无法打包插件

不幸的是，包括相关的罐子作为外部罐子不允许我成功创建插件所以我尝试（按照 vogella 上的建议）导出目标平台并创建一个父 pom 并在其中放置我的插件项目和另一个使用目标平台管理依赖项的项目：

这是因为依赖项之一，即 org.apache.log4j_1.2.17.2019-11-22 实际上是一个 ddirectory，里面有一个 log4j-lib 插件。当 运行 在 IDE 中设置项目时，这很好用，但我不知道如何正确解决这个问题。任何帮助将不胜感激！
所以实际的解决方案是使用现有的 jar 存档选项创建一个新插件。将该插件作为依赖项添加到我的插件中，并将其添加到模块部分的 parent pom.xml 中。需要对依赖项进行一些修改，但将生成的构建 jar 文件添加到 dropins 文件夹目前似乎已经奏效了。
