I passed various flags such as --debug with no help. "Failed to create
Jar file" is an especially crappy error message.
Finally, found the right one: --stacktrace (why isn't this the default?!):

So it looks like gradle has java 18 compatibility issues? Can we
document a workaround or document "don't use this version, download 17
for now" ?
