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 <https://cloud.google.com/appengine/docs/standard/java/tools/uploadinganapp#using_maven_recommended> uses Maven. Error message seems to point out that you use an older version of Guava <https://mvnrepository.com/artifact/com.google.guava/guava>, namely dating from 2014. A more recent version might be of help in this context. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
