java - 是否可以使用 org.codehaus.mojo :build-helper-maven-plugin to bundle native dlls into a war file?

Question

我有一组用maven构建的java项目。

现在，其中一个依赖于 native DLL，而 native DLL 又依赖于其他几个，所有这些都是我构建的。构建的最终产品是一个 war 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 作为各自 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。

但我正在尝试探索另一种方法，不确定是否只有我做错了，或者根本不可能。我正在谈论 org.codehaus.mojo:build-helper-maven-plugin 的 attach-artifact 目标。

这是我尝试的方法:

根级别pom.xml:

运行mvn package成功，创建了war文件，但它不包含任何 native DLL。这些 DLL 构建得很好，但它们永远不会被复制到任何地方。

我运行了mvn -X。以下是我认为相关的几行:

我对maven不太熟悉，所以我可能省略了日志中的重要部分。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，但占用了大量空间)

所以我的问题是 - 我可以使用 org.codehaus.mojo:build-helper-maven-plugin 来完成我需要的操作 - 将 native DLL bundle 到 war 中吗？

编辑

我已经尝试了SpaceTrucker建议的方法，没有产生任何错误，但由此产生的 war 仍然是一样的——没有打包DLL。 maven 日志包含以下条目:

日志提到local-driver-proxy-0.0.1.dll，但该文件不存在!

Answer 1

从我在你的pom中看到的是，没有从Java项目声明依赖关系，该项目构建了对包含 native dll的项目的 war 。声明此依赖项时应该没问题。

编辑:
将其添加到 war 文件 pom 的 dependency 部分:

<dependency>
  <groupId>com.shunra.localDriverProxy</groupId>
  <version>0.0.1</version>
  <artifactId>local-driver-proxy</artifactId>
  <classifier>DataStruct</classifier>
  <type>dll</type>
</dependency>
