Android Studio 在命令行编译工程

在Android sdk 目录下的samples/android-21/ 文件夹下，任找一个工程，如果在命令行直接编译

可能会报这种错误：

1	gradle buile.gradle

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14

FAILURE: Build failed with an exception.      * What went wrong:  Task 'build.gradle' not 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' not 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)

如果是这样，首先回到工程目录下，运行

 

1 2	./gradlew  ./gradlew  build

 

然后再执行进行编译

1 2 3

gradle build gradle tasks //查看android gradle的所有任务  gradle compileReleaseSource  //生成debug apk ，在build/outpus/apk 文件夹下
