Hi,I have read the dependency document;
I want to use jnetpcap in my project.
I edited the build.gradle by adding compile ':jnetpcap' to dependencies {}.
And while I run the command "./s4 s4r -a=hello.HelloApp -b=`pwd`/build.gradle myApp",it showed
"build successful".
However,while the project was running,it came below errors:

10:39:18.003 [itoa] ERROR org.apache.s4.core.S4Node - Uncaught exception in thread itoa

I don't know what caused the error.I check the *.jar file compiled by the s4r command.In the
*.jar file ,there is class org.jnetpcap.packet.PcapPacket in jnetpcap.jar file.

If your dependency is not in the standard maven repository, make sure it is in the lib directory.

The jnetpcap.jar file must be embedded in the generated s4r file, can you make sure this is
the case (just unzip to check)?
