Compile using Jack.
This allows to compile dex targeted java sources using Jack and Jill.
Default is still to compile with the legacy toolchain. Default can be
switched to the new toolchain by setting environement variable:
export ANDROID_COMPILE_WITH_JACK=true
Toolchain can also be forced for one module by defining
LOCAL_USE_JACK:=true # false
in the mk portion defining the module.
Jack execution environement can be controlled with:
Global variable ANDROID_JACK_VM allow to change the jvm executing Jack.
Global variable ANDROID_JACK_VM_ARGS allows to change default args given
to the jvm.
Global variable ANDROID_JACK_EXTRA_ARGS allows to define some default args
to give to Jack
LOCAL_JACK_VM_ARGS allows to override default args given to the jvm for
the module.
LOCAL_JACK_EXTRA_ARGS allows to override default args passed to Jack.
