I really like IDEA's code formatting, but how do I get it to reformat all the code in a particular project without going through each file? I've found the option to tidy / optimise imports on code before committing it to subversion which is great, but it only seems to apply to files that have otherwise been modified (which is sensible in the majority of cases!)
Is there a way to auto-format all the source files in a project without going through them all by hand?
In the tree-structure, right click on the folder you like to reformat, choose "Reformat code" from the menu.
Choose the "whole project" radio button instead of the individual file when you ask to reformat.
Just be aware of one problem: If you're working on a larger project with other developers who don't conform to your style, and you're using IntelliJ to transform all their code every time you edit it, you might be causing a problem with your version control system. It will long a huge volume of changes when you check in, and few of them will have anything to do with changing functionality. Better to conform to the group style in that case.
According the iDea: Editor basics documentation:
You can use the shortcut Ctrl+ALT+L (Windows/Linux) or ⌥⌘+L (MAC OS X) and select the Rearrange entries option to reformat the code in the current file or reformat a module or directory (after selecting more than one file).
You can also Right-click a module, file, or directory from the context menu and select Reformat Code and also select the Rearrange entries option.
You can also optimize the imports of your files by selecting the Optimize imports option.
Is some Linux versions the shortcut Ctrl+ALT+L can lock the screen, so you will need to Right-click a file or directory from the context menu and select Reformat Code and also select the Rearrange entries option.
This works for most of the Jetbrains IDES (iDea, PyCharm, WebStorm, RubyMine, and so on.)
"CTRL + ALT + L" work only windows.
"CTRL + ALT + L" is Ubuntu Lock screen shortcut key so its not working for this.
Try ,
Right click on the folder you like to reformat, choose "Reformat code" from the menu or click "Code" button on navigation bar in top, choose "Reformat code"
Thank you

When I create a new Java project or open an existing one, IntelliJ doesn’t highlight any of the text nor does it suggest anything. All the code is 1 single color. I’ve marked my src file, made sure power safe is off, made sure highlight is enabled, and even reinstalled IntelliJ CE. I’ve also disabled all plugins. Any suggestions is appreciated.

Your screenshot shows that the file is not recognized as a java source file.
Go to Preferences -> Editor -> File types
Scroll down in the list of Recognized File Types and click Java.
In the list of registered patterns make sure it shows *.java.
Also ensure the file is not marked in the Ignore files and folders section at the bottom of this preferences panel. Perhaps you added it by accident (with some shortcut).
Also, while reinstalling IntelliJ, you have probably imported your previous settings. With it, you inherited this issue.
If this doesn't help, please share a screenshot of your project/module structure and setup.
Last but not least, try to create the file using the context menu. E.g. try to right click on your src folder and select new and select Java class or Package from the options. Would be good to check anyway, to see if these are valid options. If they do not appear here, it indicates the project setup is erroneous.
Solved! Thanks to #yole I did the following 'make sure that the *.java extension is listed in "Registered patterns" for the Java file type in Settings | Editor | File Types".
There is no syntax highlighting in java files in my eclipse..This happened all of a sudden..Not sure why..
This is how it is looking now..
As mentioned in other posts..i tried to change the color from preferences window and there is nothing when i type java..something really messed up...
AAny suggestions..
Update:
It seems Java plugin is not installed..as per the below screeenshot
And when i try to install java plugin it says new version is already installed as per the below screenshot
Closing the file's tab and re-opening it fixed it for me.
(I actually closed all the tabs...)
I faced the same issue all of a sudden after a commit/update project operation.
The point is, default editor of Eclipse has changed somehow and we have to set it back to normal.
Try the below method,
1. Goto Windows -> Click Preferences
2. From the Preferences window goto General -> Editors -> Click File Associations
3. You can choose the default editor for *.java files here
When I first opened Preferences, 'Text editor' was set as the default editor for .java files and then I changed it back to 'Java Editor'.
Now it works perfectly fine.
You probably have a corrupt installation or you have recently installed a corrupt plugin.
The following steps might help.
In your Install window,
view your "already installed" plugins.
select the "Installation History" tab.
select a previous stable configuration
Click the "Revert" button
TLDR; open another workspace, then come back to the original workspace.
