I'm trying to run this project (voicerecog4pi-master.zip)

thsi is my paste of the raspberry pi:

root@raspberrypi:/opt# ls
jdk1.8.0_06 MQTTBaseClass.java pi4j vc
jdk8 mqtt-client-0.4.0.jar sonic-pi Wolfram

When I tried this command:

javac -cp mqtt-client-0.4.0.jar MQTTBaseClass.java

I have this errors:

root@raspberrypi:/opt# javac -cp mqtt-client-0.4.0.jar MQTTBaseClass.java

Looks like a issue with oracle compiler.

>javac -cp mqtt-client-0.4.0.jar MQTTBaseClass.java

Have you tried ecj (command line version of the Eclipse Compiler).
