Support for windows

Is your feature request related to a problem? Please describe.
Unable to run ec.jar in windows

Describe the solution you'd like
Should be able to use "java -jar %EC_COMPILER_HOME%\target\ec.jar %*" in windows instead $@

Describe alternatives you've considered
Tried powershell and prompt. Build entity-compiler from develop branch but still not able to make it work

Additional context
I think there is some hardcoded reference to the path that is restricting this to be used in windows.
