Question

我为Selenium自动化创建了一个Maven项目。能够通过“RunAs Configurations”从Eclipse执行测试，如下面的截图：

我能够毫无错误地执行mvn clean和mvn package。但是当我执行命令java -cp target\auto-0.0.1-SNAPSHOT.jar scripts.FirstMain时，我收到如下错误：

D:\SeleniumProject>java -cp target\auto-0.0.1-SNAPSHOT.jar

</project>

我的代码是：

package scripts;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class FirstMain {
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  WebDriver wd = new FirefoxDriver();
  wd.get("http://www.gmail.com");
  wd.manage().window().maximize();
  try {
   Thread.sleep(5000);
  } catch (InterruptedException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  wd.close();
  wd.quit();
 }
}

Answer 1

您应该在类路径中添加您的lib目录。这样做：

java -cp "target\auto-0.0.1-SNAPSHOT.jar;target\lib\*" scripts.FirstMain

Answer 2

异常是因为在运行时没有找到您的依赖项，一个解决方案是将该依赖项添加到您的类路径，或者您可以使用maven程序集插件将jar包装为所有依赖项。link here
