Edge.jar gives an error when building

Hello, I’m very new to OpenEMS.
I’ve tried to export an edge as a runnable jar, but when trying to build it from the command line, I get “no main manifest attribute, in edge.jar”.

any help?

Hi Ghada,

welcome to the OpenEMS Community. Does this happen, when you build using gradlew buildEdge? See this page in the documentation:


Also note, that there are prebuilt jar files now since latest release:


I tried using gradle but still get an error.
I will check out the new release, thank you!
