What was the expected behaviour?

The test APK builds successfully.

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

• I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

# create 0.70.7 project / this also occurs on 0.71.3
npx [email protected] init Sample --version 0.70.7
cd Sample

# add detox
npm i detox

# follow step 4 of https://wix.github.io/Detox/docs/introduction/project-setup#step-4-additional-android-configuration

# build test apk
cd android
./gradlew assembleAndroidTest -DtestBuildType=debug

Then you will run into #3867, which you can workaround using this solution.

After applying the workaround build again and notice the error above.

In what environment did this happen?

Detox version: 20.5.0
React Native version: 0.70.7 / 0.71.3
Has Fabric (React Native's new rendering system) enabled: (yes/no) no

I am not familiar with the java ecosystem, I don't know if that helps.

[arcln]

I have seen #1367 which looks very similar however my test is properly placed at android/app/src/androidTest/java/com/sample/DetoxTest.java.

[arcln]

My bad this was caused by wrong placement of the maven repository source.

I had to put it in "allprojects" section as stated in the docs, not "buildscript" section.

Change :

buildscript {
    repositories {
        maven { url("$rootDir/../node_modules/detox/Detox-android") }
    }
}

To :

allprojects {
    repositories {
        maven { url("$rootDir/../node_modules/detox/Detox-android") }
    }
}

New react native projects don't have the allprojects section which makes this easy to be missed. I think the docs should make it more explicit on step 4.

// Full android/build.gradle from a fresh react-native init
// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "33.0.0"
        minSdkVersion = 21 // (1)
        compileSdkVersion = 33
        targetSdkVersion = 33
        kotlinVersion = '1.7.21' // (2)

        // We use NDK 23 which has both M1 support and is the side-by-side NDK version from AGP.
        ndkVersion = "23.1.7779620"
    }
    repositories {
        google()
        mavenCentral()

    }
    dependencies {
        classpath("com.android.tools.build:gradle:7.3.1")
        classpath("com.facebook.react:react-native-gradle-plugin")
        classpath("org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion") // (3)
    }
}

allprojects { // (4)
    repositories {
        maven {
          url("$rootDir/../node_modules/detox/Detox-android")
        }
    }
}

@carlosalmonte04 I totally agree the docs should be more clear. Struggled with this for longer than I care to admit! Gonna submit PR for the docs

edit: I believe the label can be changed to something other than bug/triage or closed, as it's user error. Though very easy to make if you're speeding through the docs like I was.

thanks I also missed this step.

[dids-reyes]

Thanks for this! the closing curly brace was collapsed on the docs that's why i missed it
