Eclipse和Maven多模块项目的问题 [英] Problem with Eclipse and a Maven multi-module project

问题描述

我已经创建了一个具有以下结构的Maven项目：

I have created a Maven project with the following structure:

+ root-project
  pom.xml (pom)
  + sub-projectA (jar)
  + sub-projectB (jar)

我已经完成了以下步骤：

I have done the following steps:

1. mvn archetype：create -DgroupId = my.group.id -DartifactId = root-project


2. mvn archetype：create -DgroupId = my.group.id -DartifactId = sub-projectA


3. mvn archetype：create -DgroupId = my.group.id -DartifactId = sub-projectB

显然，在顶级的pom.xml中有以下元素：

So I have, obviously, in the top-level pom.xml the following elements:

  <modules>
    <module>sub-projectA</module>
    <module>sub-projectB</module>
  </modules>

最后一步是：

mvn eclipse:clean eclipse:eclipse

现在如果我导入根项目在Eclipse中，似乎将我的项目看作是资源而不是java项目。

Now if I import the root-project in Eclipse, it seems to look at my projects as resources and not like java projects.

但是，如果我导入每个子项目子项目A 和子项目B ，它看起来像java项目。

However if I import each of child projects sub-projectA and sub-projectB, it looks them like java projects.

这是一个很大的问题因为我有一个更深层次的层次。任何帮助将不胜感激！

This is a big problem for me because I have a deeper hierarchy. Any help would be appreciated!

推荐答案

maven eclipse插件不支持嵌套项目，因此您无法导入根项目和嵌套模块（除非您转到平面布局）。

The maven eclipse plugin does NOT support nested projects so you can't import the root-project and the nested modules (unless you move to a flat layout).

另一种方法是使用 m2eclipse （而且你不会有一个maven典型的嵌套树有任何问题）。这是现在的首选方法。

The alternative is to use m2eclipse (and you won't have any problems with a maven-typical nested tree). This is the preferred approach nowadays.
