Is it possible build image from Android things's source code

Question

My company develop some app on Android things past years. I know Google alread had give up the project. But my boss want to try if it possilbe to build the image from the source code, make our product lives more years.

Search on google, it seems have Android things's repo on https://android.googlesource.com/platform/manifest/+/refs/heads/android-o-mr1-iot-release-1.0.14

I try

repo init

, and

repo sync

it success, good.

but after I type

lunch

I get some error like

pt@pt-VirtualBox:~/IOT_1.0.14$ lunch

I git clone the missing direct protobuf via

git clone https://android.googlesource.com/platform/external/golang-protobuf/

I try lunch again, and get the error

I read some tutorial about go language. But I have no idea how to fix it. It seems like a path problem.

thx, if any one can help.
