Let's imagine that the consumer requires _instrumented classes_ from the producer, but that this artifact is _not_ the main one.
The producer can expose its instrumented classes by creating a configuration that will "carry" this artifact:

.Declaring an outgoing variant
====

            // then it means we're using the legacy matching, without attributes, and that the metadata
            // we construct should _not_ include the constraints. We keep the constraints in the descriptors
            // because if we actually use attribute matching, we can select the platform variant which
            // does use constraints.

Fess is based on [OpenSearch](https://github.com/opensearch-project/OpenSearch)/[Elasticsearch](https://github.com/elastic/elasticsearch), but knowledge/experience about OpenSearch/Elasticsearch is _not_ required. Fess provides an easy to use Administration GUI to configure the system via your browser.

[NOTE]
====
For example, if a platform declares a constraint on `org:foo:1.1`, and that nothing else brings in a dependency on `foo`, `foo` will _not_ appear in the graph.
However, if `foo` appears, then usual conflict resolution would kick in.
If a dependency brings in `org:foo:1.0`, then we would select `org:foo:1.1` to satisfy the platform constraint.

Users can wrap common logic in a convention plugin.
For example, a code coverage plugin used as a convention plugin can survey code coverage for the _entire project_ and _not_ just a specific subproject.

TIP: Gradle highly recommends the use of Convention plugins.

The key factor is that a dependency should be a "callable".

A "**callable**" in Python is anything that Python can "call" like a function.

So, if you have an object `something` (that might _not_ be a function) and you can "call" it (execute it) like:

```Python
something()
```

or

```Python
something(some_argument, some_keyword_argument="foo")
```

then it is a "callable".

- the `pom.xml` or `ivy.xml` file will contain a _marker comment_ which tells Gradle that Gradle Module Metadata exists for this module

The goal of the marker is _not_ for other tools to parse module metadata: it's for Gradle users only.
It explains to Gradle that a _better_ module metadata file exists and that it should use it instead.
