Kotlin support for server-side

[uny]

If a server-side gradle project, which means the project with com.google.cloud.tools.endpoints-framework-server gradle plugin, only has Kotlin source files, appengineRun will complain that

* What went wrong:
A problem was found with the configuration of task ':endpointsDiscoveryDocs'.
> Directory '/path/to/project/build/classes/java/main' specified for property 'classesDir' does not exist.

Creating a dummy Java class is a workaround.

Looks like you might be using an older version of the plugin? Can you confirm what version of endpoints-framework-server you are using?

I was careless.
I followed this tutorial, and used v1.0.2.
classpath 'com.google.cloud.tools:endpoints-framework-gradle-plugin:1.0.2'
Updating to v2.0.0 solves the problem.
Thank you for your help.
