How to tell flatten-maven-plugin:1.0.1 leave ${project.basedir} not to resolve it with a fix string when produce flatten pom

Question

I'm using flatten-maven-plugin:1.0.1 to solve my dependency versions.

But it introduces another problem.

In my pom I have using

<dependency>
    <groupId>org.cryptix</groupId>
    <artifactId>cryptix-jce-provider</artifactId>
    <version>1.0.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/libs/cryptix-jce-provider.jar</systemPath>
</dependency>

The flattened pom replaced the ${project.basedir} with fix string and it is not portable when other people using the flattened pom.

<dependency>
    <groupId>org.cryptix</groupId>
    <artifactId>cryptix-jce-provider</artifactId>
    <version>1.0.0</version>
    <scope>system</scope>
    <systemPath>/var/lib/jenkins/workspace/dsd-content-store-springboot-   spring-consul/store-view-springboot/store-view-server/libs/cryptix-jce-provider.jar</systemPath>
</dependency>

Can you please let me know if I can configure the flatten-maven-plugin to leave the property alone and not resolved it.
