Can Eclipse import a Maven Web project as a "Dynamic Web Application"?
提问by jsidlosky
High Level Goal:Create a single Maven Web Application project that can be used correctly in both Netbeans and Eclipse
高级目标：创建一个可以在 Netbeans 和 Eclipse 中正确使用的 Maven Web 应用程序项目
When converting a Maven project to Eclipse, the project type doesn't seem to be set to Dynamic Web App when using the command: mvn eclipse:eclipse -Dwtpversion=2.0
将Maven项目转换为Eclipse时，使用命令时项目类型似乎没有设置为Dynamic Web App：mvn eclipse:eclipse -Dwtpversion=2.0
In Eclipse, if creating a Dynamic Web Application, many more options are shown in the Project Explorer, such as: JAX-WS Web Services, Deployment Descriptor, etc.It's a completely different framework structure.
在 Eclipse 中，如果创建动态 Web 应用程序，项目资源管理器中会显示更多选项，例如： JAX-WS Web 服务、部署描述符等。这是一个完全不同的框架结构。
Also, after converting to Eclipse with the above command, I can't "Run" it even though the output from the conversion says: [INFO] Using as WTP server : Apache Tomcat v7.0. Instead of wanting to run as a web service, it asks me if this is Java Servlet, Applet, or Unit test.
此外，在使用上述命令转换为 Eclipse 后，即使转换的输出显示：[INFO] 用作 WTP 服务器：Apache Tomcat v7.0，我也无法“运行”它。它不想作为 Web 服务运行，而是询问我这是 Java Servlet、Applet 还是单元测试。
With a Dynamic Web App (native Eclipse), this is what shows up when Running the project:
使用动态 Web 应用程序（本机 Eclipse），这是运行项目时显示的内容：
Maybe I am asking too much of Eclipse, and to get the built-in web app functionality, it can't come from Maven?
也许我对 Eclipse 的要求太多了，为了获得内置的 Web 应用程序功能，它不能来自 Maven？
There is one other I could try. I could create a Dynamic Web App in Eclipse, then hit "Convert to Maven" . Take that POM, modify, then see if netbeans will also load it.
还有一个我可以试试。我可以在 Eclipse 中创建一个动态 Web 应用程序，然后点击 "Convert to Maven" 。拿那个 POM，修改，然后看看 netbeans 是否也会加载它。

As suggested by jhericks ,if you use m2eclipse, you don't need to use eclipse:eclipse goal. What the eclipse:eclipse goaldoes can also be done by the m2eclipse.
正如 jhericks 所建议的，如果您使用m2eclipse，则不需要使用eclipse:eclipse goal. 什么eclipse:eclipse goal做，也可以由m2eclipse的完成。
To convert a project to the Dynamic Web Application , you can configure the Project Facetsoptions in your project properties
要将项目转换为动态 Web 应用程序，您可以Project Facets在项目属性中配置选项

I have had better luck with the m2eclipse pluginfrom Sonatype. When I started, I made the mistake of trying to use both m2eclipse and the eclipse:eclipse goal. They don't do exactly the same thing, so if you install the plugin, stop doing mvn eclipse:eclipse. Anyway, it has worked very well for me with single web projects and very well with multi-project reactor style projects as well.
我使用Sonatype的m2eclipse 插件运气更好。当我开始时，我犯了一个错误，试图同时使用 m2eclipse 和 eclipse:eclipse 目标。他们做的事情并不完全一样，所以如果你安装了插件，停止执行 mvn eclipse:eclipse。无论如何，它对我来说非常适合单个 Web 项目，也非常适合多项目反应器风格的项目。
The only problem I've had is with trying to deploy a war file to a server configured in eclipse if that war file is built with an overlay, but that doesn't seem to be an issue for you.
我遇到的唯一问题是，如果该War文件是使用覆盖层构建的，则尝试将War文件部署到在 eclipse 中配置的服务器，但这对您来说似乎不是问题。

m2e-wtpplugin does this automatically, as stated here: Import Existing Maven in Eclipse as WTP
m2e-wtp插件会自动执行此操作，如下所述：Import Existing Maven in Eclipse as WTP
All facets, source folders etc will be correctly set after import.
导入后将正确设置所有方面、源文件夹等。
