Question

错误在以下代码行中 -

SpringApplication.run(HelloWorldExampleApplication.class, args);

它说 -

Multiple markers at this line
    - The type org.springframework.context.ConfigurableApplicationContext cannot be resolved. It is indirectly referenced 
     from required .class files
    - The method run(Class<?>, String...) from the type SpringApplication refers to the missing type 
     ConfigurableApplicationContext

我试过运行命令"mvn dependency:purge-local-repository"，并说mvn没有被识别为int / ext命令。

我在eclipse IDE中使用springboot sts插件。请。帮助，因为我是一个初学者。
