所以我有一个完美的石英工作，定义如下：

package willkara.monkai.jobber;

import java.util.Date;
import org.joda.time.DateTime;
import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import willkara.monkai.impl.MonKaiClientImpl;


/* this is a test Quartz job to show that we can inject jobs into the jobscheduler from an external location */
public class tester implements Job {

    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        System.out.println("I REALLY HOPE THIS WORKS");
        DateTime dt = new DateTime();

        System.out.println(dt.getDayOfYear());

    }
}

每当我在站点上的石英调度程序中运行作业时，一切都运行良好，直到它尝试运行 JodaTime 命令。

它输出 I REALLY HOPE THIS WORKS 文本，但之后我得到了这个堆栈跟踪：

I REALLY HOPE THIS WORKS

我正在尝试从我自己编写的不同外部库运行代码。整个项目使用 maven 进行管理。我只是使用 JodaTime 作为测试来确保/查看它是否会运行来自外部库的代码。

问题是您已经在类路径中使用 JodaTime 库编译了源代码，但它们在目标类路径中不可用。确保它们位于您的应用服务器的 lib 目录中或将它们包含在您的工件中。

您必须在项目目录中有一个“libs/”文件夹，其中包含 jar；是这样吗？
