If you see this, you're all set!

NOTE: You will likely see jGRASP warnings pop up saying that jGRASP has not been tested with this Java Version or that this version is from an unsupported vendor:

These warnings happen because latest stable version of jGRASP has not yet been tested with the latest Adoptium JDK release. You can dismiss these pop up windows, and everything should still work fine.

If you get the following error:

Linux

Extract the .zip file you just downloaded to some permanent location. ~/jgrasp, ~/opt/jgrasp, or /usr/local/jgrasp would all be reasonable locations, but anything will do. cd into that directory and run java -jar jgrasp.jar. If all goes well, you should see this:
