java - 如何使用 maven 程序集从 jar 中包含资源(css，js)？

Question

我有一个项目，其中包含多个子项目的共享资源；即除了 Java 代码外，它还包含 css 和 javascript。

我的子项目使用 maven 程序集插件打包为 jar。由于某些原因，这些不包括父库中的 css 和 js 资源。

所以我的问题很简单:如何配置项目才能实现这种情况？我不希望子项目成为 war ；它们是作为独立 jar 运行的 dropwizard (/jetty) 项目。

编辑 - 我应该明确指出资源包含在父项目的 jar 中；只有当程序集(在子项目上)包含它们以某种方式丢失的 jar 时。

Answer 1

So my question is simple: how can I configure the projects so that this happens? I don't want the child projects to be wars; they are dropwizard (/jetty) projects that run as standalone jars.>

需要在<resource></resource>中添加资源目录以便它在构建 jar 时拾取

您可以使用 maven-assembly 插件或配置您的 pom.xml 以将这些资源文件指定为 maven 资源，assembly plugin会给你更多的灵 active
