`I am working with projects organized hierarchically on disk. For example:

foo-parent
foo-module1
src
resources
foo-module2
src
resources

This structure give 3 projects in Eclipse:

foo-parent
foo-module1
foo-module2

Note that such project layout is quite popular in Maven community.

Now, when resource in foo-module1/src/resources is changed, e.g. using one of Eclipse editors, this same resource is forcefully shown in the package explorer two times, first in foo-module1/src/resources and second in foo-parent/foo-module1/src/resources

This clutters package explorer view and also forcing user to deal with this clutter, basically distracting him form the main task.`

In your case, you will also get each search result twice.

In such a case, I always filter out the foo-module* projects from the foo-parent project. Did you try this?

Lots of people don't know about filters. You can do that via the properties of a project:

Here I have two nested projects but I don't want to show them twice, so in the parent project, I filter out the children of the nested projects so that I still see the placeholder folder, but not the "duplicate" contents. Here's a filter expression which uses regular expressions:

maven-osgi/org.eclipse.orbit.maven.generator/.*|maven-bnd/org.eclipse.orbit.maven.bnd.generator/.*

Thanks. I'll have to try it out.

Could something like that be incorporated into focused mode?
