How do I compile Jicofo from source?

Question

I've previously installed Jicofo using sudo apt install jitsi-meet, but now I want to change some things so I'm trying to compile Jicofo from source.

I did mvn clean compile package -DskipTests and it created a JAR file. I then replaced /usr/share/jicofo/jicofo.jar with this file and ran sudo service jicofo restart, but now when I try to join a room in my browser the video never connects. I get an error in my jicofo.log file:

Just to make sure that I'm not suffering from XY Problem I'll quickly explain some background. I'm trying to get Jitsi Meet to run on a Raspberry Pi, but the Raspberry Pi only supports h/w acceleration for h264, not VP8. When I set preferH264 in Jitsi Meet's settings it works, but I can no longer use Jitsi in Google Chrome. It seems this may be caused by a case-sensitivity issue, so I'm trying to apply the patch found here (https://github.com/jitsi/jitsi-meet/issues/877#issuecomment-269054479). That's why I'm trying to compile from source.

I'm not experienced with Java so my apologies if I'm missing something obvious.

Answer 1

I got some help from the Jitsi Users mailing list. The issue was out of date dependencies. The solution was to build it using the following line:

mvn -U clean compile package -DskipTests -Dassembly.skipAssembly=false

and then extract the generated zip file and copy all the contents into /usr/share/jicofo.
