Maven Compile cannot find jars from rt.jar

Question

i have the following dependency in my app as I need some classes from rt.jar.

    <dependency>
        <groupId>com.sun</groupId>
        <artifactId>rt</artifactId>
        <version>1.5.0_06</version>
        <scope>system</scope>
        <systemPath>${env.JAVA_HOME}/jre/lib/rt.jar</systemPath>
    </dependency>

I actually did mvn clean compile -X to print all debug info. It looks like it can identify the location on -classpath but always complains the the package doesn't exist during build failure.

Is there something I need to configure specifically to add this thing as part of my build?
