If I change the code the color will disappear, I do not know how does this happen.and when do we will use this features.
It looks like you accidentally pressed the Coverage button instead of the Run or Debug button next to it.
To remove the red background color do the following: in the Coverage view click the Remove Active Session or Remove All Sessions button.
For information on what this Coverage does and what it is used for, see the EclEmma web site.
This is activated because of code coverage. If you want to remove it then follow these steps.
Go to "Windows -> Show View -> Coverage" Select it. Click on "Open".
Open the "Coverage" view.
There are "X" and "XX" signs at upper right side.
Click on one of them as per your requirement to remove the coverage session.
Refer the screenshot for more details.
In IntelliJ it seems like whenever I save a file there is this annoying green pop-up notifier at the very bottom that obscures my bottom toolbar, i.e. where terminal, messages, debug usually are.
It's usually "Refreshed selected content roots" which I believe is a gradle thing. There is no obvious way to dismiss it and it just trips me up every time.
As I often make a change and then want to switch to SonarLint or Terminal or whatever and it's blocking the button.
I know obvious workarounds like moving buttons around, but I kind of don't understand what that notifier is even called to configure it or even google it.
As #CrazyCoder would know what he's talking about, I found that the alert is caused by the (hasn't been updated in years with no configurable settings) AccuRev Plugin.
You can search this PDF for "Selected Content Roots" and you'll find it:
https://supportline.microfocus.com/Documentation/books/AccuRev/Plugins/IntelliJ/2014.2/intellij-2014.2-users_guide-en.pdf
This means if I don't plan on moving files around I can logout or disable the plugin then run accurev stat -mO when I'm done. There have been plenty of other reasons to do that, so this just added to the heap.
I'm developing a standalone server (not a war) using Eclipse Juno. I run it as a Java application from Eclipse. After I've made some code changes, I want to stop the currently running server and start it up again. I do this tens of times a day.
The way I do that at the moment is as follows:
- Go to the "Debug" tab.
- Select the server process.
- Click on the stop process icon (red square).
- Click on the green arrow to re-run the last run application.
- Go back to the "Java" tab.
Is there a quicker way?
Ideally, I'd like a button or keyboard shortcut that would stop and restart the application in one click. If it doesn't already exist, can I extend Eclipse in some way? Where should I look for an example of something like this?
You can restart running application by right clicking it in debug window and selecting "Terminate and relaunch".
And quickly switching beetween views with Ctrl+F8
Also if you've already terminated the application from console, you can simply hit ctrl + f11
If you really want you can also add custom shortcut for terminating and relaunching by Window -> Preferences -> General -> Keys -> Find "Terminate and Relaunch" and choose your favorite key combination!
Eclipse Neon.1 added a way to terminate before relaunch by holding Shift while clicking on a launch history item.
You can also make that the default behaviour by enabling the option “Terminate and Relaunch while launching” in Preferences › Run/Debug › Launching.
https://www.eclipse.org/eclipse/news/4.6/platform.php#terminate-relaunch-history
I had the exact problem you had. I had a simple Java class with a main method that runs an embedded tomcat.
When I change any of my service classes, I wanted to terminate the current embedded tomcat and relaunch with one single keystroke.
I know, I could have just clicked and done the same with 2 mouse clicks... but... it pained me enough to learn a wee wee bit about Eclipse plugin and threw something together.
Hope this helps you too.

Simply saying, You can't modify eclipse Like you wants to. But You can follow this procedure to minimize your effort
1. In Eclipse Project TAb-> Check Build Automatically.
2. And After Every Changes You are making Just Run The Project using Green button in eclipse.
Also you Can use CTRL+F11 to run project.
In Eclipse, when hovering over a method, variable, etc. a tooltip is displayed with the corresponding JavaDocs. Is there such a feature in IntelliJ?
For IntelliJ 13, there is a checkbox in Editor's page in IDE Settings
EDIT: For IntelliJ 14, the option has been moved to Editor > General page. It's the last option in the "Other" group. (For Mac the option is under the menu "IntelliJ Idea" > "Preferences").
EDIT: For IntelliJ 16, it's the second-to-last option in Editor > General > Other.
EDIT: For IntelliJ Ultimate 2016.1, it's been moved to Editor > General > Code Completion.
