如何在不蚀的情况下运行硒代码？

这是我的Java代码：

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

class mytestclass {
    public static void main(String[] args) {

    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    WebElement element = driver.findElement(By.name("q"));
    element.sendKeys("selenium!\n"); // send also a "\n"
    element.submit();

    // wait until the google page shows the result
    WebElement myDynamicElement = (new WebDriverWait(driver, 10))
              .until(ExpectedConditions.presenceOfElementLocated(By.id("resultStats")));

    List<WebElement> findElements = driver.findElements(By.xpath("//*[@id='rso']//h3/a"));

    // this are all the links you like to visit
    for (WebElement webElement : findElements)
    {
        System.out.println(webElement.getAttribute("href"));
    }
  }
}

我在cmd中输入了以下命令来编译.java文件：

javac -classpath "selenium-server-standalone-2.53.1.jar;selenium-java-2.53.1\selenium-2.53.1\selenium-java-2.53.1.jar;selenium-java-2.53.1\selenium-2.53.1\selenium-java-2.53.1-srcs.jar;D:\Adit\Selenium\selenium-java-2.53.1\selenium-2.53.1\libs\*.jar" mytestclass.java

当我尝试使用'java mytestclass'运行它时，在cmd中给我以下错误：

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/openqa/selenium/WebDriver

我试图使用gradle来编译jar文件。我的文件树如下所示：

在图像中突出显示的libs文件夹中，我已复制了所有jar文件。我提供以下图片：

我的build.gradle文件包含以下几行：

apply plugin: 'java'

dependencies {
compile fileTree(dir: 'libs', include: '*.jar')
}

现在，如果我给命令“ gradle build”，那么它会显示“ BUILD SUCCESSFUL”。

:compileJava
:processResources UP-TO-DATE
:classes
:jar
:assemble
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:test UP-TO-DATE
:check UP-TO-DATE
:build

BUILD SUCCESSFUL

Total time: 2.738 secs

但是，如果我尝试使用命令“ java mytestclass”运行编译的类文件，则会再次遇到相同的错误。

我该如何解决？我要运行硒而不发生蚀。我正在运行Windows，而我的Java版本是1.8.0_101。
