{project_name} has packed some functionality in features, including some disabled features, such as Technology Preview and deprecated features. Other features are enabled by default, but you can disable them if they do not apply to your use of {project_name}.

== Enabling features

Some supported features, and all preview features, are disabled by default. To enable a feature, enter this command:

[source,bash]
----
bin/kc.[sh|bat] build --features="<name>[,<name>]"
----

For example, to enable `docker` and `token-exchange`, enter this command:

[source,bash]
----
bin/kc.[sh|bat] build --features="docker,token-exchange"
----

To enable all preview features, enter this command:

[source,bash]
----
bin/kc.[sh|bat] build --features="preview"
----

Enabled feature may be versioned, or unversioned.  If you use a versioned feature name, e.g. feature:v1, that exact feature version will be enabled as long as it still exists in the runtime.  If you instead use an unversioned name, e.g. just feature, the selection of the particular supported feature version may change from release to release according to the following precedence:

1. The highest default supported version
1. The highest non-default supported version
1. The highest deprecated version
1. The highest preview version
1. The highest experimental version

== Disabling features

To disable a feature that is enabled by default, enter this command:

[source,bash]
----
bin/kc.[sh|bat] build --features-disabled="<name>[,<name>]"
----

For example to disable `impersonation`, enter this command:

[source,bash]
----
bin/kc.[sh|bat] build --features-disabled="impersonation"
----

It is not allowed to have a feature in both the `features-disabled` list and the `features` list.

When a feature is disabled all versions of that feature are disabled.
