Eclipse file search finds the same file multiple times

Question

In Eclipse I have two maven projects A and B, where A is a parent for B. The directory structure is the following:

A/pom.xml A/B/pom.xml A/B/... 

Then I use File search (Ctrl+H) to find any file in the project B. The search result window shows the file two times with different relative paths:

A/B/<my_file> B/<my_file> 

So, the same file is shown twice. Obviously, the first search result is reduntant. Is there a way to exclude these duplicate search results?

Answer 1

What I personally do to avoid this is marking each module in the parent project as derived (right-click on the folder > properties > Attributes: Derived).

Then when you perform a file search, uncheck "Consider derived resources" (I don't think it is checked by default) and you won't get the A/B/<my_file>.

The only inconvenience is that you must do this for each module, and each time a new module is added.

Answer 2

In an open resource window (cntrl+shift+R), click on the arrow on top-right and check "Filter Duplicated Resources". This worked for me.
