Hello, I am using spring boot 3.2 (web not webflux)+ wiremock 3.3.1. when I start my integration which is annotated with , @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment._RANDOM_PORT_) @AutoConfigureWebClient(registerRestTemplate = true) @AutoConfigureMockMvc and in the class I am creating wireMockServer using below code, @RegisterExtension static WireMockExtension wireMockServer = WireMockExtension._newInstance_() .options( _wireMockConfig_() .dynamicPort() .usingFilesUnderClasspath(“wiremock”) ) .build(); But getting below error when I run the integration-test,

java.lang.IncompatibleClassChangeError: class org.eclipse.jetty.http2.server.HttpChannelOverHTTP2 has interface org.eclipse.jetty.server.HttpChannel as super class

Do we need any other additional dependencies required inorder to run with spring-boot 3.2?

Try switching to the standalone WireMock JAR in your dependencies.

Thank you @Tom for the prompt reply. But the standalone dependency in maven is haing type pom for the latest versions, <!-- https://mvnrepository.com/artifact/com.github.tomakehurst/wiremock-jre8-standalone --> <dependency>

<groupId>com.github.tomakehurst</groupId>

<artifactId>wiremock-jre8-standalone</artifactId>

<version>3.0.1</version>

<type>pom</type>

<scope>test</scope>

That’s not the latest one

May be I can use “2.35.1”

You need

wiremock-standalone

as the artifactId and

3.3.1

as the version

ah ok.Thanks. Let me give it a try.

I have the same issue and changing the dependency didn't solve :/
