You can also encapsulate the versions of external plugins by composing the build logic using your own <<sharing_build_logic_between_subprojects#sec:convention_plugins,convention plugins>>.

= Understanding Plugins

Gradle comes with a set of powerful core systems such as dependency management, task execution, and project configuration.
But everything else it can do is supplied by plugins.

Plugins encapsulate logic for specific tasks or integrations, such as compiling code, running tests, or deploying artifacts.
By applying plugins, users can easily add new features to their build process without having to write complex code from scratch.

      null
    } catch (e: RuntimeException) {
      // Throws InaccessibleObjectException (added in JDK9) on JDK 17 due to
      // JEP 403 Strongly Encapsulate JDK Internals.
      if (e.javaClass.name != "java.lang.reflect.InaccessibleObjectException") {
        throw e
      }

[[sec:convention_plugins]]
== Share logic using convention plugins

Gradle's recommended way of organizing build logic is to use its plugin system.

We can write a plugin that encapsulates the build logic common to several subprojects in a project.
This kind of plugin is called a *convention plugin*.
