[Solved] Problem running final mod due to lib dependancies


Recommended Posts

Hi all,


Unfortunately I am not a java expert, but generally software aware. I have a fully functional mod when building / running from eclipse. I have a set of specific jar libs that I had to add as external dependancies for some websocket behaviour. I did this via Java Build Path \ libraries.


Everything there builds and runs fine.


I am in the final steps of wanting to be able to just provide a final jar file, dropping it in the mod folder of a minecraft installation and all magically working.


However, using the "gradlew build" method from the command line to generate my final jar file, the libs required are not resolved at run time in a clean minecraft installation ( even on the same machine ) so I get not found errors.


I have these in my gradle.build


dependencies {

compile 'org.eclipse.jetty.websocket:websocket-api:9.3.5.v20151012'

compile 'org.eclipse.jetty.websocket:websocket-client:9.3.5.v20151012'

compile 'org.eclipse.jetty.websocket:websocket-common:9.3.5.v20151012'



I have also tried having them directly in the libs directory and it also builds fine, but at runtime I always get the following error...


java.lang.NoClassDefFoundError: org/eclipse/jetty/websocket/client/WebSocketClient


How do I encapsulate these jar libs into my mod so they can be found at runtime....


Any help greatly appreciated, been trying to resolve this for a while now. I would settle for knowing where I can drop copies of the libs so it just runs right now :-(

Huge thanks, once I had realized that shading was a built in behavior rather than a plugin, and managed to interpret the instructions ( and get them at the end of my gradlew.build file ) then everything just works. I had been down many dead ends before this.


My head thanks you! It was getting bruised with all the wall banging it had been doing!
