When I open an existing Maven project, the IDE shows only those files on the root directory, but not any directories in the project. After a while, the IDE will show the project as what it is in the file structure, but not the directory types such as source code, test when I reopen the project. I reinstall the community edition, but the problem still resists. I have experienced the same issue for a few Java projects lately.
How to resolve this issue?
1, Please ask another teammate to check if that project really works. Sometimes the application structure already broken, then it is not your local problem.
2, There is a .idea folder in the application, delete it. Or simply, you git clone a new place Important: Please notice if you have edited / created some new files in the original directory, otherwise you would lost them if you delete the application.
3, Open intellij, and File -> Invalite caches
Personally, the second point is recommendated.
Try to click on Reload All Maven Projects in Maven tool window:
If it doesn't help you can try to perform the following actions:
Close the project with File | Close Project.
Close the IDE.
Open your project in OS file manager and remove all .iml files and the .idea directory.
Reimport the project.
If the problem remains contact JetBrains support and attach a compressed log folder along with the project structure tree.
I recently put several old, yucky git directory structures into one new, clean structure in SVN, then pulled the entire SVN repository back out into a new, clean, local git repository. One IntelliJ project was so messed up I had to import the old IntelliJ project, which created a new .iml file having a better name, and deleted the old .iml file. I reconfigured everything, committed back into SVN, and verified other people could open the project and build.
Today I tried to edit a file for the first time in this project and got the message, "These files do not belong to the project". IntelliJ offers to unlock the file or all non-project files in the current session, but both options sound wrong. What have I done to myself, and how do I fix it?
This happened for me when I ignored the .idea/ files. Just do
rm -rf .idea/
And then File -> Invalidate Caches/Restart -> Invalidate And Restart.
I figured out the problem. The file was still open from before all the shuffling, and was apparently pointing at the original file in its original location! I closed the editor and reopened the file from the project tree without a problem. I hope this helps someone else someday.
From File-> Repair IDE -> Rescan Project Indexes -> Reopen Project worked for me.
Had same problem on Ubuntu (Webstorm), got answer from Intellij.
There are no content roots in your project, so all your files are
treated as non-project files. As I wrote your .idea files are likely
broken, the .iml file and/or modules.xml are either missing or
corrupted. Deleting and re-creating .idea folder should help:
-close the project
-remove it from Recent projects list
-shut down the IDE
-delete the .idea folder
-restart, open the project root folder with File > Open
https://intellij-support.jetbrains.com/hc/en-us/requests/3779670?page=1
This also happened for me when I opened the project through a symlink (parent directory) or when the python interpreter was inside a symlink directory (because of virtualenv).
Reopening through the original directory tree (after fighting hard with the IDE to forget its beloved project settings), solved the issue.
It's probably listed in one of the XML config files in .idea/*.xml.
Just do a find of that folder for the name of the file in question, and remove the entry for it from the XML.
Mine was listed in .idea/workspace.xml within the following node: <component name="TypeScriptGeneratedFilesManager">.
I removed the option, then invalidated caches and restarted, and now the file is marked as a standard, non-generated file again. This way you can keep all your settings without exporting them and importing them.
Similar issue with WebStorm. The difference was I had to shutdown the IDE completely and then remove .idea folder
rm -rf .idea
I tried doing it with the IDE open and going to file File -> Invalidate Caches but that did not fix the problem for me.
Same problem. File was considered not part of the project even if I deleted it and created a new one with the same name.
To fix,I highlighted the project node in the left panel, selected "File/Invalidate caches and restart" from the top menu.
After the restart I had to set my file as a JS file (right click, set as JavaScript), close and reopen the project. All fixed.
For me the above did not help. I ended up going Project Structure -> Modules -> + at the top narrow middle column -> browsed through files to select the Project Folder -> apply -> ok -> all is done and working correctly.
My problem was much simpler than expected: I was trying to run a Jupyter notebook and got the error - because it was inside a folder that was marked "excluded" in the project structure.
Simply moving the notebook out of the excluded folder solved my problem.
In my case it was auto-generated .gitignore, I had entries like:
### npm ###
node
node_modules
frontend-dest
data/
And in project files I had java package called like com.company.test.data which matched last pattern. I strongly recommend to check it before removing .idea/ files and invalidating cache.
This warning is an IDE issue that Android Studio cannot recognise the current directory if it does not include any source files.
So, adding am empty source file, e.g empty_xxx.c under the directory in question and adding below line in CMakeList.txt
add_library(${TARGET_NAME_XXX} SHARED ${SOME_DIR_HAVING_THIS_WARNING}/empty_xxx.c)
will help get rid of this warning.
