Getting Processing to export as a executable Jar - Processing Forum

Export sketch to jar

Is it possible to export a processing sketch as a jar, or to turn the exported files into an executable jar? I tried following the instructions here https://forum.processing.org/one/topic/getting-processing-to-export-as-a-executable-jar#25080000001605035.html, but when I tried to open the jar, it said the file was corrupt.
