Dependency issue with Eclipse Milo: NoSuchMethodError with OpcUaXmlDecoder.readVariantValue()

[Mame-Ibra859]

Hello,
I am trying to compile my project with Eclipse Milo, but I am encountering a Maven error during the command.

/media/sda9/mif/eclipse-milo/opc-ua-demo-server # docker run --rm -it -p 4840:4840 -v /tmp/opc-ua-demo-server-data:/app/data opc-ua-demo-server

Ha, when I renamed that and pushed it earlier this morning I had a feeling it was going to break something. Hang on…

[kevinherron]

Ok, once this commit builds and the SNAPSHOT is published, it should just start working: digitalpetri/uanodeset@0d5b6d2

(after you re-build the demo server docker image)

@Mame-Ibra859 you should be able to re-build the image and run it now.
