Hi Leo, Thank you for the bug report. Fortunately, this issue has already been resolved, and will be fixed in the upcoming release of NetLogo! Isaac B. On Tuesday, March 24, 2026 at 4:31:52 PM UTC-5 Leo Niehorster-Cook wrote:

Hi fellow NetLogo addicts, I've been using NetLogo on a high-performance computing cluster and have been unable to use the new NetLogo 7.0+ with my current setup. Specifically using netlogo-headless.sh it fails with: ClassNotFoundException: []

It seems like the headless script uses ABSOLUTE_CLASSPATH pointing to a single jar: lib/app/netlogo-7.0.3.jar Consulting an LLM during debugging, it said that "NetLogo 7 requires all jars in lib/app/" - unsure if this is accurate but if so could result in an empty / invalid classpath passed to Java.

Please let me know if I'm doing something wrong or if anyone else has been able to run NetLogo 7 in headless mode. Cheers, Leo
