HtmlUnit Android: NoSuchFieldError: Нет статического поля INSTANCE типа Lorg / apache / http / conn / ssl / AllowAllHostnameVerifier

Я пытаюсь запустить HtmlUnit на Android. Я думаю, этот ответ раньше работал со старыми библиотеками, но не сейчас. Другие темы, связанные с этим вопросом, не касаются Kotlin на Android или устарели.

Рассмотрим код ниже:

https://github.com/JimClermonts/HtmlUnit-for-Android

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    doAsync {
        val webClient = WebClient()
        var page: HtmlPage = webClient.getPage<HtmlPage>("http://www.google.com")
        val searchBox = page.getElementByName<HtmlInput>("q")
        searchBox.valueAttribute = "htmlunit"

        val googleSearchSubmitButton: HtmlSubmitInput = page.getElementByName("btnG") // sometimes it's "btnK"
        page = googleSearchSubmitButton.click()

        val resultStatsDiv: HtmlDivision = page.getFirstByXPath("//div[@id='resultStats']")

        System.out.println(resultStatsDiv.asText()) // About 309,000 results

        webClient.close()
    }
}

Вот мои зависимости проекта:

Я не знаю, почему вы указываете транзитивные зависимости, вам это не нужно, если вы не хотите каким-либо образом настраивать его.

Я закомментировал их, и приложение скомпилировано и развернуто на устройстве.
