Executing java class in correct directory

I cannot seem to run my java program because it thinks my MO.class file is in the classpath for my gson library. What am I doing wrong?

$ ls
gson MO.java

$ javac -cp .:gson/gson/target/gson-2.7.1-SNAPSHOT.jar MO.java

$ java -cp .:gson/gson/target/gson-2.7.1-SNAPSHOT.jar MO

Remove the line package com.google.gson; from your file MO.java. Also, you need to compile your program before you can run it. It looks like you didn't, since there is no file MO.class in your directory. - Jesper
