It is seem that GremlinServer version is too high. GremlinServer 3.3.1 have a dependence with orientdb-gremlin 3.0.20.
newest develop branch is dependence GremlinServer 3.4.0 and orient 3.1.0，I can not build with GremlinServer 3.3.1. So, Once I downgrading GremlinServer to 3.3.1, all error are disappear

This looks like a case similar to this one: https://github.com/orientechnologies/orientdb-gremlin/issues/174. ODB version 3.0 supports TP gremlin server version 3.3.0. In ODB 3.1.0 the supported TP version is 3.4.6. Unfortunately, if the versions do not match, then you might see issues like the one you got.
