Embedded error: Could not create task or type of type: scriptdef.

Hi 

I'm trying to use a non-standard Ant task (scriptdef), and it's giving me 
this error:
Embedded error: Could not create task or type of type: scriptdef.

The dependency jar is in my pom:
                <dependency>
                        <groupId>bsf</groupId>
                        <artifactId>bsf</artifactId>
                        <version>2.3.0</version>
                </dependency>


Any help is highly highly appreciated.
Thanks
