IntelliJ IDEA missing some classes in autocomplete - intellij-idea

I have quite a few libraries attached to my project and in Eclipse it shows me all my classes that are available to me when I press Ctrl+space.
But with IntelliJ IDEA so many are missing and even when I press Ctrl+space twice it still does not show up.
How ever it does come up when I use goto class(Ctrl + N) it fines it ill add 2 print screens as an example:

Opened up a bug on the jetbrains tracker and Peter Gromov got back to me with "its a bug to do with starting a class with a small letter." The said bug is documented here
Peter suggested that I use the new version of Intellij Idea 13 in which this issue was fixed.
Update
It works on Intellij Idea 13 (as suggested by Peter), so indeed it was an issue with the first character being a lower case character.

By default IntelliJ IDEA come with a "first letter" case sensitive. Here's the place to change that value to "None".

Alt+Enter does not work properly IntelliJ [duplicate]

When working with IntelliJ on a JavaProject it shows to use alt + enter to import a class for example, but this isnt working anymore. It worked in the past, but something must have changed, -the shortcut is still set,-other shortcut would work- i cant assign alt+enter manually, although if i reset it to default it gets set to it, any ideas how to fix my problem? btw my keyboard layout is german, but i dont think it is the problem because it worked in the past, my os is win 7. edited: when i am working within the IDE and i e.g. write Arrays.toString(a); and didn't import "java.util.Arrays" yet, the IDE says: " ? java.util.Arrays? Alt+Eingabe"    (Eingabe = Enter in German) so when i assign a different shortcut it works, but with Alt+Enter it doesnt thanks in advance for any help.
"Well, it means IDE doesn't see the shortcut for some reason. Probably it's already used by some other application or the operating system. – CrazyCoder 25 mins ago "
i closed all applications and it turns out that, Facebook GameRoom, running in the background, somehow is the reason the shortcut doesn't work, i have no idea why, but thats the solution
many thanks to CrazyCoder
It was working earlier but it stopped working due to unknown reason,
One workaround is Try fn+Alt+Enter
I had the same problem
and it turned out to be the keyboard language in Windows, It wasn't english,
so just make sure you are on English
On my side, culprit is some VPN software called PulseSecure
fn + Alt+Enter+Shift worked for me (credits #ketankk).
My problem solved. just try :
LEFT Alt + Enter
LEFT Alt+Enter
Looks like some languages override Right Alt behavior, at least in case of Lithuanian Left Alt is working fine with Lithuanian enabled, Right does not, when switch to English, everything is fine again. Was pulling hair to figure out why out of nowhere it stops working, thanks
In my case hint is showing Alt + Shift + Enter, but Ctrl+Shift+Enter works for some reason oO
In my case, I mapped Alt+Enter to a system shortcut (for expanding the current window) and I forgot. So it might not be another program, but your past self-sabotaging you.
I have the same issue. Alt+Insert not working while I was trying to generate getters/setters for my POJO class.
I just added another shortcut for that "Generate" operation.
If you are using Intellij Idea, you can do that by following steps:
Go to File -> Settings -> Keymap.
On the search bar appeared, search for "Generate", you will find an entry to which assigned shortcut will be Alt+Insert.
Right click on this entry and select 'Add Keyboard shorcut'.
Now, type your own shortcut that you want. In my case, I used Ctrl+Shift+G.
It worked fine and now I am using my new shortcut for Generate operation.
I had the same problem while upgrading to a new IDE version. The cause was a plugin error in new IDE version, I resolved disabling/updating that plugin.

WebStorm, how to disabled "virtual space" in the middle of text?

This is freaking annoying me. I don't know which option do this, but it is really bothering me so much.
The problem is that WebStorm add a "virtual" space after each text like function or object (picture 1). You can see it because clearly in the highlight text (picture 2).
Also, when I am writing on a line, the text is push right to the caret (picture 3)
I want to know which option is it, to disable it.
There is an open issue for this problem:
IDEA-154843 There is a space coming between cursor and the next letter when typing or the cursor is moved.
It definitely helps to select a different font, but reinstalling the latest version of Source Code Pro font may also help.
UPDATE:
It should be already fixed in latest 2017.1 builds.
Thanks the tip from user #yole & user #LazyOne, the problem was the font "Source Code Pro". Changing the font, solve the problem.
As user #CrazyCoder has link this question to an open bug, the next is information for Jetbrains Developers.

