java - 从 IDE 运行时 Geckodriver 工作正常，但从可执行 jar 运行时抛出异常

Question

我使用selenium通过firefox下载文件。当我从 IDE (eclipse) 运行时一切正常，但是当我提取可执行 jar 时，出现以下异常:

    Exception in thread "main" org.openqa.selenium.WebDriverException: Build info: version: 'unknown', revision: 'f148142cf8', time: '2019-07-01T21:24:57'

        at org.openqa.selenium.firefox.FirefoxDriver.toExecutor(FirefoxDriver.java:179)
        at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:154)

private void initSelenium() {
        System.setProperty("webdriver.gecko.driver",         Config.getInstance().getFIREFOX_DRIVER_PATH());
    }

private WebDriver createFirefoxDriverWithDownloadFolder(String downloadFolder) {
        FirefoxProfile profile = new FirefoxProfile();
        FirefoxOptions options = new FirefoxOptions();
        profile.setPreference("browser.download.folderList", 2);
        profile.setPreference("browser.download.dir", downloadFolder);
        profile.setPreference("browser.download.manager.showWhenStarting", false);
        profile.setPreference("browser.helperApps.neverAsk.openFile", "application/x-msdownload");
        profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/x-msdownload, application/zip");

        options.setProfile(profile);

        WebDriver driver = new FirefoxDriver(options);
        return driver;
    }

在属性文件中: FIREFOX_DRIVER_PATH = C:\geckodriver.exe

Answer 1

通过使用“将所需的库打包到生成的 jar 中”而不是“将所需的库提取到生成的 jar 中”提取可运行的 jar 来解决
