从依赖于 Shade 或 Maven Assembly Plugin 的 Maven 项目构建可执行 Jar

Question

我正在尝试创建一个打包了依赖项的可执行 jar。到目前为止，我一直收到“无主要清单属性”。有谁知道我做错了什么？

我在 POM 的顶部添加了包装 jar

  <groupId>com.moga</groupId>
  <artifactId>capacityplanfacilities</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

根据文档，这是我测试过的 2 种方法（Maven Shade 和 Apache Maven Assembly）：

    <!--    Do not work for when running tests-->

问题正在通过修改清单的路径解决。我在 Intellij 中测试了 Manifest 文件的内置生成，发现问题可能与 Manifest 的位置有关，我添加到与 pom 相同的级别，而 intellij 设置在 java 文件夹中.
