ava：软件包org.springframework.boot不存在

Question

为什么要在intellij中运行一个简单的springboot项目这么大的事呢？

同一个问题也已经在前面讨论过，但是这些解决方案对我不起作用。因此，我提出了一个新问题。

IntelliJ IDEA 2020.1.2（社区版） Build＃IC-201.7846.76，建于2020年6月1日

我已经使用spring initializr创建了一个简单的基于Maven的springboot项目

我的系统上安装了JDK 11。同一项目在Eclipse中可以正常工作。与intellij的关系是什么？为什么有时使它适用于简单的事情如此困难。

我的pom.xml

    teams = pd.DataFrame(requests.get('https://api.opendota.com/api/teams').json())

    # ...get Team ID of :arg:`team`
