Looks like this was caused by an automatic Java update on the server, and it kept on breaking subsequent builds because they were reusing the same Gradle daemon instance. The daemon does have a timeout, but it defaults to 3 hours, and the builds were happening more frequently than that.
I've restarted the daemon, and I've disabled future automatic updates of Java with this command:
To install any future updates:
apt-mark holdcommand above.
