Question

我通常在eclipse中构建/生成java类文件。但是，现在我需要让项目在没有eclipse的机器上工作，所以我使用maven直接从命令行构建它。然后我得到了以下错误，我在这里错过了什么吗？谢谢！

这是pom.xml

此外，这是＆＃34; mvn compile＆＃34;的输出，它成功了，只是没有创建目标/类文件夹及其类。

Answer 1

首先，您需要将pom.xml中的location /upload { auth_request /auth; ... } location = /auth { internal; proxy_pass http://auth_service.localhost; proxy_pass_request_body off; proxy_set_header Content-Length ""; proxy_set_header X-Original-URI $request_uri; }值更改为＆＃34; pom＆＃34;以外的值。让Maven运行编译插件。试试＆＃34; jar＆＃34;。

然后，如果您只想编译源代码，请使用

<packaging>

如果您想要打包的JAR，请致电

mvn compile

有关详细信息，请参阅Maven Build Lifecycle和Maven POM Reference。

Answer 2

你应该去：mvn编译（甚至mvn安装或类似的东西来测试它并制作一切）。
