Android Studio compiles the project at the command line

Under the samples/android-21/folder in the Android SDK directory, either find a project if you compile directly on the command line

This error may be reported:

Gradle Buile.gradle

Failure:build failed with an exception.    * What went wrong:  Task ' Build.gradle ' isn't found in root project ' Borderlessbuttons '.    * Try:  Run gradle tasks to get a list of available tasks. Run with--info or--debug option to get more log output.    * Exception is:  org.gradle.execution.TaskSelectionException:Task ' Build.gradle ' isn't found in root project ' Borderlessbuttons '.      At Org.gradle.execution.TaskSelector.getSelection (taskselector.java:101) at      Org.gradle.execution.TaskSelector.getSelection (taskselector.java:76) at      Org.gradle.execution.commandline.CommandLineTaskParser.parseTasks (commandlinetaskparser.java:42) at      Org.gradle.execution.TaskNameResolvingBuildConfigurationAction.configure ( TASKNAMERESOLVINGBUILDCONFIGURATIONACTION.JAVA:44)  

If this is the case, first go back to the project directory and run

./gradlew  ./gradlew  Build

and then perform the compilation

Gradle Build Gradle Tasks//View all Tasks for Android Gradle Gradle Compilereleasesource  //Generate Debug APK, under Build/outpus/apk folder
