How to run ./gradlew test

Question

I'm trying to test an app from the command line. When I run my test from the Android Studio, everything goes fine. But when I try to run the command:

./gradlew test

I get this error:

Task 'test' not found in root project 'mvp_kotlin_example'.

I don't have problems using ./gradlew build or ./gradlew clean. I just created a project to try the ./gradlew test and it worked.

In mvp_kotlin_example I am using Robolectric for tests and Kotlin for development.

So how can I make my tests work from the command line?

Edit:

This is a open source project, so all the code can be found in the

https://github.com/leandroBorgesFerreira/mvp-kotlin-example

This is my build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply from: '../jacoco.gradle'

android {
    compileSdkVersion 25

    defaultConfig {

        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            testCoverageEnabled = true
        }
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
}

    mavenCentral()

kapt {
    generateStubs = true
}

Edit 2:

This is what I see after running ./gradlew tasks (it's a lot less tasks than the usuall)

------------------------------------------------------------
All tasks runnable from root project

Here the problem has nothing to do with your build.gradle your project was missing the settings.gradle file that tells gradle to include the app folder as a module. I've created PR #1 on your project to resolve this defect, when merged you should be able to run ./gradlew clean test from the root project directory.

Solution is to just add a oneline settings.gradle file to the root project that declares the modules included in the build.

$ cat settings.gradle 
include 'app'
