I ran a gradle build today to try and get an API to run locally and gradle is showing this message:
WARNING: Illegal reflective access by com.google.appengine.tools.development.StreamHandlerFactory (file:/C:/Users/{USER}/AppData/Local/google/ct4j-cloud-sdk/LATEST/google-cloud-sdk/platform/google_appengine/goo
gle/appengine/tools/java/lib/impl/appengine-local-runtime.jar) to method java.net.URL.getURLStreamHandler(java.lang.String)
WARNING: Please consider reporting this to the maintainers of com.google.appengine.tools.development.StreamHandlerFactory
I do not think this is causing an issue with the code running, but I do have an issue somewhere. I figured I would do what gradle suggested and report this to the maintainers.
