Maven and Gradle share a common approach of extending the build through plugins.
Although the plugin systems are very different beneath the surface, they share many feature-based plugins, such as:

* Shade/Shadow
* Jetty
* Checkstyle
* JaCoCo
* AntRun (see further down)

Why does this matter? Because many plugins rely on standard Java conventions, migration is just a matter of replicating the configuration of the Maven plugin in Gradle.
