the issues on "run the reuters extraction code from the examples directory"

Dear All,

I am a new user of Mahout library, and trying to learn Mahout by following
the examples given in "Mahout in Action".  Following the book, I tried to
run the reuters extraction code from the examples directory as follows:

/mahout/trunk/bin% mvn -e -q
exec:java-Dexec.mainClass="org.apache.lucene.benchmark.utils.ExtractReuters"-Dexec.args="reuters/reuters-extracted/"



the system gives the following error message

+ Error stacktraces are turned on.
[ERROR] BUILD FAILURE

Can you let me know how to analyze this error, and how to fix it? Any hint
will be highly appreciated. Thanks.

Huai

Can you provide more of the actual failure? this doesn't say anything by itself.
