如何从maven中的外部jar复制资源？

Question

我有一个基于 maven 的多模块项目，其模块结构如下：

--

 --A

   pom.xml

 --B

   pom.xml

-pom.xml

我在父.pom 文件中添加了一个依赖项。现在我想使用来自A模块中添加的依赖项的资源。

有没有办法使用 maven仅将外部资源复制到A模块？

我尝试为此使用maven-remote-resources-plugin，但它没有看到外部资源。

Answer 1

所以我找到了下一个解决方案。它不是最佳的，但它可以工作并且可以做我想要的。它从外部 jar（maven 依赖）中提取资源文件并将其复制到类路径资源中。这不是最佳选择，因为我必须在文件移动到所需位置后删除空目录。<build>&nbsp; &nbsp; &nbsp; &nbsp; <plugins>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <plugin>&nbsp;

Answer 2

您必须向应该使用它的模块添加依赖项。然后你可以使用maven 依赖插件从该依赖中获取资源。
