Run Compiler

It compiles but no result return, unfortunately we could run it with absolute path to the arguments.

mvn exec:java -Dexec.mainClass="Compiler" -Dexec.args="absolute address\arg1 arg2"

the following command for runtime but also no result return

mvn exec:java -Dexec.mainClass="Compiler" -Dexec.classpathScope=runtime