Ok this is odd, but for me, all the highlighting suddenly went away for Java files. I explored all of these ideas here, with no effect. I created a new workspace, planning to move everything to it. I realized that can be a pain to move many projects over, so I went back into the original workspace to look at some settings, and poof - the highlighting was working again.
I have one java class file like a text editor.
I tried following,
Select the respective java class file from eclipse.
Right click on the file and mouse hover on "Open with".
Select java editor.
Now its works.
Eclipse does not highlight matching variables for me:
I've already tried to change "Mark occurrences" via
Window -> Preferences -> Java -> Editor -> Mark Occurrences
but it didn't work. I am not sure why this is not working while others
have been able to fix the problem.
Can anyone tell me how can I set highlighting matching variables?
Looking for same variables with my eyes really bothering me too much.
Try:
window > preferences > java > editor > mark occurrences
Select all options available there.
Also go to:
Preferences > General > Editors > Text Editors > Annotations
Compare the settings for 'Occurrences' and 'Write Occurrences'
Make sure that you don't have the 'Text as higlighted' option checked for one of them.
This should fix it.
Alt + Shift + o
Will solve your problem and agree with #Korhan Ozturk as well :)
This is known as Toggle Mark occurrence (Alt + Shift + O), Means will highlight all occurrence of focused variable.
Same thing can be achieved from tool bar as follows
In same tool bar there is another switch if you turn that on you will see complete path for opened file, That is Breadcrumb
there are some more very useful switches like word wrap, Show white Characters just after toggle mark occurrence
There is a bug in Eclipse Juno (and probably others) but I have a workaround!
If you have already checked all the configurations mentioned in the top answers here and it's STILL not working try this.
To confirm the problem:
Select a variable
Notice the highlight didn't work
Click away from eclipse so the editor loses focus.
Click on eclipse's title bar so it regains focus, your variable should be highlighted.
If this is happening for you, you must close ALL of your open files and reopen them. This bug seems to also make weird things happen with Ctrl+S saving of an individual file. My guess is that something is happening whereby internally eclipse believes a certain file has focus but it actually doesn't, and the UI's state is rendered as though a different file is being edited.
Edit: If it's STILL not working, you might need to restart eclipse, but if you don't want to, try selecting the item you want to see occurrences of then disable and re-enable the Mark Occurences Toggle button.
The only that worked for me was:
Java > Editor > Mark Occurrences:
Check "Mark occurrences of te selected element in the current file."
... and maybe all the ones below.
Using Alt + Shift + o
It works for me!
For others running into this without any of the above solutions working AND you have modified the default theme, you might want to check the highlight color for occurrences.
Preferences > General > Editors > Text Editors > Annotations
Then select Occurrences in the Annotation Types, and change the Color Box to something other than your background color in your editor. You can also change the Highlight to a outline box by Checking "Text as" and selecting "Box" from the drop-down box (which is easier to see various syntax colors then with the highlights)
I wish I could have read the response by #Ján Lazár.
In addition to all the configurations mentioned in the accepted answer, below setting solved my misery:
For large files the scalability mode must be turned off. Enabling scalability mode will disable reference highlighting.
PS: #Rob Hruska It would be great if this point is added in the accepted answer. Most of the readers do not bother to read the last response.
For PHP you can set
window > preferences > PHP > editor > mark occurrences
Please check first checkbox (Mark occurrences of selected element in the current file)
And also check
Preferences > General > Editors > Text Editors > Annotations
'Occurrences' and 'Write Occurrences' with different style and color
If highlighting is not working for large files, scalability mode has to be off.

Java - Editor - Mark Occurrences
Eclipse Java EE IDE for Web Developers.
Version: Photon Release (4.8.0)
maybe because it not supports code highlights inside scriplets. not sure though.
You can try using one of the eclipse plugin like 'glance search' which works great.
Here's a link for that-
http://code.google.com/p/eclipse-glance/
I just unchecked all, applied, checked all again, applied and it worked :) hopefully helps others.
Eclipse Toolbar > Windows > Preferences > General (Right side) > Editors (Right side) > Text Editors (Right side) > Annotations (Right side)
For Occurrences and Write Occurrences, make sure you DO have the 'Text as highlighted' option checked for all of them. See screenshot below:
I was having the same issue and the "make occurrences" and "annotations" solutions above did not help. If you are using Maven, I had to convert the project to a Maven project (right click on it in the Package Explorer and go down to configure), then build the project. Then the syntax coloring and highlighting worked correctly.
