Question

I have imported the module in my project and its correctly imported. But i am getting this error. i have imported the Scanner control app module (By zebra). I have searched for many alternated solutions, but it's not working out.

Error:(36, 0) Could not get unknown property 'applicationVariants' for BuildType_Decorated{name=release, debuggable=false, testCoverageEnabled=false, jniDebuggable=false, pseudoLocalesEnabled=false, renderscriptDebuggable=false, renderscriptOptimLevel=3, minifyEnabled=false, zipAlignEnabled=true, signingConfig=null, embedMicroApp=true, mBuildConfigFields={}, mResValues={}, mProguardFiles=[/home/custom/AndroidStudioProjects/fireball5/fireball/build/intermediates/proguard-files/proguard-android.txt-2.3.3, /home/custom/AndroidStudioProjects/fireball5/fireball/scannercontrol/proguard-rules.pro], mConsumerProguardFiles=[], mManifestPlaceholders={}} of type com.android.build.gradle.internal.dsl.BuildType. <a href="openFile:/home/custom/AndroidStudioProjects/fireball5/fireball/scannercontrol/build.gradle">Open File</a>     apply plugin: 'com.android.library'  android {     compileSdkVersion 25     buildToolsVersion '25.0.0'      defaultConfig {         applicationId "com.zebra.scannercontrol.app"         minSdkVersion 19         targetSdkVersion 22         versionCode 71         versionName "2.0.8.0"         if (project.hasProperty('ADD_BUILD_TO_VERSION')) {             versionName = versionName.substring(0,versionName.lastIndexOf(".") + 1) + (System.getenv("BUILD_NUMBER") ?: "0")         }     }      signingConfigs {         release {             storeFile file("../../../keys/AndroidScannerSDK.keystore")             if (project.hasProperty('RELEASE_STORE_PASSWORD')) {                 storePassword RELEASE_STORE_PASSWORD                 keyAlias RELEASE_KEY_ALIAS                 keyPassword RELEASE_KEY_PASSWORD             }         }     }      buildTypes {         release {             minifyEnabled false             if (project.hasProperty('RELEASE_STORE_PASSWORD')) {                 signingConfig signingConfigs.release             }             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'             applicationVariants.all { variant ->                 appendVersionName(variant, defaultConfig)             }         }     }      lintOptions {         // Don't abort if Lint finds an error, otherwise the Jenkins build         // will be marked as failed, and Jenkins won't analyse the Lint output         abortOnError false     } } def appendVersionName(variant, defaultConfig) {     variant.outputs.each { output ->         if (output.zipAlign) {             def file = output.outputFile             def fileName = file.name.replace("scannercontrol-release.apk", "scanner_control_app_v" + defaultConfig.versionName  + ".apk")             output.outputFile = new File(file.parent, fileName)         }          def file = output.packageApplication.outputFile         def fileName = file.name.replace("scannercontrol-release", "scanner_control_app_v" + defaultConfig.versionName + ".apk")         output.packageApplication.outputFile = new File(file.parent, fileName)     } }  dependencies {     compile fileTree(include: ['*.jar'], dir: 'libs')     compile 'com.android.support:appcompat-v7:25.0.0'     compile 'com.android.support:design:25.0.0'     compile project(':BarcodeScannerLibrary') } enter code here 

Answer 1

You have an error at applicationVariants.all.

buildTypes {     release {         applicationVariants.all { variant ->             appendVersionName(variant, defaultConfig)         }     } } 

Fix 1:

This will not work since you are applying apply plugin: 'com.android.library'.

You have to change it to apply plugin: 'com.android.application' to use applicationVariants.all.

Fix 2:

If you want to keep using apply plugin: 'com.android.library'.

Change applicationVariants.all to libraryVariants.all or testVariants.all.

Explanation:

applicationVariants (only for the app plugin)

libraryVariants (only for the library plugin)

testVariants (for both plugins)

All three return a DomainObjectCollection of ApplicationVariant, LibraryVariant, and TestVariant objects respectively.

Hope this helps.

Edit:

apply plugin: 'com.android.library'  android {     compileSdkVersion 25     buildToolsVersion '25.0.3'      defaultConfig {         minSdkVersion 19         targetSdkVersion 22         versionCode 71         versionName "2.0.8.0"         if (project.hasProperty('ADD_BUILD_TO_VERSION')) {             versionName = versionName.substring(0,versionName.lastIndexOf(".") + 1) + (System.getenv("BUILD_NUMBER") ?: "0")         }     }      signingConfigs {         release {             storeFile file("../../../keys/AndroidScannerSDK.keystore")             if (project.hasProperty('RELEASE_STORE_PASSWORD')) {                 storePassword RELEASE_STORE_PASSWORD                 keyAlias RELEASE_KEY_ALIAS                 keyPassword RELEASE_KEY_PASSWORD             }         }     }      buildTypes {         release {             minifyEnabled false             if (project.hasProperty('RELEASE_STORE_PASSWORD')) {                 signingConfig signingConfigs.release             }             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     }      lintOptions {         abortOnError false     } }  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 project(':BarcodeScannerLibrary') }
