Hier ist meine Klasse. Ich verwende Selenium Chrome WebDriver, um Aktionen auf einer Website zu automatisieren. Mein Problem ist, dass ich einen NoClassDefFoundError bekomme, aber das kann nicht möglich sein, da ich alle erforderlichen .jars-Dateien in meinem Build-Pfad aufgenommen habe. Was ist los?NoClassDefFoundError mit Selenium Chrome WebDriver
public class TwitterAutoBot {
private WebDriver driver;
private String baseUrl;
private StringBuffer verificationErrors = new StringBuffer();
@Before
public void setUp() throws Exception {
// Google Chrome
File file = new File("C:\\Users\\User\\plugins\\TwitterAutoBot\\src\\chromedriver.exe");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
driver = new ChromeDriver();
// Firefox
// driver = new FirefoxDriver();
baseUrl = "https://www.twitter.com";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
@Test
public void testValidation() throws Exception {
// Authentication information
String username = "asdfasdfasdf";
String password = "asdf123!";
// Open site
launchActivity("/");
// Maximize window
maximizeWindow();
// Enter authentication information
sendKeysAndWait("signin-email", username);
sendKeysAndWait("signin-password", password);
// Log in
clickButtonAndWait("//button[@type='submit']");
// Send 40 messages per hour for a total of 960 per day
for (int i = 1; i < 960; i++) {
sendMessageAndWait();
}
System.out.println("All messages have been sent.");
}
public void sendMessageAndWait() throws Exception {
driver.findElement(By.id("tweet-box-home-timeline")).click();
driver.findElement(By.xpath("(//button[@type='button'])[17]")).click();
driver.findElement(By.id("global-new-tweet-button")).click();
driver.findElement(By.xpath("(//button[@type='button'])[644]")).click();
System.out.println("Message sent.");
sleep();
}
private void maximizeWindow() throws InterruptedException {
driver.manage().window().maximize();
sleep();
}
/**

* @param extension The remainder of the URL, after baseUrl
*/
private void launchActivity(String extension) {
driver.get(baseUrl + extension);
}
/**s

* @param elem The element to send the keys
* @param keys The string to write to the element

*/
private void sendKeysAndWait(String elem, String keys) throws InterruptedException {
Math.random();
driver.findElement(By.id(elem)).clear();
driver.findElement(By.id(elem)).sendKeys(keys);
sleep();
}
/**

private void clickButtonAndWait(String id) throws InterruptedException {
driver.findElement(By.id(id)).click();
sleep();
}
private void sleep() throws InterruptedException {
int randomWaitDuration = 75000 + (int)(Math.random() * 105000); ;
Thread.sleep(randomWaitDuration);
System.out.println(randomWaitDuration + " minutes since your last tweet.");
}
@After
public void tearDown() throws Exception {
driver.quit();
String verificationErrorString = verificationErrors.toString();
if (!"".equals(verificationErrorString)) {
fail(verificationErrorString);
}
}
}
bekomme ich folgende NoClassDefFoundError:
