Maven的OSGi的项目编译，但不会跑

Question

我一直在试图端口Paul Bakker's（@保罗 - 贝克）Making JavaFX better with OSGi : javafx-osgi-example到使用Apache Maven的菲利克斯捆绑插件（BND）一个maven OSGi的项目。到目前为止，它编译没有任何错误，但我不能得到它运行：

Starting OSGi Framework 
Found declarative services implementation: file:/C:/Users/Rev/.m2/repository/org/apache/felix/org.apache.felix.scr/1.6.2/org.apache.felix.scr-1.6.2.jar 
INFO : org.apache.felix.scr (1): Version = 1.6.2

    Registered service: [org.apache.felix.scr.impl.ScrGogoCommand] 
DEBUG: Starting ComponentActorThread 
Bundle: null 
Bundle: null 
Bundle: null 

正如你所看到的，捆绑从未开始。没有错误被抛出。它只是根本不启动。

为什么捆绑不会启动？

项目源

1. Paul Bakker's (The original non-maven project) : javafx-osgi-example

2. My maven implementation of Paul Bakker's javafx-osgi-example : JavaFX-Maven-Multi-Module-OSGi

从终端（Windows），mvn clean install完美工作。

UPDATE

我一直在试图从Eclipse中运行它，但没有成功：

运行 - >运行为 - > Java应用程序

---

适用于Web开发人员的Eclipse Java EE IDE。

版本：Mars.2版本（4.5.2）
版本ID：20160218-0600

UPDATE

我有一个类在App下DIST打包rev.dist启动。它会循环通过rev下的所有目录，并启动名称与resources/plugins.txt下的名称相匹配的任何罐子。

我已经发布了几个Drombler FX第一早期Access版本的 - JavaFX的模块化应用程序框架。

它不是基于Paul Bakker的工作，而是基于OSGi和Maven（POM-first）。也许你觉得它很有用。应用程序框架是开源的。

还有一个tutorial与Getting Started页面。
