same problem with an SBT project in IntelliJ 2016.2 after removing a globally installed IntelliJ and re-installing in my own home folder (Linux). No files or folders were shown in Project View anymore.

The Project Structure view wouldn't even open, and renaming the .idea folder to .idea.bak and re-importing the project didn't make any difference.

However, what fixed it for me was to reboot Linux. Afterwards it worked again, even with the original .idea folder. Seems this "fix" is not only restricted to the Windows world.

Solution 28:^[28]

If you have a gradle module with the same name as your projects root folder, the gradle import will replace your toplevel module configuration and change your view completely.

Make sure you have no gradle module with the same name as your root directory.

Solution 29:^[29]

I encountered this problem when the .idea folder was accidentally added to SVN version control. When I took an update --- blooey! I subsequently removed the .idea folder from version control.

Solution 30:^[30]

I tried all the solutions above, nothing worked.

Java-Maven project

My problem: In my case i had java-maven project. And the problem was that Idea by default uses it's bundled maven for projects(or anyone you trying to open). I noticed that bundled maven keeps downloading dependencies forever, i.e you never see your sources folder.

Solution: So to configure that, one needs to configure Idea to use maven(mvn) which is installed on the machine for all projects by default. To do that, in the beginning when Idea still did not open any projects...there is a configure button. There chose build tools. Then maven, there you will see dropdown list where you can choose local maven. In short: Configure/Build Tools/Maven/DropdownMenu (My OS: linux branch)

Hope that helps
