Error when trying to apply 'java-test-fixtures' plugin using gradle

Question

I have a java project that uses fixtures where both unit and integration test use fixtures. Right now fixture classes are duplicated in every single module and we would like to have a single one where both IT and UT can access there.

Gradle recommends java-test-fixtures plugin but when we apply it we see the following error and doesn't work:

Warning:root project 'backend': Unable to resolve additional project configuration. Details: java.lang.IllegalStateException: Resolving dependency configuration 'testFixturesCompileOnly' is not allowed as it is defined as 'canBeResolved=false'. Instead, a resolvable ('canBeResolved=true') dependency configuration that extends 'testFixturesCompileOnly' should be resolved.

Here is the build.gradle file

plugins {
    id 'org.springframework.boot' version '2.4.1'
    id 'io.spring.dependency-management' version '1.0.10.RELEASE'
    id 'java'

// Integration test module
sourceSets {
    integrationTest {
        compileClasspath += sourceSets.main.output
        runtimeClasspath += sourceSets.main.output
    }
}

    integrationTestImplementation.extendsFrom testImplementation
    integrationTestRuntimeOnly.extendsFrom testRuntimeOnly
}

task integrationTest(type: Test) {
    useJUnitPlatform()
    description = 'Runs integration tests.'
    group = 'verification'

    testClassesDirs = sourceSets.integrationTest.output.classesDirs
    classpath = sourceSets.integrationTest.runtimeClasspath
}

idea {
    module {
        testSourceDirs += project.sourceSets.integrationTest.java.srcDirs
    }
}

// End 2 end test module
sourceSets {
    end2end {
        compileClasspath += sourceSets.main.output
        runtimeClasspath += sourceSets.main.output
    }
}

configurations {
    end2endImplementation.extendsFrom testImplementation
    end2endRuntimeOnly.extendsFrom testRuntimeOnly
}

task end2end(type: Test) {
    useJUnitPlatform()
    description = 'Runs integration tests.'
    group = 'verification'

    testClassesDirs = sourceSets.end2end.output.classesDirs
    classpath = sourceSets.end2end.runtimeClasspath
}

idea {
    module {
        testSourceDirs += project.sourceSets.end2end.java.srcDirs
    }
}

Any clue on how to fix it?