Idea treats 'Ctrl + Slash' as 'Ctrl + Period' in hotkeys

So I've just migrated to Fedora Linux and ran over this problem when using my Idea. I have a notebook (no numpad) and I previously used the very same Idea (Ultimate, latest) with Win10 on this very same notebook and did not experience this.
I use default English layout. In the lower row of QWERTY, to the right there is / button which is also ? with shift. It works as expected anywhere else, but in Idea, when I use it as a CTRL + / shortcut it actually treats it as a Ctrl + . Thus, instead of commenting selected block of code, it collapses it. I checked it in Settings -> Keymap and this is exactly how Idea interprets it.
Is there any way to change this back to normal? I don't really want to rebind this hotkey as I'm used to it by now.
Posting a workaround that helped me.
So the bug i'm experiencing is this one and it's weird how the bug is still there.
So in my case it didn't work as expected because I had Russian keyboard layout set as first. Switching Russian to second and English to first fixed the problem for me. That's not really a 'solution', rather than a 'workaround', but it worked for me.

Can't type in IntelliJ

I'm using IntelliJ IDEA on my Mac to work on a project, and I keep on coming across an issue where I can't type. Occasionally when I switch to another application and then switch back to IntelliJ I can't type anything, and the cursor doesn't appear on text when I click on things. Does anyone know what causes this? After 1-2 minutes it goes back to normal, but it's started happening more frequently and it's pretty frustrating to not be able to type and have no way to fix it.
This is the version of IntelliJ I'm using:
IntelliJ IDEA 2016.1.3
Build #IC-145.1617, built on June 3, 2016
JRE: 1.8.0_76-release-b198 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Turn off Vim Emulator from Tools in the IntelliJ, like this picture:
I am encountering this issue aswell, ...
MAC os Mojave 10.14.2, Inteliij Community 2018.3.5
Aside from restarting / clearing caches, I found that cmd + leftShift + F still opens the search window, and all my keystrokes appeared in the searchbox!
After the searchshortcut, I was able to close the searchbox and work again!
The answer here helped me https://intellij-support.jetbrains.com/hc/en-us/community/posts/206152119-Can-t-type-in-editor-window
Quoting the author of the answer:
I had the same problem. It goes away after I click the icon at top of
the scroll bar. it happens frequently on windows 7/10, and
occasionally on mac. my colleagues said they have experienced it too
Have the same issue occasionally, can't type in any Intellij windows. My temporary/quick fix, is to:
Close any terminal windows in intellij
Use cmd+shift+f to pull up the search window.
Seems to fix it, for a while.
Closed IDEA, all IDEA projects! Even though in other IDEA windows I could type.
Removed .idea folder in the project I could not edit.
Restarted IDEA.
Then I was able to type!
Maybe you entered Vim emulator as said. Maybe only by mistake :).
Control-V is a frequently used shortcut. And Control-Alt_V is the shortcut to enable Vim mode so you can see the problem...
How to know in five seconds: type a ":" (colon) and if the cursor jump to end of the screen, that is vim. If so enter q to quit and then Control-Alt-V (on windows) to go back to IDEA standard mode.
vi is a powerful text editor since ever. But only if you pretend and know how to use it... There is even a warning on the IDEA install saying like "do not install unless you are familiar with Vim" in yellow bold text, iirc.
[Follows historic data, that you may find boring off-topic or interesting]
Today's editors opens the code in edit mode right away so you can start typing over existing code. Vim by the other hand opens the code in, let us say, browsing mode: there is a set of navigation keys to browse the code. Everything you type is supposed to be a command. When you want to edit you enter INSERT mode and then you can type new text. Only then.
Just for more historic data: vi navigation mode is great for studying code you do not know, using IDEA, since it does not change the text unless you tell it to, and some vi commands are clever.
One example:
"/" (forward slash) is one search command, and "z" is a smart scroll command so that:
/setCellFactory will search for the next match of "setCellFactory" and put the cursor there
Then if you type "z" the code will be positioned so that line is the first on screen. And if you type "." the line will be at the middle. And if you type "-" that line will be at the last position at the screen. And you can use these commands again and again. And new slash will go for the next match, like F3
This "z" thing is a feature I miss in Visual Studio, IDEA, Eclipse, Word, WordPad: these commands to scroll text AROUND a pattern... /pattern, z, z., z-. The alternative is the mouse wheel...
I am used to vi since the 80's and is the editor I still use today on Linux terminals so when this happened to me on IDEA I was lucky to remember and suspect of that on the first time.
Sorry if these details are boring
Ensure you haven't unintentionally enabled vim emulation. Go to IntelliJ Idea -> Preferences and select Plugins. Scroll down and look for the vim emulation plugin and if it's checked, then either uncheck it or uninstall it completely.
Ran into same issue with intelliJ 2017.1.2, but no VIM Plugin. However, I had just created an empty project with some .groovy files. I could edit the files in the groovy project, but not java projects.
Only way I could fix java projects, was blow-away workspace.xml files in each, then I could edit again. However, had to re-create tomcat configs, breakpoints, other IDE settings. etc.
I had a problem with entering characters when working with .story files. When I tried to type in any character, it appeared for a short while and immediately disappeared. The cause of the problem was jbehave plugin I was using. After uninstalling it and restarting IntelliJ everything was fine.
It seems to be because another window has the cursor and is not giving it back.
Check any open floated windows, click on them & then click back to your intellij instance
alternatively, if you have multiple intellij instances open the cursor could be there...
Go to the most recently opened IntelliJ instance
Check if the cursor has become stuck in that project's terminal window, or another window
no? check all other open IntelliJ instances
For me it happened because of vim
Om Mac, I solved it by navigating to File → Reload All from Disk.
Keyboard shortcut: ⌥ ⌘ Y
IntelliJ IDEA 2020.1.4
Try disabling plugins one at a time. It was the "BashSupport Pro" plugin that caused it for me. Disabled it and I could type again right away.
I read other comments saying some other plugins caused the issue as well.

