First and foremost I'm kinda new, so I might be missing something very basic.
I'm trying to compile elasticsearch from source from master branch (060b3aadd60116e6055e3fc35f472687719b7658). I've installed openjdk15 on a new fedora server and tried to run ./gradlew localDistro as specified on github. Here is the result:
```auto
[kazimazi@localhost elasticsearch]$ ./gradlew localDistro

What I installed wrongly was JRE and not JDK.
