如何在 Eclipse 中配置 Java EE maven 项目？

How do I configure a Java EE maven project in Eclipse?

提问by javabeats

I know Maven pretty well, but I usually work with Netbeans, which makes it quite easy to deploy Java EE applications - and handle hot deployment of any changes.

我非常了解 Maven，但我通常使用 Netbeans，这使得部署 Java EE 应用程序变得非常容易 - 并处理任何更改的热部署。

The team I work with now uses Eclipse as their IDE of choice, but none of them has worked with Maven projects before; so I need to know how to correctly add Eclipse's project facets to the maven projects we have, in order to support (hot) deployment through WTP. We are using Weblogic 12c for this particular endeavour.

我工作的团队现在使用 Eclipse 作为他们选择的 IDE，但他们之前都没有使用过 Maven 项目；所以我需要知道如何将 Eclipse 的项目方面正确添加到我们拥有的 Maven 项目中，以便通过 WTP 支持（热）部署。我们正在使用 Weblogic 12c 来完成这项特殊的工作。

Our project layout is as simple as it gets:

我们的项目布局非常简单：

super-project (pom)
    project-ear (pom)
    project-ejb (pom)
    project-web (pom)

Thanks for any resource you can point me to.

I suppose that you've installed all required plugins to the Eclipse already. As @Micha? Politowski mentions, M2E, M2E-WTPand so on.

Summary

I've used both NetBeans 7.x and Eclipse Juno together. When I move to Eclipse I've face the issue as same as your. Then I've captured the steps above from NetBeans logs one by one, and do the same thing manually by using Eclipse.

I hope this may help.

I would make one small change:

我会做一个小的改变：

Create the child project

创建子项目

Right click at the parent project and select New ---> Other.
    At the Select Wizard Windows, select Maven ---> **Maven Module**

This way it will automatically recognize this as a child project of the parent.

这样它会自动将其识别为父项目的子项目。
