Hi Andrew,
Here's the exception I get while trying to build an OSGi bundle using maven SCR
plugin -
[ERROR] Failed to execute goal org.apache.felix:maven-scr-plugin:1.9.0:scr
(generate-scr-scrdescriptor) on project repo-spark: Execution

Also, from eclipse, if I build a simple main program. Then, I can create an
executable JAR in 3 ways -
a. Extract required libraries into generated JAR ( individual classes
inside my JAR)
On running main program on this JAR –
Exception in thread "main" com.typesafe.config.ConfigException$Missing: No
configuration setting found for key 'akka.remote.log-received-messages'
at com.typesafe.config.impl.SimpleConfig.findKey(SimpleConfig.java:126)
at com.typesafe.config.impl.SimpleConfig.find(SimpleConfig.java:146)
b. Package required libraries into generated JAR (all JARs inside my JAR)
On running main program on this JAR –
Exception in thread "main" java.lang.reflect.InvocationTargetException

c. Copy required libraries into a sub-folder next to generated JAR
This works well ! But problem is that it’s not portable to a java server.
