带有maven shade插件的父子pom答案

【问题标题】：Parent and child pom with maven shade plugin带有maven shade插件的父子pom
【发布时间】：2021-12-13 04:11:06
【问题描述】：

我有一个带有 pom 的父 maven 项目和两个带有 jar 模式包装的 pom 的子项目。这两个子 pom 都有一个启动类。问题是每次创建新的子项目时，都需要一个带有jar包装的新pom。研究目标是创建一个jar打包模式的父pom，去掉MyChildLauncherCLass声明，规范每个子pom的版本。

我怎么能在上面的父 pom 上做到这一点

【问题讨论】：

我会尝试在你的父 POM 中使用 <pluginManagement>。
删除<sourceDirectory>../../webapp/src/main/java</sourceDirectory>，因为你做错了...请在 GitHub 或类似网站上制作一个完整的工作示例...
嗨 @GeroldBroser 在我的父包中我有 atori-batchpom${project.artifactId}。我想将包装 pom 更改为 jar 包装，并添加带有标签的 shade 插件，以便为每个孩子提供特定版本
嗨 @khmarbaise 在我的父包中我有 atori-batchpom${project.artifactId}。我想将包装 pom 更改为 jar 包装，并添加带有标签的 shade 插件，以便为每个孩子提供特定版本
仅使用 maven-shade-plugin 的配置创建一个单独的子级，并将所需的子级添加为依赖项。您不能将父包装从 pom 更改为 jar，因为这不适用于多模块构建...
