Artifact lose maven dependency scope=system

I have a webapp-project with a local dependency

        <!--  Captcha -->
        <dependency>
            <groupId>com.google.code</groupId>
            <artifactId>kaptcha</artifactId>
            <version>2.3.2</version>
            <scope>system</scope>
            <systemPath>${basedir}/../lib/kaptcha-2.3.2.jar</systemPath>
        </dependency>

When I update my pom.xml with other dependency, my webapp-artifact lose the captcha dependency.


Thanks, in advance.

ps. I use intellij 10.5.2
