This plugin will then expose the link:{javadocPath}/org/gradle/api/plugins/catalog/CatalogPluginExtension.html[catalog extension] that you can use to declare a catalog:

.Definition of a catalog
====
include::sample[dir="snippets/dependencyManagement/catalogs-versionCatalogPlugin/kotlin",files="build.gradle.kts[tags=catalog_spec]"]

Typically, this happens if you tried to import a catalog using `from(files("some-catalog.txt"))`.

Currently Gradle only supports TOML version catalogs.

To fix this problem, either import a TOML file, or use the `Settings` API to declare your catalog.

[[catalog_file_does_not_exist]]
== Catalog file doesn't exist

This error indicates that you tried to import a catalog file, but the file doesn't exist.

== Version Catalog

Version catalogs provide a way to centralize your dependency declarations in a `libs.versions.toml` file.

The catalog makes sharing dependencies and version configurations between subprojects simple.
It also allows teams to enforce versions of libraries and plugins in large projects.

The version catalog typically contains four sections:

        'dependency-version-catalog:invalid-dependency-notation' : 'Dependency version catalog problem',
        'dependency-version-catalog:reserved-alias-name' : 'version catalog error',
        'dependency-version-catalog:catalog-file-does-not-exist' : 'version catalog error',
        'dependency-version-catalog:toml-syntax-error' : 'Dependency version catalog problem',
