SpringApplication.run(HelloWorldExampleApplication.class，args)；

Question

错误在以下代码行中-

SpringApplication.run(HelloWorldExampleApplication.class, args);

上面写着-

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"，它显示mvn不能被识别为int/ext命令。

我正在使用eclipse IDE中的springboot sts插件。请给我。帮帮忙，因为我是个初学者。
