java - Maven 命令 "mvn clean jetty:run"和其他 mvn 命令在 Eclipse 中不起作用

Question

我正在关注 Google Cloud 文档 https://cloud.google.com/appengine/docs/flexible/java/using-cloud-sql用于开发应用程序。根据文档的建议，应使用 mvn clean jetty:run 命令在本地测试应用程序。除此之外，我也尝试过其他命令，例如 mvncompile 。以下是我在本地测试应用程序时遵循的步骤:-

右键单击我的项目 -> 运行方式 -> Maven 构建，然后启动配置框，我在其中输入 mvn clean jetty:在“目标”文本框中运行，然后单击“运行”

以下是我的 pom.xml 文件:-

请提出建议，我应该做哪些改变。

Answer 1

仅输入clean jetty:run，删除mvn。
