# Build kzip files (source files for the indexing pipeline) for the given configuration,
# merge them and place the resulting all.kzip into $DIST_DIR.
# It is assumed that the current directory is the top of the source tree.
# The following environment variables affect the result:
# BUILD_NUMBER build number, used to generate unique ID (will use UUID if not set)
# DIST_DIR where the resulting all.kzip will be placed
# OUT_DIR output directory (out if not specified})
# TARGET_BUILD_VARIANT variant, e.g., `userdebug`
# TARGET_PRODUCT target device name, e.g., 'aosp_blueline'
# XREF_CORPUS source code repository URI, e.g., 'android.googlesource.com/platform/superproject'
: ${BUILD_NUMBER:=$(uuidgen)}
# The extraction might fail for some source files, so run with -k and then check that
# sufficiently many files were generated.
