How do I clear search results in Eclipse? - java

In Eclipse, a file search for a text pattern results in a yellow arrow at the far left margin for each line containing a match. How can I clear these markers? They obscure any breakpoints I wish to place at those lines.

Open the search view: Window -> Show view -> Other -> General -> Search
Click the "clear all" button (it looks like 2 crosses),
Just to add, on mouse over of the two crosses, tool tip reads as Remove All Matches, and to make it more clear,

How can I search and replace a String in all files of my current project?
Let's say I have the string "/sites/default/" now I want it to be "/public/sites/default/", but there are almost 1000 files.
Goto "Search"->"File" from menubar at the top left
Enter text, file pattern and projects
Click "Replace..." button at the bottom
Enter new text click ok
Voilà...
Depending on the file type you are focused on, Ctrl+H will open up different types of search screens.
A more consistent hotkey would be using the Alt method: Tap Alt, then A, then F.
Efficient Order of Operations:
Ctrl+C the text you want to do the replacing (if available)
Highlight the text you want to be replaced
Tap ALT, then A, then F. Brings you to File Search. The selection from (2) will auto-fill the search box
In the “File name patterns” input box, type in “.java” for replacing all Java files or type in "" to replace in all files
Click “Replace…”
Ctrl+V (Paste). Or type in the value you want to do the replacing
Enter

Use Ctrl+H for opening Eclipse search dialog, select appropriate search tab and select "Replace..." to get you to the "Search and replace" dialog
Strange but it is a two step task:
Search what you want
In the search tab right click and select replace , or replace all:

Tonny Madsen said it right, but sometimes this is too simplistic.
What if you want to be more selective in your replacements since not all replacements are correct for what you're trying to do?
Here's how to get more granularity to do the replacements only in certain folders, files, or instances:
First, do like he said:
Click Search --> File... OR press Ctrl + H and choose the "File Search" tab.
Enter text, file pattern and choose your Workspace or Working Set.
Then:
Click Search
When your results come up, make some folder, file, or instance selections by Ctrl + clicking on the ones you'd like to select. Ex: here's my selection. I've chosen 3 instances, 1 file, and 1 folder:
Now, right-click on your selection and go to --> Replace Selected.... Here's a screenshot of that:
Enter what you'd like to replace it "With". In my case you can see it says it is "Replacing 190 matches in 4 files". Now click OK.
Voilà!

ctrl + H will show the option to replace in the bottom .
Once you click on replace it will show as below
There is an option in search => file and shortcut is Ctrl+H. Go for further refer follow link. This is work fine with Eclipse Neon
Is there a way to find/replace across an entire project in Eclipse?
If you want to replace two lines of code with one line, then this does not work. It works in notepad++. I end up open all files in notepad++ and replaced all.
Ctrl+F gives me Find/Replace dialog box.
Or you can,
First Alt+A
Next Alt+F
Then press on Replace button.
If non of them worked:
Goto -> Window -> Preferences -> General -> Keys and search for replace then you will see binding for Find and replace. In the bottom of that window, you can add your key to Binding text box. There you can add or edit any keys as shortcut.
I have tried the following option in Helios Version of Eclipse.
Simply press CTRL+F you will get the "Find/Replace" Window on your screen

Eclipse - Only Auto-Indent On Typing

Is it possible to have Eclipse only indent new lines when you start typing code? For example, hitting enter brings the text cursor back to the left-hand margin, but starting to type on that line would tab it to the appropriate indentation?
I currently strip trailing whitespace on save, but that's not really the behavior I want.
Eclipse can automatically add/remove indentation in some cases (one of them is when line is empty). For that you need to enable auto formatting on save action.
Go to Window -> Preferences -> Java -> Editor -> Save Actions check both Perform the selected actions on save and Format source code.
Then make sure that currently used formatter doesn't indent empty lines.
Go to Window -> Preferences -> Java -> Code Style -> Formatter click Edit... button. In the Indentation tab un-check (if checked) Empty lines under Indent section.

Eclipse - Search arrow icons

Is there any of disabling the yellow arrow that shows up when you perform a search in eclipse ? I was debugging my program earlier and i couldn't find my breakpoints, only to realize a couple of minutes later that they were being hidden behind eclipse arrows.
I know that the arrow goes away when you remove the matches from the search view, but is there a way of completely disabling the arrow from being shown ?
EDIT: Same goes for the green triangle for #Override
Go to: Preference -> General -> Editors -> Text Editors -> Annotations then select the Annotation you would like to remove from the list of annotation types. Uncheck the 'Vertical ruler' checkbox and apply the changes.
Hope this helps.

