Spring Boot应用程序在启动后立即停止

Question

我在我的工作区中使用STS IDE运行了几个Spring Boot应用程序，在我对其中一个项目进行maven更新后，每个项目都在应用程序启动过程后立即停止。我甚至创建了一个最小的例子，只是为了开始一些事情，同样的事情发生了。

@SpringBootApplication
public class App implements CommandLineRunner {

 public static void main(String[] args) {
    SpringApplication.run(App.class, args);
 }

 @Override
 public void run(String... arg0) throws Exception {
        System.out.println("Started...");

 }
}

这是我的pom.xml

即使是那些入门示例也会在启动后立即停止。我会非常感谢这里的一些帮助。

编辑：正如Alexandru Marina在评论中所说，我使用的是快照而不是稳定的发布。

我也有类似的问题。我在本地Maven缓存中发现了一个损坏的tomcat-embed-core-8.5.4依赖项。请删除它并运行Maven构建再次检索依赖项。
