DevOps / Gradle8 Interview Questions

What are plugins in Gradle?

A plugin packages reusable build logic — new task types, conventions, extensions to configure — so a project doesn't have to hand-write common functionality like Java compilation or dependency management from scratch. Applying the java plugin, for example, instantly adds standard tasks (compileJava, test, jar) and a conventional source layout (src/main/java, src/test/java).

Plugin TypeExample
Core pluginsjava, application, maven-publish — ship with Gradle itself.
Community pluginsPublished to the Gradle Plugin Portal, e.g. Spring Boot's plugin.
Script/precompiled pluginsCustom, project-specific logic written as a plugin rather than duplicated across build files.

Plugins are what make Gradle build scripts short in practice — most of the actual build behavior comes from applied plugins, and the build script itself is mostly configuration on top of those conventions.

What does applying the java plugin add to a project?
Where are community Gradle plugins typically published?
