- runtime environment: a set of libraries known to work well together. e.g., the Spring Platform, recommending versions for both Spring and components that work well with Spring.
- deployment environment: Java runtime, application server, ...

In addition Gradle defines <<dependency_version_alignment.adoc#sec:virtual_platform,virtual platforms>>.

...
Type
     Jar (org.gradle.api.tasks.bundling.Jar)
----
--

Let's bring all this together by running through a quick worked example that configures the `bootJar` and `bootRun` tasks of a Spring Boot project:

.Configuring Spring Boot using type-safe accessors
====
include::sample[dir="snippets/kotlinDsl/configuring-tasks-spring-boot/kotlin",files="build.gradle.kts[tags=accessors]"]

* `*:guava`: will let all modules named `guava`, whatever their group, update
* `org.springframework.spring*:spring*`: will let all modules having their group starting with `org.springframework.spring` and name starting with `spring` update

NOTE: The resolution may cause other module versions to update, as dictated by the Gradle resolution rules.

Resolving dependencies::
A plugin uses configurations to find (and possibly download) inputs to the tasks it defines. For example Gradle needs to download Spring web framework JAR files from Maven Central.
Exposing artifacts for consumption::

        return config
    }

    String getProjectName() {
        return config.projectName
    }

    String getDaemonMemory() {
        return config.daemonMemory
    }

    def getParallel() {
        return config.parallel
    }

    def getMaxWorkers() {
        return config.maxWorkers
    }

    @Override
    String toString() {
        return config.projectName

}
