no test task in gradle build

I am trying to build and imported Android project in Android Studio/Eclipse.
My goal is to write automated test to the current project. First, I am trying to build the project and then to make an apk file of it so I will be able to execute real device/emulator tests on it.
Here are my available Gradle tasks
There is no build or test or assemble and etc. tasks which are I am looking to use so I will reach my goal.
Here is my project tree and both build.gradle files
`
apply plugin: "java"
repositories {
jcenter()
}
dependencies {
compile 'org.slf4j:slf4j-api:1.7.13
testCompile 'junit:junit:4.12'
}
and
apply plugin: 'com.android.application'
version = "1.2"
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
}
}
android {
compileSdkVersion 25
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "sdk.mobfox.com.appcore"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
multiDexEnabled true
archivesBaseName = "MobFox-Android-SDK-Client-" + version + ".apk"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dexOptions {
javaMaxHeapSize = "4g"
}
lintOptions {
abortOnError false
}
}
repositories {
jcenter()
mavenCentral()
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.google.android.gms:play-services-ads:11.0.0'
compile 'com.android.support:multidex:1.0.1'
compile 'com.danikula:videocache:2.7.0'
testCompile 'junit:junit:4.12'}
I tried to open the project in Android Studio but got the same state.
I opened a new Gradle project in Eclipse and saw that the tasks I am looking for are available there - I believe because of the 'java-library' plugin which added to the build.gradle root file but I use the same plugin in my root build file and did not receive what I expected.
I was succeeded to execute the Gradle "tasks" which gave me the next response in console :

**1. What is the reason I cannot get all the task I got when I open a new project?
How can I add these tasks so I will be able to create apk file, build and execute integration tests?**

task, you write in project level build.gradle file. See below pic for the reference.
You are posting module level build.grale file.

Applying com.android.application should be enough, you should not apply java plugin on the root either and add dependencies there.
Operate on your app project, with Java specific stuff.

How to run ./gradlew test

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

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.
https://github.com/leandroBorgesFerreira/mvp-kotlin-example/pull/1
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'

Build Failed when i try to run the app

I have the error like
"Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/zzpm$zza$zza.class"
What should i do to remove this error

compile 'com.google.android.gms:play-services-gcm:8.4.0'
//compile files('libs/google-play-services.jar')
}

As #Vaiden says the issue was:
"It seems that you have at least one library already bundled with GMS"
Every time that you face a duplicate entry error run ./gradlew app:dependencies and make sure that there is no duplicated versions of a same module. For example: in my case I had:
compile 'com.google.android.gms:play-services-gcm:9.0.0'
When I tried to use firebase in my project I add it like:
compile 'com.google.firebase:firebase-core:9.+'
compile 'com.google.firebase:firebase-messaging:9.+'
That makes my app crash cause when I navigate to the: app > build > intermediates > exploded-aar > com.google.android.gms one of the folders (play-services-basement) pull a version 9.4.0 instead 9.0.0 so what I did was to unificate the versions by adding firebase like:
compile 'com.google.firebase:firebase-core:9.0.0'
compile 'com.google.firebase:firebase-messaging:9.0.0'
In theory you can solve this too by pushing the firebase to 9.4.0 instead.
The bottom line is to try to know which things are your dependencies introducing to the app and check "WHO" is introducing the same thing to the app, once you get there try to set a specific version of that duplicated dependency.

Based from this forum, try to change the gradle inside your C:\Program Files\Android\Android Studio\gradle\ to gradle-2.10. Also, it seems unlikely that a program that is designed to run on an Android device doesn't need all of the jars. Try removing some of them.
Check this related SO questions:
TransformException duplicate entry for common.annotations.Beta
Android dependency issue with gms play services

It seems that you have at least one library already bundled with GMS.
None of the dependencies stated in your gradle build file should have it, so the culprit might be a library jar file in your libs dir. So either you have something in your libs dir you shouldn't have put there, or a library that has GMS bundled inside of it.
Did you remember to delete libs/google-play-services.jar?

google play service error

I got this below error
Error:(1, 1) A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
> Gradle version 2.10 is required. Current version is 2.8. If using the gradle wrapper, try editing the distributionUrl in C:\Users\TARUN\Desktop\GingerBuds\gradle\wrapper\gradle-wrapper.properties to gradle-2.10-all.zip
Then I changed the above gradle path, Then following problem occurred,
I am getting this exception, while building my project . I rebuild and clean the project and updated google-play-services , then also i got error. can anyone please help me how to solve this.

