 You need to enable the support of JUnit 5 in SBT:
 ```scala
 // plugins.sbt
-addSbtPlugin("com.github.sbt.junit" % "sbt-jupiter-interface" % "0.15.0")
+// version 0.15.1+ is important, earlier versions have a bug preventing properly running Cucumber tests (https://github.com/sbt/sbt-jupiter-interface/issues/142)
+addSbtPlugin("com.github.sbt.junit" % "sbt-jupiter-interface" % "0.15.1")
 // build.sbt
 libraryDependencies += "com.github.sbt.junit" % "jupiter-interface" % JupiterKeys.jupiterVersion.value % Test
 ```
 
-And, because of an [issue in the SBT integration](https://github.com/sbt/sbt-jupiter-interface/issues/142), you need to
-set the following property in the `junit-platform.properties` file (must be in the test resources classpath, usually
-`src/test/resources`):
-```properties
-cucumber.junit-platform.discovery.as-root-engine=false
-```

 ### JUnit 4
 
 Add the `cucumber-junit` dependency to your project.
