I am trying to set up my development environment to contribute to Elasticsearch. I have forked the repo, cloned it to my machine, and have run the 'idea' target with gradle. When I run './gradlew clean build' I see this message:

* Where:
Build file 'C:\Users\alici\IdeaProjects\elasticsearch\benchmarks\build.gradle' line: 31

I have set the JAVA9_HOME to where Java 10 is installed intentionally to see if I could get around this error but it will still ask for Java 9. My problem is that I'm unable to download Java 9 from Oracle without creating an account with them. Can someone recommend the version of JDK 9 that they are using for this project or a way to use only Java 10 instead of additionally installing Java 9?
Thanks!
