By default, the runner will attempt to find a Gradle distribution based on where the `GradleRunner` class was loaded from. That is, it is expected that the class was loaded from a Gradle distribution, as is the case when using the `gradleTestKit()` dependency declaration.

They can be set from the command line using the `-P` / `--project-prop` <<command_line_interface.adoc#sec:environment_options, environment option>>.

The following examples demonstrate how to set project properties in different ways.

*Example 1:* Setting a project property via the *command line*:
====
----
$ gradle -PgradlePropertiesProp=commandLineValue
