 ### Customization
 
 You can also explicitly specify the configuration
-```groovy
-tasks.named('detectCollisions', DetectCollisionsTask).configure {
-	configurations.from(project.configurations.runtimeClasspath)
+```
+tasks.named<DetectCollisionsTask>("detectCollisions").configure {
+    configurations.from(project.configurations.runtimeClasspath)

 ```
 
 To ignore certain conflicts you can add exclude patterns that match collisions you are not interested in e.g.
 
-```groovy
-tasks.named('detectCollisions', DetectCollisionsTask).configure {
-	collisionFilter {
-		exclude('**.html', '**.txt', '**.properties')
-	}
+```kotlin
+tasks.named<DetectCollisionsTask>("detectCollisions").configure {
+    collisionFilter {
+        exclude("**.html", "**.txt", "**.properties")
+    }
 }
