maven—使用没有spring/cdi的普通java servlet创建一个新的vaadinflow16/17项目

vaadin流的起始页已更改。该页面现在提供了仅为springboot配置的新项目。这个页面的上一个版本提供了“纯Javaservlet”和spring/cdi选项。
vaadin文档建议手动使用maven原型。但是maven存储库 com.vaadin… 似乎是针对瓦丁8和更早,没有瓦丁10和更高版本。
关于学习maven的vaadin页面展示了一个使用 viritin-vaadin-flow-archetype 作为原型。但viritin是一个第三方项目,它将添加我目前不需要的库。
➥ 有没有办法启动一个新的vaadin16项目,只使用在jetty或tomcat上运行的普通java servlet,而不使用spring/cdi(或vaadin 17(预发布)
或者瓦丁有限公司决定现在只支持spring(那将是非常不幸的。)

至少是maven的原型 vaadin-archetype-application 似乎适用于v16之前的版本:

mvn archetype:generate -DarchetypeGroupId=com.vaadin -DarchetypeArtifactId=vaadin-archetype-application -DarchetypeVersion=LATEST

我应该更新那个教程。。。谢谢你的提示。

我成功地使用了maven原型 vaadin-archetype-application 如亚历杭德罗杜阿尔特的回答所示。

pom示例

我调整了这个原型生成的pom文件。主要是我更新到各种作品的最新版本,包括vaadin17测试版。
下面是我得到的pom,如下所示。其他人可能希望将初始pom与这个pom进行比较,以考虑各种问题。
