一旦我导入 maven 项目并从 ：以 Maven 构建>运行，我就会收到以下错误：
我删除了我的.m2文件夹，与Eclipse相关的所有内容都无法从头开始，但仍然不起作用。
我试过：Maven>更新项目>强制更新，但不起作用。
构建错误：

有什么帮助吗？
此依赖项中有一个拼写错误：
<dependency>
<groupId>org.springframeswork</groupId>
<artifactId>spring-core</artifactId>
<version>${org.springframework-version}</version>
</dependency>
请注意"弹簧框架"末尾不需要的"s"。
将org.springframeswork替换为org.springframework