2.0.0-alpha6 (2016/1/15)
Instant Run
Fix alpha5 reported issues :
- cannot build when importing play-services.
You should update android gradle tools version
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha6'
}

This exception is thrown during a failed attempt to open the file denoted by a specified Path-name.
You can use
compile 'com.google.android.gms:play-services:8.3.0'
Update your classpath
classpath 'com.android.tools.build:gradle:2.0.0-alpha2'

this will solve it
dependencies {
classpath 'com.android.tools.build:gradle:1.5.0'
classpath 'com.google.gms:google-services:2.0.0-alpha2'
}
and
compile 'com.google.android.gms:play-services:8.3.0'

update gradle version to alpha9 in project level gradle file
classpath 'com.android.tools.build:gradle:2.0.0-alpha9'

i tried to import admob ads to a new app i was making and i ran into this problem...... i found the solution the be the StartAppInApp file being located in the wrong spot or not being there..... my app needed the StartAppInApp-3.1.1.jar file to be located in the libs folder and when i looked at my app there was no libs folder located there at all .....
open your main app folder... then click app and you should have 3 folders.... src ... build.... and libs .....
in my case there was no libs folder..... so i created the libs folder and then went and copied the StartAppInApp-3.1.1.jar file from a different android project i had and i pasted it to the new libs folder i made in my current project... the error is now GONE!
i also made sure to include
compile files('libs/StartAppInApp-3.1.1.jar')
in the dependencies of my app gradle file
not sure if this is a solid answer but if anyone has this problem double check your StartAppInApp-3.1.1.jar location and version and check your gradle dependencies

Error:Configuration with name 'default' not found when trying to import project as library into Android Studio

I checked all the other threads about this topic but couldn't find an answer.
I am trying to import the Twoway View Project as a library into Android Studio.
Both projects run fine on their own but I always get the same Gradle Error: Error:Configuration with name 'default' not found when trying to import.
I have the project copied into a "libraries" directory in the root folder of my project and the following gradle structure:
settings.gradle of my project:
include ':libraries:twoway-view-master',':app'
build.gradle of "app":
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "app.com.jeldrik.teacherslittlehelper"
minSdkVersion 13
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(':libraries:twoway-view-master')
and in twoway-view-master build.gradle:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0'
}
}

That twowayview-master build.gradle file isn't a buildscript for a standalone module; it lacks any sort of apply plugin statement that would tell Gradle how it should compile something. This looks like the top-level build file of a multimodule-structured project. In your settings.gradle file, you should point at the module in the project you're trying to include, not the build file at the top level.

Did you try it out using File -> New Module?
Or try setting the dependencies from here as well : File -> Project Structure -> Dependencies

I have recently got into same issue. As Scott said we have to include individual modules in our project's build.gradle file. This TwoWayView library has 3 different modules
core
layouts
sample
Say if you want to add core and layouts, add the below lines in your project's build.gradle file (Assuming you have twoway-view-master folder inside libraries folder which is inside your app folder).
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile project(':your-app-folder:libraries:twoway-view-master:core')
compile project(':your-app-folder:libraries:twoway-view-master:layouts')
}
Then add the same path to your project's settings.gradle file
include ':your-app-folder:libraries:twoway-view-master:core'
include ':your-app-folder:libraries:twoway-view-master:layouts'
NOTE: The build.gradle files inside core and layouts have wrong path to gradle-mvn-push.gradle file. So change the path from
apply from: "${rootDir}/gradle/scripts/gradle-mvn-push.gradle"
to
apply from: "${rootDir}/your-app-folder/libraries/twoway-view-master/gradle/scripts/gradle-mvn-push.gradle"
If you still get error in layouts' build.gradle file, change this line
compile project(':core')
to
compile project(':your-app-folder:libraries:twoway-view-master:core')
Do the same change if you're also using sample's build.gradle file in your project.
