Question

这是我的pom.xml文件，当我导入项目时，它在pom.xml文件的顶行显示错误为“无法传输xstream，因为它缓存在本地目录中，分辨率不会重新尝试，直到中心的更新间隔已经过去或强制更新“

我是全新的，请帮助我。

我正在通过JPA和Hibernate的Spring教程学习，但我坚持这个请帮助我，并提前感谢

Answer 1

在构建项目时使用-U参数。

mvn clean install -U

如果不起作用，请从当地的maven repo中删除xstream的文件夹并执行

 mvn clean install -U

无法在spring工具中下载maven依赖项
