Server Tomcat v9.0 Server at localhost failed to start because of com.mongodb.client.MongoDatabase

Question

Tomcat9 server can't start again because this time has below error, I already follow the installation instruction from the official website using 3.12, and also I can't the jar in my classpath.

However, it works previously until now. what other MongoDB dependencies I should add?

I also use Java 1.8 JDK for run time.

Error message below,
