To utilize this repo and use the make scripts they run as follows:
. vendor/b00sted/tools/make-"device_name".sh "repo sync y/n" "make clean y/n" "-j#" "build type"
SO for a repo sync, and a nightly built after a make clean for the shadow with -j6 it would be the following command:
. vendor/b00sted/tools/make-shadow.sh y y 6 b
Please note that there is also a generic make script available for cm builds in general.
As you can see by the input required: REPO=$1 CLEAN=$2 LUNCH=$3 TYPE=$4 CORE=$5
That a y/n is required for repo, a y/n is required for clean, lunch combo is required, the build type, and the core to build at is also required. So for a repo sync, make clean, and a shadow build with userdebug at -j6 would be:
. /path/to/your/make_script.sh y y shadow userdebug 6
