Maven多模块资源共享



我有一个Maven结构,它构建得很好,但不知何故,我很难使用Checkstyle资源。结构如下:

  • 家长
    • 子母公司A
      • 模块
    • 子母公司B
      • 模块
    • 构建资源
      • src/main/resources文件

父项应该定义两个子父项的所有共同点。Checkstyle插件具有"构建资源"作为依赖项。定义为"/checkstyle_resources/checkstyle.xml"。我的Checkstyle插件有问题,因为如果我构建"Parent",它找不到必要的资源。如果我构建"Sub-Prental A"或"Sub-Pparent B",检查样式可以正常工作,但当然"构建资源"必须先安装到存储库中。

有人知道为什么这不起作用吗?这种Maven结构是个好主意吗?

感谢

附言:我看过这个问题。从答案描述解决方案的方式来看,它在我的项目中很好。但我的多层家长结构似乎在这里制造了某种问题。

以下是父级的pom.xml的相关内容。

感谢您的帮助Tome和Chrylis。

实际上,解决方案是从我的父pom的-部分中删除checkstyle插件,并将其放在子父pom中,而插件的配置则在父的-部分定义。

现在,当我只构建Parent时,我仍然可以执行子父级的检查样式,并且我没有在每个模块中单独配置它的冗余。
