I'm using Eclipse Luna. I'm working on a Maven project. When I try to run my application on a weblogic's application server, and exception is thrown with the message:
我使用Eclipse Luna。我正在做一个Maven项目。当我试图在weblogic的应用服务器上运行应用程序时，会抛出以下消息:
weblogic.application.ModuleException: [HTTP:101027][WebAppModule(_auto_generated_ear_:MyAppName)] Document root: "D:\MGelbana\workspace\my-app-name\target\m2e-wtp\web-resources" does not exist.
I looked into the project's deployment assembly configuration and found the following error message: Cannot find entry: "/target/m2e-wtp/web-resources"
我查看了项目的部署程序集配置，发现以下错误消息:找不到条目:“/target/m2e-wtp/web资源”
So I thought Luna's default Maven installation isn't what I need to I uninstalled it and I installed M2E-WTP from this URL (http://download.eclipse.org/m2e-wtp/releases/luna/) but I believe I ended up with the same version and same options.
因此，我认为Luna的默认Maven安装不是我需要的，我卸载了它，并从这个URL (http://download.eclipse.org/m2e-wtp/releases/luna/)安装了M2E-WTP，但我相信我最终得到了相同的版本和相同的选项。
I understand that this plugin has the option of generating this folder /target/m2e-wtp/web-resources which helps Eclipse to deploy an application into an application server (Run on server option)
我理解这个插件可以生成这个文件夹/目标/m2e-wtp/web资源，它可以帮助Eclipse将应用程序部署到应用服务器(运行在服务器上)
(Which is my end goal but I'm having issues with deploying the application with it's needed dependencies. If I generate the application's WAR file by
Installing the maven project and deploying the generated that WAR manually, the application works, but I need to be able to debug\run it on the application server using Eclipse.)(这是我的最终目标，但我在部署应用程序时遇到了需要依赖项的问题。如果我通过安装maven项目并手动部署生成的WAR来生成应用程序的WAR文件，那么这个应用程序可以工作，但是我需要能够使用Eclipse在应用服务器上调试\运行它)。
But this folder (i.e. /target/m2e-wtp/web-resources) isn't created !
但是这个文件夹(例如/target/m2e-wtp/web资源)没有创建!
In Eclipse's Maven > Java EE Integration > WAR project preferences > Maven archiver generated files under the build directory (I checked this option)
在Eclipse的Maven > Java EE集成> WAR项目首选项> Maven归档程序中，在构建目录下生成文件(我选中了这个选项)
In the project-specific options, I only have a Maven menu and a Lifecycle mapping sub-menu and nothing to do with the maven archiver generating files or not !
在特定于项目的选项中，我只有一个Maven菜单和一个生命周期映射子菜单，与Maven归档文件生成文件没有任何关系!
So how can I direct maven to output the WTP related files ?
那么如何指导maven输出与WTP相关的文件呢?

I was struggling with the same issue for couple of days. Ultimately following worked for me.
我为同样的问题挣扎了几天。最终，跟随别人对我起了作用。
- Install m2e-wtp from eclipse marketplace (if it's not already installed)
- 从eclipse市场安装m2e-wtp(如果还没有安装的话)
- Open project preferences -> Project Facets -> Runtimes -> Select the runtime of your choice (Tomcat 7 in my case)
- 开放项目首选项->项目facet ->运行时->选择您选择的运行时(在我的例子中是Tomcat 7)

Eclipse (Luna) will only generate the Maven Archiver files under the build path (in /target/m2e-wtp/web-resources) if it considers the project to be a "WAR Project".
如果将项目视为“战争项目”，Eclipse (Luna)只会在构建路径(in /target/m2e-wtp/web资源)下生成Maven Archiver文件。
From experience, this seems to be any project with the Dynamic Web Module facet. If the project is already a Faceted Form project, add the facet and build your project. If not, choose the [Configure -> Convert to Faceted Form...] menu option and go from there.
从经验来看，这似乎是任何具有动态Web模块方面的项目。如果项目已经是一个多面的表单项目，那么添加facet并构建项目。如果不是，选择[配置->转换为面形…菜单选项，然后从那里开始。
For projects imported as "Existing Maven Projects", Eclipse will usually set this for you. But if you've just checked the project out of version control or created / imported the project as a "standard" Java project, it may not have done.
对于作为“现有Maven项目”导入的项目，Eclipse通常会为您设置这个。但是，如果您只是在版本控制之外检查了项目，或者将项目作为“标准”Java项目创建/导入，那么它可能还没有完成。

Nothing wrong with the tomcat plugin or the application, it only needed a refresh once in a while. Also, because maven was cleaning up target. I just had to setup my maven build to also refresh the project including target folder.

Just spend a couple of hours trying every solution described in this lengthy thread... Nothing worked until I discovered something hidden in the preferences...

The solution was simple: Preferences -> Maven -> Java EE Integration -> Enable Java EE configuration
