How to show only (src) files not (target) files by Eclipse shortcut (cntrl + alt + R)?

Question

By using Eclipse shortcut (CTRL+Shift+R)
Will show both (src) files and also (target) files.
Like that

The problem is that
Some times by mistake
I select the target file then i update my changes
After build i will NOT see the new changes !!
Thats because i update the wrong files (target)

So any idea
How to show only (src) files not (target) files by Eclipse shortcut (CTRL+Shift+R) ?

Answer 1

The quick and (dirty way) :

Right click on a target folder(s)
Go to folder(s) properties,
Mark folder as Derived like that.
Derived entities are excluded from searching by default like that.

The (safe way) :

By create a working set
That include only those entities you want searched and search only within that working set.
In our case will include ALL without target folder(s).

Answer 2

In the project-settings on java build-path you'll find on source a checkbox like this:

Disable it, for not getting files which are in the target folder to your view. So you will not find it by Eclipse shortcut (CTRL+Shift+R)
