Normally there is a dependency in your project that is depending on servlet-apî.jar

The default behaviour of Maven is that i wiill try to import your dependency + the dependencies of the imported dependency.

If you want to exclude a specific "sub-dependency", you can give maven a configuration like this :

    com.hpsworldwide.mbtrs.switch
    YOUR_DEPENDENCY
    1.0
    
        
            javax.servlet
            servlet-api
        
    

then maven will import YOUR_DEPENDENCY + all YOUR_DEPENDENCY dependencies, but will exclude servlet-api from the dependencies of YOUR_DEPENDENCY.
