No result when only performing coreference resolution by command line

[sophiayyya]

I use this command to do coreference resolution, but I don't get any result besides the initial sentence.

mvn exec:java -Dexec.args="--operation COREF --output CMDLINE --corefformat DEFAULT --input FILE input.txt" -Dconfig.file="../conf/graphene.conf"

############
Name: output_coref_input.txt ?
The woman reading a newspaper sat on the bench with The woman reading a newspaper's dog .

No coreference spans are found.
What's wrong with this command for coreference resolution?
