Task 'install' is ambiguous in root project 'TestApp'. Candidates are: 'installDebug', 'installDebugAndroidTest'

Question

I am working on one library project in android. I want to upload my library to the JCenter. I have created bintray account etc & followed all steps which are mentioned here http://inthecheesefactory.com/blog/how-to-upload-library-to-jcenter-maven-central-as-dependency/en

I did below changes in my application module & library module.

Application Module build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"


    defaultConfig {
        applicationId "com.app.testapp"
        minSdkVersion 8
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
    }


}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile project(':testlib')
}

Library Module build.gradle

apply plugin: 'com.android.library'

ext {
    bintrayRepo = 'maven'
    bintrayName = 'test-sdk'

    publishedGroupId = 'in.test.sdk'
    libraryName = 'testlib'
    artifact = 'test-sdk'

    libraryDescription = 'A wrapper for Facebook Native Like Button (LikeView) on Android'

    siteUrl = 'https://github.com/xyz/testsdk'
    gitUrl = 'https://github.com/xyz/testsdk.git'

    libraryVersion = '1.0.0'

    developerId = 'xyz'
    developerName = 'xyz'
    developerEmail = '[email protected]'

    licenseName = 'The Apache Software License, Version 2.0'
    licenseUrl = 'http://www.apache.org/licenses/LICENSE-2.0.txt'
    allLicenses = ["Apache-2.0"]
}

version = "1.0.0"
android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
    }

    buildTypes {
        release {
            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
           // proguardFiles 'proguard-project.txt'
        }
        packagingOptions {
            exclude 'META-INF/LICENSE.txt'
        }
    }


}

dependencies {
    compile 'com.android.support:support-v4:22.2.0'
    compile files('libs/gson-2.3.1.jar')
    compile files('libs/android-query-full.0.26.8.jar')
    compile files('libs/httpmime-4.1.1.jar')
    compile files('libs/jackson-annotations-2.5.0.jar')
    compile files('libs/javax.annotation.jar')
    compile files('libs/libGoogleAnalyticsServices.jar')
    compile files('libs/okhttp-2.3.0.jar')
    compile files('libs/okio-1.3.0.jar')
    compile files('libs/retrofit-1.9.0.jar')
}

Project root build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.3'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
        classpath 'com.github.dcendents:android-maven-plugin:1.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }


}

allprojects {

    repositories {
        jcenter()
    }
}

When I am doing this gradlew install then I am getting this error

FAILURE: Build failed with an exception.

* What went wrong:          
Task 'install' is ambiguous in root project 'TestApp'. Candidates are: 'installDebug', 'installDebugAndroidTest'.

* Try:                      
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED                

Total time: 11.685 secs   

I spent three days on same but could not get proper solution of it. Please suggest how to resolve it.

Perhaps you forgot to add these lines to the end of your Library Module build.gradle:

apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/installv1.gradle'
apply from: 'https://raw.githubusercontent.com/nuuneoi/JCenter/master/bintrayv1.gradle'
