Apache Tomcat - Using Tomcat libraries with Maven

Tomcat snapshots are located in the Apache Snapshot Repository. The official URL is https://repository.apache.org/content/repositories/snapshots/org/apache/tomcat/

Snapshots are done periodically, not on a regular basis, but when changes happen and the Tomcat team deems a new snapshot might useful.

Stable releases are published to the Central Maven Repositories. The URL for this is

https://repo2.maven.org/maven2/org/apache/tomcat/
