很遗憾，我在启动应用程序时收到以下错误：

请注意，我可以使用引用的 .bndrun 文件从 Eclipse 中很好地启动应用程序，并且在使用 gradle 时会很好地生成应用程序。
我用来构建这个可运行jar文件的maven命令简单如下：
mvn clean package
我进一步提取了可运行 jar 文件的内容，下面显示了嵌入的 jar 文件。
所以很明显，所需的 jar 文件没有放入可运行的 jar 文件中。但我不清楚这是为什么。
但是，我正在从 gradle 过渡到 maven，并且似乎被困在最后一项上。解决指针表示赞赏。
谢谢， 兰迪
【问题讨论】：
-
你使用哪个版本的 bnd maven 插件？
-
我使用的是 v4.3.1。注意 groupId 是 biz.aQute.bnd，而不是 org.apache.felix。关于后一点，不确定哪个是首选。
