How to exclude directory in Maven in basedir from adding sources to release?

I have parent pom.xml and I have modules there, structure is like this:

pom.xml
module1/
module2/
module3/
resources/
test/
README.adoc

When I want to release this project, I do it like

mvn release:prepare release:perform

What it does is that when I look into sources of parent project (pom.xml project), I can see that sources-release.zip contains all directories including some_resource_dir.

I want to exclude that directory from being in resulting parent sources release zip.

My initial approach was like this in root pom.xml

<build>
    <resources>
        <resource>
            <directory>${project.basedir}</directory>
            <excludes>
                <exclude>tests/*</exclude>
                <exclude>resources/*</exclude>
                <exclude>README.adoc</exclude>
            </excludes>
        </resource>
    </resources>        
</build>

But that fails. The first module1 said that:

Failed to execute goal org.apache.maven.plugins:maven-source-plugin:2.2.1:jar-no-fork (attach-sources) on project module1: Error creating source archive: A zip file cannot include itself -> [Help 1]

How do I get rid of these directories in a resulting sources release zip archive?
