@SpringBootTest with spock and spring boot 3.0.0 doesn't load application context correctly

[mariopagano]

Using spring boot 3.0.0 and the following spock dependencies:

              <dependency>
			<groupId>org.apache.groovy</groupId>
			<artifactId>groovy</artifactId>
			<version>4.0.6</version>
			<type>pom</type>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.spockframework</groupId>
			<artifactId>spock-core</artifactId>
			<version>2.3-groovy-4.0</version>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.spockframework</groupId>
			<artifactId>spock-spring</artifactId>
			<version>2.3-groovy-4.0</version>
			<scope>test</scope>
		</dependency>

sampleTestIT.groovy test class:

package com.example.spocktest

import org.spockframework.util.Assert
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.boot.test.web.client.TestRestTemplate
import spock.lang.Specification

@SpringBootTest(classes = [SpockTestApplication])
class sampleTestIT extends Specification {
    @Autowired
    TestRestTemplate testRestTemplate

    @Autowired
    SampleService sampleService;

    def 'app context'() {
        expect:
        Assert.notNull(testRestTemplate)
    }

    def 'app context2'() {
        expect:
        Assert.notNull(sampleService)
    }
}

Output:

I'm afraid this is out of Spring Boot's control. Spock's Spring Extension tries to use org.springframework.test.util.MetaAnnotationUtils which was deprecated in Spring Framework 5.3 and has been removed in 6.0. This prevents it from finding the @BootstrapWith annotation with which @SpringBootTest is meta-annotated. You can work around the problem by using @ContextConfiguration directly on your test class. Spock's Spring Extension is able to find this annotation.

This has already been reported to the Spock Team: spockframework/spock#1539.

dependencies are not compatible

FWIW, this issue was fixed in spockframework/spock#1541. A formal release has not been made yet that includes it, but you can still get the fix using their 2.4-M1 milestone release. Or you can work around it by simply adding the @ContextConfiguration annotation to your test/spec that @wilkinsona mentioned above. .
