How to fix NoSuchMethodError on startKoin() method

I'm trying to launch tests with Koin DI help like in the example https://insert-koin.io/docs/2.0/documentation/koin-core/index.html#_making_your_test_a_koincomponent_with_kointest or https://insert-koin.io/docs/2.0/getting-started/junit-test/ but every time getting NoSuchMethodError. What I am doing wrong?

First I was using already created modules from main package, but there was this error. Then I created modules in test package, but error is still the same.

My code

class ComponentA
class ComponentB(val a: ComponentA)

class SignInTest : KoinTest {

    val componentB : ComponentB by inject()

    @Before
    fun before() {
        startKoin { modules(
            module {
                single { ComponentA() }
                single { ComponentB(get()) }
            }) }
    }

    @Test
    fun test_test() {
        val componentA = get<ComponentA>()

        assertNotNull(componentA)
        assertEquals(componentA, componentB.a)
    }

    @After
    fun after() {
        stopKoin()
    }

java.lang.NoSuchMethodError: org.koin.core.definition.BeanDefinition.(Lorg/koin/core/qualifier/Qualifier;Lorg/koin/core/qualifier/Qualifier;Lkotlin/reflect/KClass;)V
