Can't build Yarg from source using Oracle SE JDK 13 and OpenJDK 13

[Durobot]

Environment

• YARG version: Git Master branch, current as of October 7th, 2019
• JDK version: OpenJDK 13 (on Linux / Kubuntu 19.04, Windows 8.1), Oracle Java SE Development Kit 13 (on Windows 8.1)
• Operating system: Windows 8.1, Linux Kubuntu 19.04

Description of the bug

• Minimal reproducible example:

1. Remove JDK from the system (if installed), install Oracle SE JDK 13 or OpenJDK 13
2. Clone yarg from https://github.com/cuba-platform/yarg
3. Go to yarg/core
4. Run gradle.bat assemble (on Linux, ./gradle assemble)

• Expected behavior: Yarg should be built from source

• Actual behavior: Gradle fails with the following message:

  
  FAILURE: Build failed with an exception.

• What went wrong: Could not create service of type ScriptPluginFactory using BuildScopeServices.createScriptPluginFactory().

  Could not create service of type PluginResolutionStrategyInternal using BuildScopeServices.createPluginResolutionStrategy().

  
  Output of `gradlew.bat assemble --stacktrace` / `./gradlew assemble --stacktrace` on Windows 8.1 / Oracle SE JDK 13 and Linux / Kubuntu 19.04 OpenJDK 13 is attached.

Gradle doesn't work with Java 13. Keep it open until Gradle 6 is released. https://github.com/gradle/gradle/issues/8681 https://github.com/jhipster/generator-jhipster/pull/10486

Use java 11 for building from sources.

Thank you! May I suggest adding a note about this to https://github.com/cuba-platform/yarg/wiki > How to build it from sources?
