How did you run the "gcloud app deploy" command, what parameters?   gcloud app deploy [CONFIGURATION_FILES] is expected. What configuration files did you indicate? 

The recommended deployment procedure uses Maven. 

Error message seems to point out that you use an older version of Guava, namely dating from 2014. A more recent version might be of help in this context.
