If anyone else is looking for help here, my main issue updating a setup similar to that sample to gradle 5.3.1, gradle-node-plugin 1.3.1, and kotlin 1.3.30 was that the build was looking for

package.json

and

package-lock.json

files in the

build

directory (next to

node_modules

) when it was running my tests. My first pass fix was to copy files with just the body

{}

into that directly as part of the

prepareNodePackage

task from the sample. That works but generates a couple of warnings, so another option is to take those files after a successful build and check them in. I suspect there might be a cleaner way to do all that, though, since there’s node configuration happening at the gradle level which I would think should be able to generate the necessary json.
