我有一个关于maven-assembly-plugin和maven-jar-plugin的执行顺序的问题。我想要做的是将一个uberjar文件放在一起构成框架（java的插件框架）。为了能够做到这一点，我需要首先将所有代码与依赖关系进行汇编，然后将清单文件打包到清单文件中，清单文件具有框架所需的特定条目。 在问题"Changing the order of maven plugin execution" 我读到的答案是，绑定到同一阶段的插件的顺序是由在pom.xml文件中声明的顺序定义的。现在，我有以下pom.xml文件：maven-assembly-plugin和maven-jar-plugin的执行顺序

从pom.xml文件应该很清楚，我想以后Maven的组装插件运行Maven的JAR-插件。而是我得到以下Maven输出：

现在从输出可以看出，Maven的JAR-插件的Maven的组装插件，这不是我想要的东西之前执行。这样的订单的效果是只有MANIFEST_INF内容的jar文件。
有人可以解释我在这里做错了什么？
