Presently when Qlik Replicate requires to connect to Google Big Query (BQ), Google SDK needs to be installed on the Replicate server.
The concept of installing Google SDK on Replicate server is wrong (for that matter on any servers where development of code is not done) .
Installation of Google SDK, requires connection to internet. Usually from security perspective, Replicate servers are behind Fire walls without internet connection. Even the archived Google SDK requires internet connection (The google document says that you can install behind firewall, but it is not true. it requires internet connection)
Please remove dependency of installation of Google SDK on Replicate Server.
Further the required files for BQ should be part of Qlik Replicate installation.
This is due to the fact that Version dependencies of Qlik Replicate BQ endpoint is very high on Google BQ jar versions
