The solution
The dependent use of servlets is introduced in the pom.xml file


Change after

add scope tags, and the values is provided (only role in the compilation and testing, and at the same time not pass)
The scope label specifies the range of values
compile
The default scope, which means that all Dependencies can be used throughout the lifecycle. Furthermore, these dependencies are passed to the projects on which they depend. Applies to all phases and will be released along with the project
provided
Similar to compile, but indicating that dependency is provided by JDKs or containers, such as Servlet APs and some Java EE APIs. This scope can only be used during compilation and testing and has no transitivity.
runtime
Dependency does not apply at compile time, but does apply at run and test times, such as JDBC drivers, for the run and test phases.
test
Indicates that dependency is applied at test time, not at run time. Used only during testing, to compile and run test code. Will not be released with the project.
system
Similar to Provided, but provided in the system as an external JAR, Maven does not look for it in a repository.
