From 66ea26b1bc7bbc8d54a3498dbd3d0919c4712fa8 Mon Sep 17 00:00:00 2001 From: Marek Gradzki Date: Tue, 26 Jul 2016 15:28:22 +0200 Subject: VPP-205: jvpp plugin support. Splits jvpp into two jars jvpp-registry.jar - base jvpp functionality jvpp-core.jar - Java wrapper for vpe.api Plugins can be generated the same way jvpp-core.jar is.