In my case the above methods didn't help, I just deleted .idea file in project and reset the Jetbrain IDE to default settings and it worked normally.
NB: You will loose all your settings and plugins, but if you don't mind this might help as the last resort like in my case.
I am using Jetbrain,
make sure to include all project files in the project. Use Settings -> project structure.
PyCharm > Preferences > Project > Project Structure > Add Content Root
Somehow PyCharm lost the project root directory in my case
For me it was because I had moved a project to wsl by copying the files from wsl to windows. When I switched branches the file must've been open from before and was the windows version of it and not the wsl one.
I noticed this finally by looking on top of the file tab and seeing the path as C:\User...\filename instead of \\wsl$....\filename.
Close your JetBrains IDE, then open a Terminal window and navigate to your project's root folder, and run these 2 commands:
rm -rf .idea
and then
rm -rf .git
NOTE: you'll probably have to connect your project back to your git repository, so if you have any uncommitted changes make sure to commit and push them beforehand to avoid losing them.
Every once in a while, I open an old project and I can't see any of the folders in the intelliJ project viewer. I can see all the files at the root.. but no folders. Yes I can delete the .iml file and .idea folder and re-create the project, but come on.. there's gotta be an easier way to fix this.
Is there?
If you look in project settings (ctrl-shift-alt-s), you should see a module structure. If you instead see "Nothing to see", do the following:
In Project Structure -> Modules, press the + button,
press enter (since, for some weird reason, it won't let me click on "New Module")
In the window that pops up, click on the "..." next to Content root, find your root folder, and select it
Press ok
ignore any warning that says the name is already in use (or to that effect)
the simplest solution worked from me, just delete the .idea folder
keep in mind this will delete all of idea's current project configuration, it'll create the folder with default settings when reload the project again... but all other configuration will be lost if not properly backed-up
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
Go to pom.xml file -> right click -> maven -> generate source and update folders. You will see your files and folder structures in left hand side.
All the project-specific settings for a project opened through Intellij IDE are stored in the .idea folder.
The .idea folder (hidden on OS X) in the solution root contains
IntelliJ’s project-specific settings files. These include per-project
details such as VCS mapping and run and debug configurations, as well
as per-user details, such as currently open files, navigation history
and currently selected configuration.
So, if you are not able to see the project file structure in your Intellij IDE, just delete the .idea folder,
rm -rf .idea
and reload the project, then after reload you'll be easily able to get your project structure displayed.
Thank you very much. I just remove the .idea folder and works in my case.
rm -rf .idea
For me, the java folder was not showing up. I went into File->Project Structure. In the second column, I selected on _main. In the third column, I selected the tab "sources". In what I call the fourth column, where the "+Add Content Root" is shown, I verified, the java source/folder was present. In my case, there was an extra source folder, which was the current location. I removed this, applied and the java folder immediately showed up.
Right click on the Project name -> Open Module Setting -> Check the application context path set it up at your project location.
Check your idea.log -- it may have some details explaining why or what is happening (Help | Reveal log in Explorer). Possibly one of the config files got corrupted.
You can always backup and delete .idea subfolder (project settings) and re-create project from scratch. When it's wroking again (after basic configuration) you may copy some of the files from that folder back to recover some of your settings (if there were many).
This happened to me on a new computer when I opened up a Java project in the newly installed Intellij.
The problem was that I had not installed any JDK on the machine.
I had to install a JDK and then go into the settings at ctrl-shift-alt-s and add a JDK by specifying the folder where I installed it. It's possible that IntelliJ would have found it if I closed it and reopened it.
In my case the solution was to create a new project, specifying the project type and creating it within the same directory path as the project that does not load the project files correctly.
PhpStorm automatically detects that the directory exists and gives you the option to create project from existing sources.
This can be found under:
File --> New project...
For gradle users: "Reload All Gradle Projects" option should help.
I have been working fine with Vaadin + Gradle + IntelliJ until yesterday night when I introduced SLF4J(logback) logging to my application. Since then I can't make my project anymore due to classDefFoundError of org/apache/tools/ant/util/ReaderInputStream.
I can't link it with any transitive dependency of any contained jar in application, but even if I remove SLF4J libraries I still can't make my application, so I am wondering what changed?
I am using vaadin gradle plugin 0.9.5 and gradle 2.2.1. Has anyone ever encountered this problem? I was reading another post where someone had the same issue, but the solution he proposed is not valid to my application. He proposed to comment some of the lines in vaadin.gradle, which my application doesn't have.
Try
File > Invalidate Caches / Restart...
