Integration test: copy adapter files of keycloak

Question

I want to deploy my application in a tomcat server during integration tests. This works fine. I am struggling with copying the keycloak-adapter-core to the folder: \target\cargo\installs\tomcat-8.5.9\apache-tomcat-8.5.9\lib

If I copy the files manually, my application runs. I would like to know how to copy these files automatically. Or find a smart way how to download them to the lib folder directory, before the integration test is conducted.

This is the part of my pom.xml
