In Maven how to exclude resources from the generated jar?

To exclude any file from a jar / target directory you can use the <excludes> tag in your pom.xml file.

In the next example, all files with .properties extension will not be included:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <excludes>
                <exclude>*.properties</exclude>
            </excludes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>
