This example application demonstrates that there's an issue with executing Cucumber features inside applications based on Spring Boot 3.2.0.
Creating an uberjar and running it via ./gradlew bootJar && java -jar build/libs/cucumber-spring-boot-3.2.0-0.0.1-SNAPSHOT.jar
leads to the following error:
org.junit.platform.commons.JUnitException: TestEngine with ID 'cucumber' failed to discover tests

Running the app from (for example) IntelliJ IDEA works fine.
The feature in src/main/resources/features/example.feature is executed without any errors in that case.
Using versions of Spring Boot before 3.2.0, the application runs without issues both from within IntelliJ and as an uberjar.
Replace the Spring Boot pluging version 3.2.0 with 3.1.6 in build.gradle, for example, to build an uberjar that functions as intended.
The problem is caused by recent changes to the code that supports Spring Boot's uberjar loading: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.2-Release-Notes.