Checkstyle : always receive File contains tab characters (this is the first instance)

I'm using Checkstyle for Java in Eclipse IDE. I don't know in every java file, at second line, I always receive warning in Checkstyle : (although I'm pretty sure that I don't press tab key)
File contains tab characters (this is the first instance).
public class Percolation {
private boolean[][] grid;
...
}
When I have typed : public class Percolation {, press enter, Eclipse will make an indent for me, after that, I type private boolean[][] grid;. But, I still receive this warning.
Please tell me how to fix this. (I don't want to turn off this warning, because this is a must. Another people will check again my file).
Thanks :)
step 1 In eclipse, Preference > Java > Code Style > Formatter. Edit the Active profile.(If you don't wish to edit the built-in profile , create a new profile). Under "Active profile:" there is a drop down dialogue box .. beside it, click "Edit..." which opens up the edit dialog box. Under the "Indention" tab, you'll find Tab Policy. Change the Tab Policy from Mixed to Space only & apply the changes.
step 2 Back to your Eclipse Perspective, navigate via the menu bar: Source > Format Element (not "Format") and save.
Run checkstyle you won't find "File Tab Character: File contains tab characters (this is the first instance)." warning anymore.
To visualize the difference by enabling whitespace character that you'll find in tool bar.
In eclipse, go to Preferences > General > Editors > Text Editors
and check the box for "Insert spaces for tabs". Then it will indent with spaces instead of tabs.
another possibility is find and replace:
- copy a tab
- Got to Find and Replace Window
find: paste the tab
replace: type 4 whitespaces (or number of whitespaces a tab consists of)
-> replaceAll
For Java code:
step 1 In eclipse, Preference > Java > Code Style > Formatter. Create a new profile and initialize it with default profile. There is a drop down dialogue box .. beside it, click "Edit..." which opens up the edit dialog box. Under the "Indention" tab, you'll find Tab Policy. Change the Tab Policy from Mixed to "Space only" & apply the changes.
step 2 Correct Indentation of your code by ctrl+I. It will replace Tab with Space.
To fix this Navigate to Preferences > Java > Code Style > Formatter.
Then click on New > give name for the formatter > click on ok.
Once you complete this step, on the automatically popped up window which is the formatter you created, click on indentation > tap policy > select space only.
Or if you come back later time you could click on edit and follow the same step.
in the indentation size I prefer to put 4 > click apply and close.
After that right click on the class file you want to format > source > format.
This will cause the indentation to be spaces instead of tabs.
I was also facing the problem but I got the solutions.
Step 1 : Go to Window > Preferences > Checkstyle.
Step 2 : In the right side You will see the Global Check Configurations. There you will find that Two configurations are available. Select the configuration with Eclipse and click on Set as Default button and click on OK.
Hope this will solve your problem.
For Java Editor
Click Window » Preferences
Expand Java » Code Style
Click Formatter
Click the Edit button
Click the Indentation tab
Under General Settings, set Tab policy to: Spaces only
Click OK ad nauseum to apply the changes.
For other editors refer here How do I change Eclipse to use spaces instead of tabs?
Simply fixed that style issue (triggered by scalaStyle) by removing TAB with SPACE indent :)

Eclipse: How do you change the highlight color of the currently selected method/expression?

In eclipse, when your cursor is placed on a method (or other things), other places the method exists are highlighted. I'd like to change the color of this highlight, but after scouring the eclipse preferences many times in all 3 places, I have yet to find it.
Any of you Eclipse gurus know where to find this option?
After running around in the Preferences dialog, the following is the location at which the highlight color for "occurrences" can be changed:
General -> Editors -> Text Editors -> Annotations
Look for Occurences from the Annotation types list.
Then, be sure that Text as highlighted is selected, then choose the desired color.
And, a picture is worth a thousand words...
(source: coobird.net)
(source: coobird.net)
For those working in Titanium Studio, the item is a little different: It's under the "Titanium Studio" Themes tab.
The color to change is the "Selection" one in the top right.
1 - right click the highlight whose color you want to change
2 - select "Properties" in the popup menu
3 - choose the new color (as coobird suggested)
This solution is easy because you dont have to search for the highlight by its name ("Ocurrence" or "Write Ocurrence" etc), just right click and the appropriate window is shown.
If you're using eclipse with PHP package and want to change highlighted colour then there is slight difference to above answer.
Right click on highlighted word
Select 'Preferences'
Go to General > Editors > Text Editors > Annotations. Now look for "PHP elements 'read' occurrences" and "PHP elements 'write' occurrences". You can select your desired colour there.
right click the highlight whose color you want to change
select "Preference"
->General->Editors->Text Editors->Annotations->Occurrences->Text as Hightlited->color.
Select "Preference ->java->Editor->Restore Defaults
in my case (Eclipse IDE 2021-06), dark theme, the issue was with the background color of "C/C++ Write Occurrences".
On each click over a variable being written in the code, the editor highlights all occurrences of that variable.
You can find this setting here:
General -> Editors -> Text Editors -> Annotations
and then select 'C/C++ Write Occurrences'.
And finally change che Color property.
