Such a library dependency can be added to a source set associated with the `executable` component:

=== Example: Providing a library dependency to the source set

[source.multi-language-sample,groovy,indent=0]
.build.gradle
----

. Read the <<#changes_5.0, Upgrading from 4.10>> section and make any necessary changes.
. Try to run the project and debug any errors using the <<troubleshooting.adoc#troubleshooting, Troubleshooting Guide>>.

In addition, Gradle has added several significant new and improved features that you should consider using in your builds:

* Elements in the `tasks` and `configurations` containers
* Elements in <<kotdsl:containers,project-extension containers>> (for example the source sets contributed by the Java Plugin that are added to the `sourceSets` container)

For the main project settings script:

* Project extensions and conventions, contributed by `Settings` plugins, and extensions on them

The deprecated `build-scan` plugin application method has been removed from the Kotlin DSL.
Use the `gradle-enterprise` method instead.

==== Configuration extension methods removed from Kotlin DSL

The Kotlin DSL added specialized extension methods for `NamedDomainObjectProvider<Configuration>` that are available when looking up a configuration by name.
