Problem with Eclipse and a Maven multi-module project
提问by earth
I have created a Maven project with the following structure:
我创建了一个具有以下结构的 Maven 项目：
+ root-project pom.xml (pom) + sub-projectA (jar) + sub-projectB (jar)
I have done the following steps:
我已经完成了以下步骤：
- mvn archetype:create –DgroupId=my.group.id –DartifactId=root-project
- mvn archetype:create –DgroupId=my.group.id –DartifactId=sub-projectA
- mvn archetype:create –DgroupId=my.group.id –DartifactId=sub-projectB
- mvn 原型：创建 –DgroupId=my.group.id –DartifactId=root-project
- mvn 原型：创建 –DgroupId=my.group.id –DartifactId=sub-projectA
- mvn 原型：创建 –DgroupId=my.group.id –DartifactId=sub-projectB
So I have, obviously, in the top-level pom.xml the following elements:
因此，显然，在顶级 pom.xml 中，我有以下元素：
<modules>
<module>sub-projectA</module>
<module>sub-projectB</module>
</modules>
The last step was:
最后一步是：
mvn eclipse:clean eclipse:eclipse
Now if I import the root-projectin Eclipse, it seems to look at my projects as resources and not like java projects.
现在，如果我在 Eclipse 中导入根项目，它似乎将我的项目视为资源而不是 java 项目。
However if I import each of child projects sub-projectAand sub-projectB, it looks them like java projects.
但是，如果我导入每个子项目 sub-projectA和sub-projectB，它们看起来就像 java 项目。
This is a big problem for me because I have a deeper hierarchy. Any help would be appreciated!
这对我来说是一个大问题，因为我有更深的层次结构。任何帮助，将不胜感激！

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).
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（除非您移动到平面布局）。
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.
另一种方法是使用m2eclipse（使用maven 典型的嵌套树不会有任何问题）。这是当今的首选方法。

使用此命令将 simple-parent 转换为 eclipse 项目
mvn eclipse:eclipse
Import sample-parent in eclipse.
For runing this project
right click on simple-webapp->properties->deployment assemblly->project-> Then add all the dependent project.
Now you can run this project.
在eclipse中导入sample-parent。

I had a similar issue, and the following is what I did to solve it...
我有一个类似的问题，以下是我为解决它所做的......
I had the parent project open as well as the child projects. The child projects would build fine and not show any problems, however the parent showed the child projects as "resource folders" and they showed as having problems.
我打开了父项目以及子项目。子项目可以正常构建并且不会显示任何问题，但是父项目将子项目显示为“资源文件夹”并且它们显示为有问题。
Solution was to right click on each of the child projects in the parent project -> Properties -> Resource -> Check "derived"
解决方案是右键单击父项目中的每个子项目 -> 属性 -> 资源 -> 选中“派生”
After you do this, clean/rebuild and you should be good.
执行此操作后，清理/重建，您应该会很好。
