Exclude target folder from search results in Eclipse

Question

I was wondering if it's possible to exclude target folder from eclipse quick search :

Ctrl+Shift+R

If anyone knows how to do that, please advise.

Update: I am using Maven 2, and M2E , WTP Eclipse plug-ins.

Are you working in the context of Maven 2/3? Are you using any additional plugins? Do you have an example where a resource is in a target and non-target folder? — mliebelt, Nov 21 '11 at 14:25

Mark the "target" folders as "derived" resource from the properties screen of those folders (this option is next to read only and archive property).
In the quick search (Ctrl+Shift+R) screen press the arrow in the top right corner and untick "Show derived resources".

Then those target-files will not be considered in the quick search anymore.

Go to Add Resource Filter preferences dialog:

Then fill the options:

Filter type:

The best solution with no doubt. – shimatai Sep 15 '16 at 16:42

Our project is rather big and consists of three working sets with more than 200 subprojects which even change depending on the branch you're working on. Not a good solution for me to edit every single project. – Arigion Jul 05 '17 at 07:10

If you have imported your parent maven project all files are found twice (once with project path and once with parent project path). If you "Add Group - Exclude all, Files and Folders" it won't happen. – T3rm1 Feb 13 '18 at 14:43

You can install AutoDeriv plugin from Eclipse Marketplace or http://nodj.github.io/AutoDeriv/. It allows you to create either global(workspace) or per-project .derived files in which you can specify which files/folders should be marked as derived.

Here's a sample config file (taken from plugin's homepage):

# set the 'target' and 'ext' folders as derived
target
ext
# but don't affect the 'keep' sub-folder
!target/keep
# all files with a '.dep' extension are generated
*.dep
src/include/version.h # this specific file is also generated.

I'm, using that "AutoDeriv" plugin now and it correctly sets all the "target" folders as derived, but when I press ctrl+shift+R I'm still getting suggestions from files that are inside "target" folders (even from those of other projects that the current one sees)... And yes, I've unchecked the "show derived resources" flag... :( – nonzaprej Nov 26 '19 at 15:28
