Hi,

I just tried to reproduce this on the very same commit (i.e. `508c38a450a`) with the same configuration as you:

```auto
  Gradle Version : 5.4.1
  OS Info : Mac OS X 10.13.6 (x86_64)
  JDK Version : 12 (Oracle Corporation 12.0.1 [OpenJDK 64-Bit Server VM 12.0.1+12])
  JAVA_HOME : /Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home

```

The build went fine for me. Our [development setup docs](https://github.com/elastic/elasticsearch/blob/master/CONTRIBUTING.md#contributing-to-the-elasticsearch-codebase) mention to define also `JAVA8_HOME` ... `JAVA11_HOME` and I suspected that this is the cause so I've removed all related environment variables until I was left with this:

```auto
daniel@io:7/elasticsearch ‹508c38a450a›$ env | grep "JAVA.*HOME"
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home
RUNTIME_JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home
JAVA12_HOME=/Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home

```

Running either `./gradlew clean` or `./gradlew run` still works fine for me.

What's odd is this here in your output:

```auto
Build file '/Users/es/elasticsearch/libs/core/bin/build.gradle' line: 108

```

That file does not exist for me. So I wonder whether you have uncommitted changes or other leftovers in your checkout. You can check this with `git status`. You can tell git to remove untracked files from your working tree with `git clean -xdf`. WARNING(!): This will **delete** all uncommitted files so proceed with caution if you have uncomitted changes). Alternatively you can also try with a fresh checkout in a different directory.

Daniel