EDIT: For IntelliJ Ultimate 2017.2, aka IntelliJ IDEA 2017.2.3, there are actually two options:
In Editor > General > Other (section) > Show quick documentation on mouse move - delay 500 ms
Select this check box to show quick documentation for the symbol at caret. The quick documentation pop-up window appears after the specified delay.
In Editor > General > Code Completion (sub-item) > Autopopup documention in 1000 ms, for explicitly invoked completion
Select this check box to have IntelliJ IDEA automatically show a pop-up window with the documentation for the class, method, or field currently highlighted in the lookup list. If this check box is not selected, use Ctrl+Q to show quick documentation for the element at caret.
Quick documentation window will automatically pop up with the specified delay in those cases only, when code completion has been invoked explicitly. For the automatic code completion list, documentation window will only show up on pressing Ctrl+Q.
EDIT: For IntelliJ Ultimate 2020.3, the first option is now located under Editor > Code Editing > Quick Documentation > Show quick documentation on mouse move
Up until IntelliJ version 11, no, not just by hovering over it. If the cursor is inside the method- or attribute name, then CTRL+Q will show the JavaDoc on *nix and Windows. On MacOSX, this is CTRL+J.
Quote: "No, the only way to see the full javadoc is to use Quick Doc (Ctrl-Q)." -- http://devnet.jetbrains.net/thread/121174
EDIT
Since IntelliJ 12.1, this is possible. See #ADNow's answer.
It is possible in 12.1.
Find idea.properties in the BIN folder inside of wherever your IDE is installed, e.g. C:\Program Files (x86)\JetBrains\IntelliJ\bin
Add a new line to the end of that file:
auto.show.quick.doc=true
Start IDEA and just hover your mouse over something:
After doing CTRL+Q, you can
Pin the tooltip (top right corner)
Check Docked Mode (under gear in top right after pinning)
Size as desired
Click icon for Auto show documentation for selected item
Then when you move your cursor, the documentation will appear in this box. It costs you a little screen real estate, but I find it's worth it.
I'd post a screenshot but SO won't let me post images.
For Intellij 15, use the checkbox in File > Settings > Editor > General option Show quick documentation on mouse move.
You can also get there by typing "quick" or something similar in the search box:
In Intellij13, you can use Editor configuration like below:
IntelliJ IDEA 14.0.3 Ultimate: Press Ctrl+Alt+S, then choose Editor\General choose Show quick domentation on mouse move
Tips: Look at the top right conner (gear icon) at JavaDoc pop-up window, You can choose:
- Show Toolbar
- Pinded Mode
- Docked Mode
- Floatting Mode
- Split Mode
Adding on to what ADNow said. On the Macintosh:
Right click on IntelliJ IDEA 12
Click on the Show Package Contents menu option
Open the bin folder
Open idea.properties
Add the line:
auto.show.quick.doc=true
The easiest way, at least for me, was:
Ctrl+Shift+A
Type: show document
Show quick documentation on mouse move (set it to ON)
From IntelliJ Ultimate 2018.1.5, aka IntelliJ IDEA 2018.1.5, till 2019.3 , there are actually two options under File -> Preferences:
In Editor > General > Other (section) > Show quick documentation on mouse move - delay 500 ms
Select this check box to show quick documentation for the symbol at caret. The quick documentation pop-up window appears after the specified delay.
In Editor > General > Code Completion (sub-item) > Auto-display documentation in 1000 ms
Select this check box to have IntelliJ IDEA automatically show a pop-up window with the documentation for the class, method, or field currently highlighted in the lookup list. If this check box is not selected, use Ctrl+Q to show quick documentation for the element at caret.
Quick documentation window will automatically pop up with the specified delay in those cases only, when code completion has been invoked explicitly. For the automatic code completion list, documentation window will only show up on pressing Ctrl+Q.
In IntelliJ IDEA 14, it has moved to: File -> Settings -> Editor -> General -> "Show quick doc on mouse move"
In Intellij 2019, I did: File > Settings > Editor > General option Show quick documentation on mouse move.
File-->Settings-->Editor
Check "Show quick doc on mouse"
Now when you put the mouse over a method a tooltip with the documentation will appear. Sometimes the tooltip size is too small and you will have to resize it moving the mouse down to the bottom of the tooltip.
IDEA has "find action":
Open "Help" menu, type "doc", move cursor to "Quick Documentation" it will be highlighted.
