QUESTION

java.lang.RuntimeException: not supported: class org.spockframework.gentyref.CaptureTypeImpl

Asked 2022-Mar-30 at 13:59

Spock is being used to execute an integration test in a Spring Boot project (2.1.18.RELEASE). When I run with 1.3-groovy-2.5, I get this error:

If I update Spock to a more recent version (eg. 2.1-groovy-2.5) I get this error:

I am using Java 11 and Maven 3.6.3. My pom.xml is rather long, so I've reduced it to some snippets that focus on versions and test dependencies:

                        </plugin>

Any help with troubleshooting this further is greatly appreciated. I modelled my pom.xml after the examples in the spock framework project:

Regarding java.util.ServiceConfigurationError: org.junit.platform.engine.TestEngine: org.spockframework.runtime.SpockEngine Unable to get public no-arg constructor

Spring Boot 2.1.18.RELEASE is really old, it manages JUnit 5 to 5.3.2 while Spock 2.x requires >= 5.8. You can try setting <junit-jupiter.version>5.8.1</junit-jupiter.version> if you can't upgrade Spring Boot to a more recent version.

As for the type reflection error, we can't say much since you didn't share any code. Only that com.foo.controller.ConversionsController.createConversionJob(ConversionsController.java:68) probably has some weird generics or is calling something that does.

Install byte-buddy

You can download it from GitHub.
You can use byte-buddy like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the byte-buddy component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .

Support

The work on Byte Buddy is also possible thanks to a row of supporters that have dedicated regular resources and attention to the project. Please take your time to have a look at those supporters and their offerings. <a href="https://www.scienta.no"> <img src="https://bytebuddy.net/logos/scienta.png" height="50" alt="Scienta AS"/> </a>      <a href="https://www.instana.com"> <img src="https://bytebuddy.net/logos/instana.png" height="50" alt="Instana"/> </a>      <a href="https://www.sqreen.com"> <img src="https://bytebuddy.net/logos/sqreen.png" height="50" alt="Sqreen"/> </a>      <a href="https://www.elastic.co"> <img src="https://bytebuddy.net/logos/elastic.png" height="50" alt="Elastic"/> </a>.
