    12  source build/envsetup.sh    # Add "lunch" (and other utilities and variables)
    13                              # to the shell environment.
    14  lunch [<product>-<variant>] # Choose the device to target.
    15  m -j [<goals>]              # Execute the configured build.
    16  
    17  Usage of "m" imitates usage of the program "make".
    18  See '"${SCRIPT_DIR}"'/Usage.txt for more info about build usage and concepts.

    20  Common goals are:
    21  
    22      clean                   (aka clobber) equivalent to rm -rf out/
    23      checkbuild              Build every module defined in the source tree
    24      droid                   Default target
    25      nothing                 Do not build anything, just parse and validate the build structure
    26  
    27      java                    Build all the java code in the source tree
    28      native                  Build all the native code in the source tree
    29  
    30      host                    Build all the host code (not to be run on a device) in the source tree
    31      target                  Build all the target code (to be run on the device) in the source tree
    32  
    33      (java|native)-(host|target)
    34      (host|target)-(java|native)
    35                              Build the intersection of the two given arguments
    36  
    37      snod                    Quickly rebuild the system image from built packages
    38                              Stands for "System, NO Dependencies"
    39      vnod                    Quickly rebuild the vendor image from built packages
    40                              Stands for "Vendor, NO Dependencies"
    41      pnod                    Quickly rebuild the product image from built packages
    42                              Stands for "Product, NO Dependencies"

    45  So, for example, you could run:
    46  
    47  cd '"${TOP}"'
    48  source build/envsetup.sh
    49  lunch aosp_arm-userdebug
    50  m -j java
    51  
    52  to build all of the java code for the userdebug variant of the aosp_arm device.
