Gretty is a feature-rich Gradle plugin for running web-apps on embedded servlet containers. It supports Jetty version 11, Tomcat version 10, multiple web-apps and many more. It wraps servlet container functions as convenient Gradle tasks and configuration DSL.

A complete list of Gretty features is available in feature overview.

You are looking at Gretty's master branch which is for Gretty 4. You also might want to look at the gretty-3.x one which is for Gretty 3. It is still in development and supports older (non-Jakarta) versions of Jetty and Tomcat.
