Appium脚本为android应用程序在线程 "main "中抛出 "异常 "java.lang.NoClassDefFoundError：orgobjectwebasmType。

Question

请找到我下面的代码，帮我摆脱异常。

我使用Appium 1.17.1版本，cglib3.3.0 jar，java-client-7.3.0 jar，Selenium-java-3.141.59，项目为java项目。

请找到以下代码

HybridBase.java

  public class HybridBase {

        public static AndroidDriver<AndroidElement> capabilities(String device) throws MalformedURLException
        {
            AndroidDriver<AndroidElement> driver;
            File f = new File("src");
            File fs = new File(f,"ApiDemos-debug.apk");
            DesiredCapabilities cap=new DesiredCapabilities();

            if(device.equals("real")){
                cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android"); 
            }
            else if(device.equals("emulator")){
                cap.setCapability(MobileCapabilityType.DEVICE_NAME, "Android");
            }
            cap.setCapability(MobileCapabilityType.UDID, "3200f0fdb4e8753b");

        //  cap.setCapability(MobileCapabilityType.UDID, "3200f0fdb4e8753b");
            cap.setCapability(MobileCapabilityType.FULL_RESET, false);
        cap.setCapability(MobileCapabilityType.NO_RESET, true);

            cap.setCapability(MobileCapabilityType.APP, fs.getAbsolutePath());
            driver=new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"),cap);
            return driver;


        }

    }

Basic.java

public class Basic extends HybridBase {

    public static void main(String[] args) throws MalformedURLException {
        // TODO Auto-generated method stub

        AndroidDriver<AndroidElement> driver = capabilities("real");

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);


        HomePage h = new HomePage(driver);

        // driver.findElementByXPath("//android.widget.TextView[@content-desc='Preference']").click();
        //driver.findElementByXPath("//android.widget.TextView[@text='Preference']").click();

        h.preferences.click();

        Preferences p =new Preferences(driver);

        //driver.findElementByXPath("//android.widget.TextView[@text='3. Preference dependencies']").click();

        p.dependencies.click();
        driver.findElementById("android:id/checkbox").click();
        driver.findElementByXPath("(//android.widget.RelativeLayout)[2]").click();
        driver.findElementByClassName("android.widget.EditText").sendKeys("Karthi");
        driver.findElementsByClassName("android.widget.Button").get(1).click();
    }

}

首页.java

public class HomePage {

    public HomePage(AppiumDriver driver) {
        PageFactory.initElements(new AppiumFieldDecorator(driver), this);
        // PageFactory.initElements(driver, this);
    }

    @AndroidFindBy(xpath = "//android.widget.TextView[@text='Preference']")
    public WebElement preferences;

}

Preferences.java

public class Preferences {

    public Preferences(AppiumDriver driver) {
        PageFactory.initElements(new AppiumFieldDecorator(driver), this);
        // PageFactory.initElements(driver, this);
    }

    @AndroidFindBy(xpath = "//android.widget.TextView[@text='3. Preference dependencies']")
    public WebElement dependencies;

}

结果：应用程序被打开但没有执行任何操作，并抛出以下异常。应用程序被打开，但没有执行任何操作，并抛出以下异常。

请帮我摆脱上述异常情况。

Answer 1

这可能是由于无法使用 罐子. 它可以从以下链接下载。

http:/download.forge.ow2.orgasm。

Answer 2

我通过添加asm-6.1 jar和添加cglib-3.2.6 jar而不是cglib-3.3.0 jar得到了上述问题的解决方法

cglib jar的链接 - https:/github.comcglibcglibreleases。asm-6.1 jar的链接--。http:/download.forge.ow2.orgasm。

如果有任何需要澄清的地方，请随时联系......。

Answer 3

This issue occurs due to the incompatible jar. try to use the latest jar from the below  link,

https://github.com/cglib/cglib/releases
