Animal Sniffer doesn't scan dependency library

[orangesgithub]

I want to use Animal Sniffer Maven Plugin (V1.19) to scan the classes from dependencies against the generated signature. Below is the maven configuration. But actually the the dependency classes are not scanned, what is the problem? // Note that the code in current project can be scanned.

    <dependencies>
        <dependency>
            <groupId>XXX</groupId>
            <artifactId>XXXXX</artifactId>
            <version>XXXX</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>animal-sniffer-maven-plugin</artifactId>
                <version>1.19</version>
                <configuration>
                    <signature>
                        <groupId>XXX</groupId>
                        <artifactId>signature</artifactId>
                        <version>0.0.1-SNAPSHOT</version>
                    </signature>
                    <ignoreDependencies>false</ignoreDependencies>
                    <ignores>
                        <ignore>com.sun.*</ignore>
                        <ignore>sun.*</ignore>
                        <ignore>java.*</ignore>
                    </ignores>
                    <includeDependencies>
                        <dependency>*</dependency>
                    </includeDependencies>
                </configuration>
            </plugin>
        </plugins>
    </build>
