Question

我正在尝试使用spring boot和maven设置一个简单的java rest服务，我已经下载了maven，并且我的pom.xml位于与src相同的文件夹中，所以它是 src＆amp; pom.xml - ＆gt;主要 - ＆gt; java - ＆gt;你好

当我在hello文件夹中并尝试运行maven clean package来构建我的jar文件时，它说找不到命令maven。

我仍然是java web dev的新手，所以确保一切都配置正确对我来说很难。我已经下载了maven但是我需要在我的项目中拥有实际的maven文件吗？

真的很感激任何帮助。

Answer 1

pom.xml必须位于＆＃34; root＆＃34;文件夹中。

/yourApp:
   - pom.xml
   - /src
        - /main/java
           ...
        - /test/java 
           ...

Answer 2

虽然你正在犯@Ralph在他的回答中给出的错误，但我不认为这个错误会给出你得到的错误信息。对我而言，听起来你还没有正确安装maven。 The install steps are at the bottom of this page。确保您已正确遵循指示。

您添加的错误表示您运行命令的目录中没有pom。您需要在“pom.xml”文件所在的同一目录中运行该命令。

无法在弹出启动的项目中找到命令maven
