Agile averify BUILD FAILED without specifics why

When I run averify on my sandbox the averify report is as shown below.

Can somebody tell me some of the possible reasons the BUILD FAILED?

My averify.properties is as follows:

averify.dest.jdbc.url = jdbc:oracle:thin:myhost:1521:agile9
averify.dest.jdbc.driver = oracle.jdbc.driver.OracleDriver
averify.dest.db.user = agile
averify.dest.db.password = EC870C8D66E90395
averify.dest.tns.name = agile9
