Question

我使用start.spring.io网址创建了一个小型春季网络应用。我下载了项目，我试图在pom.xml所在的文件夹下运行mvn package命令。我收到了以下错误。

我的c：\ LENOVO-PC \ Users \ lenovo.m2文件夹中没有settings.xml。但是我在F：\ java \ apache-maven-3.5.0 \ conf文件夹中有全局settings.xml，但是其中的所有条目都被注释掉了。任何人都可以帮助我。

我的pom.xml内容是

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

如果使用标准布局，请删除relativePath。错误清楚地表明相对路径指向没有pom.Hence它正在给出该错误。

Answer 2

有趣的是，这个问题与我的想法不同。我评论了pom.xml中的relativePath但是没有帮助。此外，我禁用了我的Avast Antivirus，然后解决了这个问题。感谢大家提供有关此问题的意见。祝周末愉快。
