我有一组用 maven 构建的 java 项目。
现在其中一个依赖于本机 DLL，而后者又依赖于其他几个，我也构建了所有这些。构建的最终产品是一个战争文件。我需要将这些 dll 放在该 war 文件中。
我知道一种方法是将这些 dll 作为相应 java 项目的资源包含在内。这样做意味着我必须在构建该项目之前将这些 dll 复制到相应 java 项目的资源目录中。
但我正在尝试另一种方式，不确定是我做错了还是根本不可能。我说的是attach-artifact目标org.codehaus.mojo:build-helper-maven-plugin。
这是我尝试的方法：

运行mvn package成功，war 文件已创建，但它不包含任何本机 DLL。这些 DLL 构建得很好，但它们永远不会被复制到任何地方。
我跑了mvn -X。以下是我认为相关的行：

我对 maven 不是很熟悉，所以我可能从日志中省略了重要部分。完整的日志在这里 - http://pastebin.com/raw.php?i=fhZCmGxB（我删除了其他几个 java 项目的构建日志，它们看起来都一样，但占用大量空间）
所以我的问题是 - 我可以使用org.codehaus.mojo:build-helper-maven-plugin来做我需要的 - 将本机 DLL 捆绑到战争中吗？
编辑
我已经尝试了 SpaceTrucker 建议的方法，没有产生错误，但产生的战争保持不变 - 没有打包 DLL。maven 日志包含以下条目：
