Estoy tratando de construir proyectos de Android en la línea de comandos OSX (Mavericks 10.9.5) usando este procedimiento:http://developer.android.com/tools/building/building-cmdline.html.

Este tutorial explica el uso de assembleDebug / assembleRelease para construir un proyecto de Android.

Lamentablemente gradle no crea elassembleDebug oassembleRelease objetivos.

Ejecutando./gradlew assembleDebug devuelve esto:

FAILURE: Build failed with an exception.

* What went wrong:
Task 'assembleDebug' not found in root project 'test'.

* 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
