“导入 org.springframework 无法解决。

这是我的POM.xml文件：

下面是我的java类：

import org.springframework.batch.core.Job;
import org.springframework.batch.core.JobExecution;
import org.springframework.batch.core.JobParameters;
import org.springframework.batch.core.launch.JobLauncher;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {
    public static void main(String[] args) {
        String[] springConfig  =
            {
                "spring/batch/jobs/job-hello-world.xml"
            };
        ApplicationContext context =
            new ClassPathXmlApplicationContext(springConfig);
        JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
        Job job = (Job) context.getBean("helloWorldJob");
        try {
            JobExecution execution = jobLauncher.run(job, new JobParameters());
            System.out.println("Exit Status : " + execution.getStatus());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

我在 App 中的 import 语句中收到错误.java classnd 这是消息：

“导入 org.springframework 无法解决。

我清楚地提到了POM中的依赖关系.xml，但我的java类仍然无法从那里选择依赖关系。
