我一直在尝试将Paul Bakker's( @ paul-bakker )Making JavaFX better with OSGi : javafx-osgi-example移植到使用Apache Felix Maven Bundle Plugin(BND)的maven OSGi项目中。到目前为止,它编译没有任何错误,但我无法运行:
Starting OSGi Framework

正如您所看到的,捆绑包永远不会开始。没有错误被抛出。它根本就没有开始。
为什么捆绑包会开始?
项目来源
从终端(Windows),mvn clean install工作正常。

我一直试图从Eclipse运行它,但没有成功:

我在启动时的App
包中的 dist 下有一个rev.dist
课程。它循环遍历 rev 下的所有目录,并启动任何名称与resources/plugins.txt
下的名称相匹配的jar。

我已经发布了几个早期版本的Drombler FX - JavaFX的模块化应用程序框架。
它不是基于Paul Bakker的作品,而是基于OSGi和Maven(POM-first)。也许你发现它很有用。应用程序框架是开源的。
