Get Unexpected interactiveMode: when running app with Gradle.

[mitchelldehaven]

I was using the maven build previously and switched to the Gradle build. First time running appRun resulted in the following output:
> Task :appRun Unexpected interactiveMode:
I think the culprit is interactiveMode = '' in build.gradle, as removing that line allows it to launch successfully.

Thank you @mitchelldehaven !
Normally this message has no consequence, everything works fine.
If we remove this line interactiveMode = '', we have gradle running in interactive mode and this message:

Press any key to stop the server.

and indeed when we press any keys, the server stops, which I find particularly unpleasant... so I neutralize the interactive mode with the interactiveMode = '' line. However then I didn't find a way to avoid having the

Task :appRun Unexpected interactiveMode:

in the console. But as it has no consequence, it's not really a concern I think.

Ah, perhaps I was mistaken. I thought when this message showed I could not access the web interface. Thanks!
