[英]Maven Multi Module Resource Sharing
I have a Maven structure that builds just fine, but I somehow struggle with my Checkstyle resources. 我有一个可以很好构建的Maven结构,但是我却在某种程度上难以使用我的Checkstyle资源。 The structure is as follows:
结构如下:
The parent is supposed to define everything that both sub parents have in common. 父母应该定义两个子父母共同拥有的一切。 The Checkstyle plugin has the "Build Resources" as a dependency.
Checkstyle插件具有“构建资源”作为依赖项。 The is defined as "/checktyle_resources/checkstyle.xml".
的定义为“ /checktyle_resources/checkstyle.xml”。 I have problems with my Checkstyle plugin, because it can't find the neccessary resources, if I build the "Parent".
我的Checkstyle插件存在问题,因为如果我构建了“父代”,则找不到所需的资源。 If I build "Sub Parent A" or "Sub Parent B", checkstyle works fine, but of course the "Build Resources" have to be installed to the repository priorly.
如果我构建“子父级A”或“子父级B”,则checkstyle可以正常工作,但是当然必须事先将“构建资源”安装到资源库中。
Has somebody an idea why this won't work? 有人知道为什么这行不通吗? Is this Maven structure even a good idea?
这个Maven结构甚至是个好主意吗?
Thanks 谢谢
PS: I have seen this question. PS:我已经看到了这个问题。 And in the way the answer describes the solution it works in my project fine.
并以答案的方式描述了可以在我的项目中正常工作的解决方案。 But my multi-layered parent structure seems to create some kind of an issue here.
但是我的多层父结构似乎在这里造成了某种问题。
Here is the related content of the pom.xml of the parent. 这是父级的pom.xml的相关内容。

Thanks for your help Tome and Chrylis. 感谢您的帮助Tome和Chrylis。
The solution was indeed to remove the checkstyle-plugin from the -section of my parent-pom and put it in the sub-parent poms, while the configuration of the plugin is defined in the -section of the parent. 解决的方法的确是从父pom的-节中删除checkstyle-plugin并将其放在子父poms中,而插件的配置在父pom的-节中定义。
Now I still have checkstyle execution for the sub-parents when I build the Parent only and I don't have the redundancy of configuring it in every module individually. 现在,当我仅构建父级时,我仍然可以为子父级执行checkstyle执行,而我没有多余的冗余在每个模块中分别进行配置。
