Hi nada,
Thanks for getting in touch. I am afraid I cannot help you in this case, because I have never seen this error myself.
Are you able to build the project manually from a terminal? See Build OpenEMS Edge :: Open Energy Management System
Following commands should work: (as per eric’s comment → Release 2024.2.0 · OpenEMS/openems - #4 by eric.bram)
./gradlew buildNeeded
./gradlew buildEdge
Regards,
Stefan
