How to build Android P SDK

[dazza5000]

I was trying to build with the following config:

#!/bin/bash
ARCH=arm64
LUNCH=rk3399_box-userdebug
UBOOT_DEFCONFIG=rk3399
KERNEL_DEFCONFIG=rockchip_defconfig
KERNEL_DTS=rk3399-rockpro64
JOBS=4


And I get the following exception:

Any ideas on what that would be?