Disable IntelliJ Warnings

It really annoys me that IntelliJ highlights certain 'errors' (that don't prevent successful compilation) the same way that real errors are highlighted. For example, a magic number is not really an error, but it will be flagged in exactly the same way as an incompatible type error.
How can I change this?
Go to Settings -> Inspections. Then you need to search through the long list for the offending inspection, which you can get the name of by hovering on the warning marker in the margin. You can change the severity of the inspection, whether it's an error, warning, etc. or just disable it altogether.
Edit: if you search for "magic" in Settings, you get the following, which should be helpful:
Whenever you see an inspection warning/error you can place the caret on it and press Alt+Enter (a light bulb also appears that tells you that). A menu will appear with suggested quick fixes. You may need to open a submenu by pressing Right, and you'll find "Edit inspection settings" there. Having invoked that, you may proceed as in hvgotcodes's answer :), it's just a faster way of getting to those settings.
As Michael Calvin said you can use the SuppressWarnings annotation. For example:
#SuppressWarnings("OptionalUsedAsFieldOrParameterType")
See https://github.com/JetBrains/intellij-community/blob/master/plugins/InspectionGadgets/src/inspectionDescriptions/OptionalUsedAsFieldOrParameterType.html
Usually searching the internet for the exact description leads me to this.

I got to this question while trying to figure out how to disable IntelliJ IDEA's warnings about Guava functionalities that have been replaced by Java 8 features. I'm not able to use the Java 8 versions of these features in my case because of a library we're using that was built with Guava (despite being a Java 8 project). So to solve that, I added a SuppressWarnings annotation before any class using Guava:
#SuppressWarnings(Guava)
public final class...
