Cannot launch IDE 1.1.4 on MacOS 10.13.6: Java UnsupportedClassVersionError

Asked by CP on 2018-10-10

I downloaded current 1.1.4 sikulix.jar as well as jruby and jython from here:

I put all 3 in a new Sikuli folder in my home directory (I also tried Applications).

When I attempt to open sikulix.jar (via right-click open to bypass gatekeeper) jruby and jython files disappear, but otherwise nothing happens.

When I launch via terminal, `java -jar path` I get the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/sikuli/ide/Sikulix : Unsupported major.minor version 52.0

MacOS 10.13.6. According to the Java Control Panel I have current 8 update 181.

What do I need to do to resolve this?
