React Native v.0.42.3 - AssembleRelease dosen't generate apk file.

[agerro]

Description

I was trying to generate a release apk of my react native application, with the "cd android && gradlew assembleRelease". In the terminal, it shows success, but there is no apk file in the folder suggested by React Native ("/outputs/apk...").

I've followed the guide https://facebook.github.io/react-native/docs/signed-apk-android.html with no luck.

Reproduction Steps and Sample Code

1. cd myProject
2. cd android
3. gradlew assembleRelease

Output:
C:\Users\makar4\Documents\BitBucket\sf\android>gradlew assembleRelease
Incremental java compilation is an incubating feature.

@agerro, i have the same problem. How did you fix it?

[jtl3d]

@agerro, I am having this issue as well. Please update with how you fixed it!

@victorpluna did you every figure it out??

[jtl3d]

@agerro @victorpluna Nevermind - one of my developers added the following which trolled me for a good while until I spotted it:

buildDir = "C:/tmp/${rootProject.name}/${project.name}"

[agerro]

@jtl3d Sorry, I must have missed answering you. Nice to hear that you figured it out. BEST WAY TO LEARN ;)
I cant remember how we solved it, I got on another assignment before I could see how we solved it. So in a way, you helped me :)

Solution of my case:
In the file 'settings.gradle', was missing the line:
include ':app'
