I'm developing a JavaScript/React application in Intellij Idea and I'm using webpack-dev-server to incrementally build my files. That means that the dev server is watching the files and if a file gets changes, webpack rebuilds it. Pretty standard scenario.
Unfortunately, webpack sometimes decides to ignore certain files. I can change them all I want but webpack does nothing. I have not been able to determine any pattern on which files get ignored. It's arbitrary. Sometimes I just create a new file and webpack ignores it.
What is interesting though is that it only happens when I perform the save using Intellij Idea. If I open the file in another editor (for example vim) and save it, the file gets correctly rebuilt. Actually, simple touch file.js is enough to trigger rebuilding.
I guess there is something wrong in how Intellij Idea saves files. Any ideas?
This is due to an IDE feature known as "safe write". When enabled, the IDE will write the changes to a temporary file over the real one. This means webpack's file watching mechanism cannot pick up the changes. Disable this feature to fix the problem. Reference.
For me this did not work, I'm posting this in case anyone has the same scenario. After each save, webpack watch script builds the new bundles and I'm reloading all files from disk (CTRL + ALT + Y). Only after that the changes are visible.
There is an open issue "Background" changes by external tool not being picked up until VFS refresh happens regarding this behavior: file is saved but one has to reload all from disk in order to see the changes (for example in the browser).

I'm a newbie to both IntelliJ and Aurelia. I did my last web project almost a decade ago, and I find myself a bit lost between all those new libraries. That said, my question is probably of rather trivial nature:
I've downloaded the Aurelia skeleton project [1], imported the sources into a new node js project in IntelliJ and started index.html. Voila. Browser opens, shows the site.
Then I changed something (added a new route to src/app.js).
I hit the run button to show index.html again: No changes. Hm?
I rebuild the project in IntelliJ, and retried. Still my changes aren't shown.
I run gulp watch on the command line, open the browser, and my changes are shown.
So, I'm asking two things: What needs to be done to really refresh the build within IntelliJ?
And secondly, when did it become a sport to create inter-depending Javascript libraries with blurry names? Just kidding... (though I'm not laughing)

I found it out myself. You need to put 'gulp build' to the pre-launch list of the run configuration. This is because the sources get transpiled and copied to the dist directory, from where the server is actually running.
Just building the sources from IntelliJ isn't enough.
Project rebuild start automatically after any files was changed in project directory. You do not need to build it from IDE-- only save your changes and wait a few seconds to refresh.
Of cause it will work only when you run project build with watch statement like gulp watch (e.g. run gulp watch and your project will rebuild automatically).
But if there were some errors in code -- gulp process will stop and you must restart it again. I recommend you change IDE's settings to disable automatically saving to files and use <CTRL+S> buttons to save data manually.
Without "excluding" folders, how can I stop Indexing intellij idea on start? It's very very annoying that it starts indexing on startup without allowing you to, for example, debug a test case making you wait until indexing has finished.
You can stop synchronizing/indexing each time you switch to the IDEA and it's quite useful when dealing with big projects and outside build process which triggers indexing.
Just disable checkbox System Settings -> Synchronize files on frame or editor tab activation.
Make sure you run indexing manually to update hints when needed through Synchronize menu (Cmd-Alt-Y on Mac) or File -> Reload All from Disk to run it manually for IDEA 2020 running under Linux
Try:
File-> Invalidate Caches / Restart.
I think that this issue happens (at least for me it seems to be the reason) if you start commit and then close the IDE in the middle of the process.
Now, "excluding" folders is the only way to disable indexing when a change occurs in one of excluded folders (except for generated sources that mustn't be excluded).
Checked with Intellij 2016.2.5
I suggest you to tune your Intellij configuration, see this post : https://stackoverflow.com/a/22508853/779338
You Can easily resolve it.
Just Go to: File -> Setting -> Directories.
Stop all the files that are going to included and need to empty ADD Content Root.
Like This:
It may be because of libraries folder is added more than one sub folder in the project. example in my case i have node_modules folder in two locations in the project. one is under root directory(app-->node_modeules) another one is under(app-->test-->node_modules)
Simply Right click on each folder and then selected Mark Directory As --> Excluded
It resolved my problem. Hope it would be helpful.
After struggling with this issue for around a week and searching all the solution I came to below conclusion:
either upgrade your intellij which gives you feature to pause the indexing ( I can't upgrade my intellij due to license issues ) so the other option was to disable all the plugins and then try enabling as per the need one by one.
After enabling any of the plugin if you see it behaving the same uninstall the plugin and download some alternative of it.
If longer indexing is an issue you can enable the shared indexes.
Add this plugin in your intellij and follow the instructions from here.
In my case i had constantly indexing files in Angular application when i remove node_modules folder.
I've tried to invalidate caches multiple times what didn't help at all.
Only solution was to remove project with clear Git state and reclone project - than everything started to work just flawlessly.
I use automatic deploy through FTP. Everything worked well until I started to use coffeescript and its filewatcher feature which recompiles my .coffee file into .js file on every change.
Problem is that IDEA don't want to upload these compiled files like others. So I have manually press hotkey to upload compiled file after every change, which I want to see on the server.
How can I do it more convenient to use?
There is an option to upload external changes automatically.
Right now IDEA will not perform synchronization after file watcher is invoked, so you will need to do File | Synchronize, IDE will detect the changes and upload them.
Next update will have an option for the file watcher to perform synchronization after execution as the result of addressing this feature request.
this feature request concerns to a possibility to synchronize all files in output directory on every change (required by some transpilers). But, AFAIK, this is not the case for CoffeeScript compiler - synchronization should work there. Do the generated js files appear in the Project View as soon as the compilation completes, or do you have to synchronize the view manually to see changes? In the latter case something must be wrong with file watcher configuration (output path set incorrectly, for example). If files are synchronized correctly, setting 'upload external changes' option should do the thing
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).
Let's say I have a mediawiki installation. I mess about with it, add little hacks to make the wikipedia logo change into tigger, and bounce up and down.
Now it's time to update to the newest version, so I download it and run the update script. Let say it changed several variables, like $wglogo, the image path to the logo. How does the update script ensure that the logo image path changes (according to the specs of the new version, in this figurative example), while keeping tigger bouncing on the main page?
That is: How do new versions integrate changes to the configuration file without overwriting the user-defined changes in the config file-to-be-overwrit?
Typically we try not to change config files on update. Almost all new configuration settings are optional and thus are not added to the config files upon upgrade. In the rare case where we have to change an existing setting, make the smallest change required to the config file so as not to affect any other things.
Testing is very important. Gather as many real client configurations as possible and create unit tests for the auto-updater to validate that the configs don't gets screwed upon upgrade.
