ここは私のクラスです。私はSelenium Chrome WebDriverを使ってウェブサイト上のアクションを自動化しています。私の問題は、NoClassDefFoundErrorを取得することですが、ビルドパスに必要なすべての.jarsファイルが含まれているため、これを行うことはできません。何が起こっている？NoClassDefFoundError with 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
* Writes a string to an HTML element and waits a random time
* @param elem The element to send the keys
* @param keys The string to write to the element
* @throws InterruptedException
*/
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();
}
/**
*
* @param id The id of the button found in HTML
* @throws InterruptedException
*/
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);
}
}
}
