App engine flexible Jetty/Resteasy version

[Mohammed Alhammouri]

I was running app engine flexible with jetty9 custom runtime , google cloud endpoints also
The app worked I have made a few changes and re deployed the app after couples a days.

The app now returns an error every time I make an API request: no such method Javax/ws/rs/core/MultivaluedMap

Strange thing the app works extermely fine when I run it local using gradle appRun
But when I upload it I get the error stated above. upload the app using gradle appengineDeploy

So it works locally crashes when I deploy any suggestions how to fix this, I have seen that this error is caused by multiple versions

of the same library but there is only one version for it when I looked at dependency hierarchy.

My latest gradle file is :
