# Just bump this if you want to force a clean build.

# **********************************************************************
|
|
# WHEN DOING SO
|
|
# 1. DELETE ANY "add-clean-step" ENTRIES THAT HAVE PILED UP IN THIS FILE.
|
|
# 2. REMOVE ALL FILES NAMED CleanSpec.mk.
|
|
# 3. BUMP THE VERSION.
|
|
# IDEALLY, THOSE STEPS SHOULD BE DONE ATOMICALLY.

# ***********************************************************************
|
|
# Do not touch INTERNAL_CLEAN_BUILD_VERSION if you've added a clean step!
|
|
# ***********************************************************************
|
|
|
|
# If you don't need to do a full clean build but would like to touch
|
|
# a file or delete some intermediate files, add a clean step to the end
|
|
# of the list. These steps will only be run once, if they haven't been
|
|
# run before.
|
|
#
|
|
# E.g.:
|
|
# $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
|
|
# $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
|
|
#
|
|
# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
|
|
# files that are missing or have been moved.
|
|
#
|
|
# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
|
|
# Use $(OUT_DIR) to refer to the "out" directory.
|
|
#
|
|
# If you need to re-do something that's already mentioned, just copy
|
|
# the command and add it to the bottom of the list. E.g., if a change
|
|
# that you made last week required touching a file and a change you
|
|
# made today requires touching the same file, just copy the old
|
|
# touch step and add it to the end of the list.
|
|
#
|
|
# ************************************************
|
|
# NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST
|
|
# ************************************************
|
|
|
|
# For example:
|
|
#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates)
|
|
#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates)
|
|
#$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -print0 | xargs -0 rm -f)

#$(call add-clean-step, rm -rf $(PRODUCT_OUT)/data/*)
