配置好maven后，找不到 POM.xml？

Question

系统是Windows 10 家庭版

我按照官网的指引（https://maven.apache.org/guid...），下载了压缩包，解压后配置了PATH目录

输入

mvn -v

后，显示如下

Apache Maven 3.5.3 (3383c37e1f9e9b3bc3df5050c29c8aff9f295297; 2018-02-25T03:49:05+08:00)
Maven home: D:\apache-maven-3.5.3\bin\..
Java version: 10, vendor: Oracle Corporation
Java home: D:\java\jdk
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

然后我尝试进行第二步

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

按照官网的说法，应该会生成一个目录，但是我这边却提示说

[INFO] Scanning for projects...

我打开 Help 1 的链接后也没有说怎么配置默认的POM文件，网上也没有找到解决方法

谢谢大家！

Answer 1

原因是下面的pom.xml已经存在,删除这个pom.xml,重新测试即可

D:\_project\test\pom.xml
