6.4 build failed

[Hyojoung_Shin (HJ Shin)]

Hi,

I tried to build 6.4 but it failed.
I googled it for long time

If my step has errors, please correct me.

amazon linux, java "1.8.0_171"

$git clone -b 6.x https://github.com/elastic/elasticsearch.git
$cd elasticsearch
$./gradlew assemble --info

$ ./gradlew assemble --info
