Running the script without ide

How can I run a script without launching ide application?
I open ide by command "java -jar /path/sikulixide-2.0.5-lux.jar", then press File -> Export as runnable jar. A window appears stating that it has been saved to name_of_script.jar. Also in the ide application in the message field is written: Compiling /root/.Sikulix/SikulixStore/SikulixTemp/scriptCompiled/name_of_script.py ...
SyntaxError: ("Non-ASCII character in file '/root/.Sikulix/SikulixStore/SikulixTemp/scriptCompiled/name_of_script.py', but no encoding declared; see http://www.python.org/peps/pep-0263.html for details",)

In this case, the first line of the script is # coding=utf-8

If i enter java -jar name_of_script.jar - an error will appear:

[Error] sikulix....jar not specified and not found elsewhere

Help please.
