Exception in thread "main" ImportError: No module named __run__

How did you create that "script"-jar?

I have version 1.1.2 so I went to File-> Export as runnable jar.

I also tried creating the script using the command: java -jar sikulixsetup-1.1.2-....jar scriptjar <path-to-your-script> and when I am trying to run it I get a different error.

Exception in thread "main" Traceback (most recent call last):

Sorry, but the feature is no longer supported and even switched off in 1.1.4

So, is there any other way to run the script without installing SikuliX?

Sorry, no currently.

... but with 1.1.4, there is no longer a setup needed.

If you want to run scripts, you need a valid Java and have to download 2 jars.

If you create your workflows with Java code, you could pack your own complete runnable jar (be aware: the resulting jar would be up to 80MB!)

There should be another entry in the File menu: Export as jar

This creates a jar, that contains the compiled sources and the images and can be run with plain Jython having sikulixapi.jar on the class path at runtime.
jyton -jar your script.jar

another option (not having a Jython environment installed) (only supported with 1.1.4)
java -cp sikulixapi.jar:jython-standalone.jar org.python.util.jython -jar your script.jar

the mentioned jars can be found in the SikuliX environment

... and another option is:
run this sikuli script from command line:
load(<path-to-your-script-jar>)
import __run__
