+/**
+ * Workarounds because `SamWithReceiver` not working in test sources
+ * https://youtrack.jetbrains.com/issue/KTIJ-14684
+ *
+ * The `SamWithReceiver` plugin is automatically applied by the `kotlin-dsl` plugin.
+ * It converts all [org.gradle.api.Action] so the parameter is the receiver:
+ *
+ * ```
+ * // with SamWithReceiver ✅
+ * tasks.configureEach {
+ *   val task: Task = this
+ * }
+ *
+ * // without SamWithReceiver
+ * tasks.configureEach { it ->
+ *   val task: Task = it
+ * }
+ * ```
+ *
+ * This is nice because it means that the Dokka Gradle Plugin more closely matches `build.gradle.kts` files.
+ *
+ * However, [IntelliJ is bugged](https://youtrack.jetbrains.com/issue/KTIJ-14684) and doesn't
+ * acknowledge that `SamWithReceiver` has been applied in test sources. The code works and compiles,
+ * but IntelliJ shows red errors.
+ *
+ * These functions are workarounds, and should be removed ASAP.
