this should avoid the error produce in jenkins 
```
[error] /localhome/jenkinsakka/workspace/akka-pr-validator/akka-osgi/src/main/scala/akka/osgi/ActorSystemActivator.scala:90: not found: type Config
[error]   def getActorSystemConfiguration(context: BundleContext): Config = ConfigFactory.empty
[error]                                                            ^
[error] /localhome/jenkinsakka/workspace/akka-pr-validator/akka-osgi/src/main/scala/akka/osgi/ActorSystemActivator.scala:90: not found: value ConfigFactory
[error]   def getActorSystemConfiguration(context: BundleContext): Config = ConfigFactory.empty
[error]                                                                     ^
[error] two errors found```
Do I need to change this import position?
