SpringBoot [3.0.0] LocalServerPort is not autowired

I have a pull request to bump Spring Boot from 2.7.6 to 3.0.0. It fails with a compilation error on: import org.springframework.boot.web.server.LocalServerPort

If I try to resolve it by an import suggested by IDE (import org.springframework.boot.test.web.server.LocalServerPort), the port field is still null when tests are run.

Here's the test that fails:

package com.github.artamonovkirill

import com.tomtom.http.HttpClient
import org.springframework.boot.test.context.SpringBootTest
import org.springframework.boot.test.web.server.LocalServerPort
import spock.lang.Specification

import static com.tomtom.http.response.ResponseCode.OK
import static org.springframework.boot.test.context.SpringBootTest.WebEnvironment.RANDOM_PORT

@SpringBootTest(webEnvironment = RANDOM_PORT, classes = [ExtremeStartup, NoWebClient])
class QueryControllerSpec extends Specification {

    @LocalServerPort
    def port
    def http = new HttpClient()

    def 'exposes query endpoint'() {
        when:
        def response = http.get(url: "http://localhost:${port}?q=bar")

        then:
        response.statusCode == OK
        response.body == 'bar'
    }

}

(https://github.com/artamonovkirill/extreme-startup/blob/main/groovy/springboot/src/test/groovy/com/github/artamonovkirill/QueryControllerSpec.groovy)

I also didn't any mentions of @LocalServerPort in v3 release notes.

I figured out it's an issue with Spock Spring module: https://github.com/spockframework/spock/issues/1539
