+Similarly to [_Configure Gradle to Allow Listing All Subproject Dependencies_]({{< ref 2020-07-27-gradle-list-all-dependencies >}}), it can be useful to find out the dependencies that are in use by your Gradle plugins.
+
+Fortunately, there is the [`buildEnvironment` Gradle task](https://solidsoft.wordpress.com/2016/06/07/gradle-tricks-display-buildscript-dependencies/) that allows us to list the project's buildscript dependencies (output trimmed for brevity):
+
+```