This is what worked for me (credit to YardenST from another thread):
Instead of double clicking file when opening, right click on file -> Open with -> Java editor
In Scala IDE click on this button in the toolbox to activate Mark Occurrences (off by default).

Sometimes problems in your project build path can cause this, make sure you resolve it first, in my case the prolem was :
And when fix it highlights come back.
I had this issue with Eclipse Mars for PHP developers, 64 bit edition for Windows. I now discovered that highlighting works out-of-the-box with the 32 bit version. Even with a fresh download of the equivalent 64 bit build, highlighting does not work. So I will switch back to 32 bit (this is actually not the first problem I observe with Eclipse 64 bit).
Edit:
I thought this was the solution, so I installed the 32 bit version in C:\Program Files (x86) and set a shortcut in the "Start" menu. When I started Eclipse from there, highlighting again ceased to work. I now got it working again by deleting the .metadata directory in the workspace (i.e. resetting the workspace settings) and re-importing the projects.
Just curious if there's a setting somewhere in Eclipse to keep blocks of code collapsed when the class is opened? It's just I'll collapse methods then when the class is re-opened, everything is expanded.
Thanks
In Windows > preferences:
Java > editor > folding: check all, click apply & then OK.
Maybe this helps: Ctrl + Shift+ NUM_KEYPAD_DIVIDE collapse all methods in a java class.
Source
Yes . From the eclipse official documentation :
You can specify which regions are folded by default when an editor is
opened. Have a look at the Opens the folding preference page Java >Editor > Folding
preference page to customize this.
Just click all the checkboxs .Then whenever a .java file is open in the java editor , everything will be collapsed.
Not sure if this options is the new feature for eclipse indigo version (3.7) , so you may have to update your eclipse to indigo if you use older version but cannot find this option.
I'm not aware of a solution, but let me tell you how I work - maybe this is a solution for you as well:
Enable "Only show the selected Java element". The editor will only show the element (method) you selected (see screenshot).
While editing a file use either the Outline view or CTRL + O to navigate through the class file.
Btw: I disabled all folding options as the above approach just works best for me. Sadly, I'm not aware of a shortcut to enable/disable the "Only show the selected Java element".
Yes, you can set the options what to fold on file open.
You can find it at Settings->Editor->Folding
It features a resonable selection of folding options.
Wouldn't it be nice to just do a keystroke and have eclipse organize all imports in all java classes instead of just the one you are looking at? Is this possible? Is there a keystroke for it?
Select the project in the package explorer and press Ctrl + Shift + O (same keystroke as the single class version). Should work for packages, etc.
You can edit the clean up options on save to make it organize imports. That way all of your imports will always be organized.
In eclipse 3.4 just go into Window - Preferences. In the tree view look under Java -- Editor -- Save Actions.
This is how I keep my imports organized all of the time.
For Eclipse Helios, open the "Project Explorer" view, clic right on your src folder, go under the source menu, and clic "organize imports" that should work for all your project.
or just hit the combination Ctrl + Shift + O on the src folder.
If you want to run save actions against a whole project you can right click on the project, then choose Source and then Clean Up...
I have Leadbolt ads in my Android app. On every Leadbolt version, Leadbolt force me to re-update the name of the java import. For example, in my app it was :
import com.kwswsuyruzouggmtbzxb.*
Then on the update they gave me a new package with the name:
import com.izwevyqazy.*
And therefore, I have to make a change from the older name to the newer name on around 20 or more of java source code files. So, what I did is to re-organize the imports using this way in Eclipse I.D.E.:
Select in your application, the package name, the one directly under the folder "src" in your project folder.
Right click the package name and select "Organize Imports"
Please don't forget to change the names too in the AndroidManifest.xml; otherwise, your app will crash.
For mac you can use Cmd + Shift + O. Alternatively, you can do it through the menu: Source -> Optimize Imports
You can run this on individual files, or for each source folder. The option is greyed out if you try it at the project level of the project explorer. So you may have to do it a couple time if you have a bunch of modules and source folders. :)
