Hello Kevin,
I just found what you said in Ignition Maven Plugin v1.0.11 Fails - #3 by xasga and yes but I suspect I didn’t do it properly because my gateway isn’t in developer mode. This is what I added to (the 3rd line) .conf, I assumed it must follow the same pattern.
# Application parameters. Add parameters as needed starting from 1
wrapper.app.parameter.1=com.inductiveautomation.catapult.Catapult
wrapper.app.parameter.2=Dia.developer.moduleupload=true
[edit] Dang it, I need to read more carefully…I didn’t set the parameter as Kevin said.
