Application Development Software

I try to run the script created with workshop and I got error. Any idea what is mdimport task is doing?
There is absolutely NO documentation about it. Any help would be apprecated.

*** The commEnv file was executed before running the script.


Part of the generated build script:
<echo message="${workspace}"/>
<echo message="${project.dir}"/>
<echo message="${echo.metadata}"/>
<mdimport workspace="${workspace}" pjdir="${project.dir}" echo="true">
</mdimport>

Buildfile: build.xml
init.env:
check.versions:
init.typedefs:
init:
[echo] C:\workshopworkspace

BUILD FAILED
C:\app\build.xml:80: java.lang.NullPointerException

Details with ant debug:
