lunch 吧？类似于choosecombo，选择编译编译参数的。执行source build/envsetup.sh才有。其实我也不是特别了解。我觉得应该是在envsetup.sh里定义的。不知道你用过choosecombo没有，跟那个是类似的。

$ source build/envsetup.sh

including device/asus/grouper/vendorsetup.sh

including device/generic/armv7-a-neon/vendorsetup.sh

including device/generic/armv7-a/vendorsetup.sh

including device/moto/wingray/vendorsetup.sh

including device/qcom/common/vendorsetup.sh

including device/samsung/crespo/vendorsetup.sh

including device/samsung/maguro/vendorsetup.sh

including device/ti/panda/vendorsetup.sh

including sdk/bash_completion/adb.bash

init spec is ct

$ lunch

Which would you like? [full-eng]

这个时候，你可以选择想要编译的选项。
