Circle CI 2.0 Android assembleDebug always failed

Question

Every time the Circle CI run ./gradlew assembleDebug part, it always fail. I don't know where's the problem but I've tried many ways like I ran it with and without daemon or setting up the gradle.properties. I've been searching for the answers on google and SO but still can't find the right one. Here is the error

Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed)

Here's my config.yml

It always failed on step *build_apk

Really appreciate any comments / answer, has been working on it since 2 days ago.

Answer 1

Difficult to say what fails without access to your CircleCI build machine (to check logs etc) but here's the config of CiclreCI v2 that build APK and deliver it to Fabric beta, also similar works to delivery APK to google play alpha/beta/prod channels.

I use this build as a template and it works on several projects for both Debug and Release builds with proguard or not.
