Hi Ashish,
A regular JAR can be put into lib directory and it will be automatically
converted to an OSGi bundle by the system. If we have an OSGi bundle then
we need to put it into the dropins directory.
To add a custom layout plugin, first we need to build the plugin as an OSGi
fragment and make its content available to the
org.ops4j.pax.logging.pax-logging-log4j2 host bundle. As we are building an
OSGi bundle we need to put it into dropins directory not in lib directory.
Regards,
Srivathsan