File > Invalidate Caches / Restart... nor did git clean -dfx. Here is what I had to do:
Close IntelliJ
IMPORTANT: Make sure you have everything commited you care about (you're about to clean your working copy)
Run git clean -dfx to clean your working copy
Run IntelliJ
Select Import Project
Navigate to the directory containing your project
The select Import project from external model and select Gradle
Press Next
Make sure the settings on the next page look ok then press Finish
The build should now hopefully work
I deleted the .idea folder and that worked for me.
File > Invalidate Caches / Restart... option didn't work for me, but
sudo git clean -dfx worked fine
remove .idea and invalidating caches worked for me.
rm -r .idea/ in command line
in Intellij GUI File > Invalidate Caches / Restart...
After IntelliJ IDEA froze and was killed from the task manager, all the Run/Debug Configurations disappeared. I have tried invalidating caches, reloading files from disk, synchronizing and restarting, but nothing helped.
You can try to restore your Run configuration using the Local History feature of IntelliJ IDEA.
If you are using .idea directory based format, then your configurations will reside in workspace.xml file under .idea directory, invoke Local History dialog from the .idea directory right click menu in IDEA Project View, select the label some time before the crash and revert the old copy of workspace.xml.
In case .ipr file based format is used, your configurations will be stored in the <project>.iws file in the project root which you can restore in a similar way.
If the configurations were Shared, they are stored in .idea\runConfigurations directory as separate XML files or in the <project>.ipr file (if old project format is used).
If the Local history is blank and you are in Windows, try Restore previous versions right clicking the workspace.xml file or the <project>.iws one in Windows Explorer.
You can go to your main project and right click on it, select local history --> show history. Find some point in time where you think that system was stable (before crash) and click revert. This worked for me.
To me, this frequently happened on switching branches. Turning off "restore workspace on branch switching" helps to prevent the run configurations from getting lost.
Edit: Not sure if it actually has an impact, it still seems to happen to me sometimes, maybe less frequently though. I'll leave it here since the answer already has some upvotes, so maybe this was the solution for someone...
For every project in intellij there's a file created with all the configurations related to it.
Under the root directory of the project there's a hidden folder .idea in it is the workspace.xml with the configuration. workspace.xml is comprised of components one of which is responsible to hold the run/debug configurations.
If this file is getting corrupted it's difficult to restore these configurations if you don't have a backup of workspace.xml. to overcome it:
1. in intellij right click the workspace.xml file under project view and choose Local History -> Show History
2. if there's no history you can copy the component from a coworker with similar configurations.
3. backup in advance the workspace.xml and retrieve the RunManager component from it..
another good choice is to use the share option.
under each project's definition there's a checkbox share
Marking this checkbox will extract the definition for this project to an external location:
under the same .idea folder a new folder is being created runConfigurations and the configurations per project are being represented there in xml files.
The advantage of using share is that it can be copied and used for similar projects under other branched like QA and production
In my case, i've accidentally pressed Alt + Home and this bar disappeared, this combination toggles run bar at the top of IDEA window for me.
Here the screen with my bound actions on this keys. I hope it should help
Run configurations are stored in your project files. When IntelliJ (or your computer with IntelliJ running) crashes hard, the project files can become corrupted and unreadable. I don't know of a way to recover this unless you have your project files are backed up somewhere.
Navigate to your project folder and check weather any .idea folder is created or not,
if created copy your project and paste it other location ant try opening it;
it will work.
I sometimes have the problem that all the run/debug configurations are not created from CMake after being lost. I solved this by just deleting the whone list of configurations from the workspace.xml (from .idea folder).
This happened to me recently and I just restarted IntelliJ and they shared ones (in .run) are now restored.
In my case what happened was I did something that made IntelliJ recognize the project as a new application type, so it thought my old configuration was not valid for my project anymore and wasn't displaying it to me. I reverted my changes and the configuration appeared as an option again.
I guess this feature can't be removed from IntelliJ but I guess this can help:
Run/Debug configuration functionality might be hidden, so to show it go to:
View/Appearance/Navigation Bar
Very annoying problem in Intellij Idea for many years.
It's quite often breaks because of broken (connection to?) Ant debugger, used to create run configs.
I was periodically searching for a solution, but no success. Then today after disappeared Run Config to display in panel I did inspect contents of workspace.xml. All the run configs were there.
And then it turns out to be 7+ years bug clue...
Always spring out non-called Ant...
Happily, contents of workspace.xml in place with all your run config items, you can just
disable infamous plugin Ant debugger,
reload the project,
and all your run configs are displayed and available again))).
Happy to share with all of you the solution).