Also "find action" can be called from hot key (you can find it in settings->hotkeys)
On mac in IntelliJ Ultimate (trial) 14 I have mine under Settings > Editor > General > Code completion. The tooltip short is F1 on my laptop.
It's called "Autopopup documentation in (ms):"
A note for Android Studio (2.3.3 at least) users, because this page came up for my google search "android studio hover javadoc", and android studio is based on Intellij:
See File->Settings->Editor->General: "show quick documentation on mouse moves",
rather than File->Settings->Editor->General->Code Completion
"Autopopup documentation in (ms) for explicitly invoked completion"
and "Autopopup in (ms)", which has been previously talked about.
I tried many ways mentioned here, especially the preference - editor - general - code completion - show documentation popup in.. isn't working in version 2019.2.2
Finally, i am just using F1 while caret is on the type/method and it displays the documentation nicely. This is not ideal but helpful.
In 2020.1 there is in editor javadocs rendering has been added. Screen shots borrowed from intellij documentation.
On my IntelliJ U on Mac I need to point with cursor on some method, variable etc. and press [cntrl] or [cmd] key. Then click on the link inside popup window which appeared to see JavaDocs
All of the above methods are useful but one basic thing missing you need to have src.zip in your JDK (C:\Program Files\Java\jdk1.8.0_171). I assumed it comes preinstalled but for some reason, it was not present in my installation. Another thing to check is if your project is using the specified (1.8.0_171 in this case) JDK.
The answer is CTRL + P (NOT CTRL + Q)
Someone else posted this answer on JetBrains forum:
The idea is a different IDE. Try to discover its features and try to make the best of it, rather than trying to emulate whatever you used before.
For the most part, Idea has very high usability (much better than Eclipse IMHO) and is streamlined for supporting code editing as best as possible (rather than relying on wizards too much for example).
Javadoc: Ctrl-Q
A quick view of the implementation: Ctrl-Shift-I
Show context: Alt-Q
Show parameters (in a method call): Ctrl-P
Show error description. Ctrl-F1
... plus many more shortcuts to navigate in code and different idea views.
I think it rather nice that you can see just the specific bit of information you are interested in with a simple keystroke.
Have a look at the menus which will also show the possibly modified shortcuts for your keymap.

And, elsandros, in addition to what Stephen writes: Since you seem to be interested in IDEA's keyboard shortcuts, I highly recommend the "Key Promoter" plugin which helps you memorize the relevant shortcuts quickly.
Also very useful is the "Goto Action" feature, invoked by Ctrl-Shift-A. In the popup, you can enter a keyword (e.g. "Javadoc"), and the IDE tells you the available actions matching your search, along with keyboard shortcuts and the containing action groups (which often also give you a clue about how to navigate to the action using the menu).
I'm brushing up my Eclipse RCP skill by trying to enhance my one-year-old side RCP application. This application has one perspective, and this perspective has 3 views, and I'm adding another view into the same perspective. To add this new view, I added it in the MANIFEST.MF file under Extensions tab and created the Java file for it.
When I run it as an Application, it works. I see all 4 views in the application. But, when I run it as a Product, that new view is missing. It almost seems like the new view is not registered in the Product. There's no error in the console log either. I think I must be missing a step here, but I can't seem figure out here... pretty frustrating!
Note: The views are added into the perspective programmatically (in Java code), not through MANIFEST.MF file. I just realized that even when I change the existing view's layout (ex: size, or location), it doesn't get reflected when running as a Product either, but it works when running as an Application... sigh!
Note: I commented out all the code in my perspective class, in another word, all the views are removed from the perspective. When I launch the Product, I'm still seeing 3 views in the application. I'm thinking there's something to do with caching, but I'm just bummed now.
Any helps are greatly appreciated here! Thanks much,
Okay, after aimlessly clicking around, I figured out the solution. The workspace data needs to be cleared to pick up changes from the perspective.
To do so...
Right click the product file
Choose "Run Configurations..."
Under "Main" tab, check "Clear" checkbox and "workspace" radio button.
Run it.
Hope this will save some of you from troubles.
I've been bitten by this a couple of times until I figured out the easiest workaround: it's sufficient to reset the perspective. There are two ways to achieve this:
Right-click on your perspective in the perspective selector bar at the top right and click on Reset.
Switch to your perspective and then go to Window | Reset perspective....
After that, the changes to your perspective should be picked up.
