16# Just bump this if you want to force a clean build.
17# **********************************************************************
18# WHEN DOING SO
19# 1. DELETE ANY "add-clean-step" ENTRIES THAT HAVE PILED UP IN THIS FILE.
20# 2. REMOVE ALL FILES NAMED CleanSpec.mk.
21# 3. BUMP THE VERSION.
22# IDEALLY, THOSE STEPS SHOULD BE DONE ATOMICALLY.

25INTERNAL_CLEAN_BUILD_VERSION := 6

27# ***********************************************************************
28# Do not touch INTERNAL_CLEAN_BUILD_VERSION if you've added a clean step!
29# ***********************************************************************

31# If you don't need to do a full clean build but would like to touch
32# a file or delete some intermediate files, add a clean step to the end
33# of the list.  These steps will only be run once, if they haven't been
34# run before.
35#
36# E.g.:
37#     $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
38#     $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)
39#
40# Always use "touch -c" and "rm -f" or "rm -rf" to gracefully deal with
41# files that are missing or have been moved.
42#
43# Use $(PRODUCT_OUT) to get to the "out/target/product/blah/" directory.
44# Use $(OUT_DIR) to refer to the "out" directory.
45#
46# If you need to re-do something that's already mentioned, just copy
47# the command and add it to the bottom of the list.  E.g., if a change
48# that you made last week required touching a file and a change you
49# made today requires touching the same file, just copy the old
50# touch step and add it to the end of the list.
51#
52# ************************************************
53# NEWER CLEAN STEPS MUST BE AT THE END OF THE LIST
54# ************************************************

56# For example:
57#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/APPS/AndroidTests_intermediates)
58#$(call add-clean-step, rm -rf $(OUT_DIR)/target/common/obj/JAVA_LIBRARIES/core_intermediates)
59#$(call add-clean-step, find $(OUT_DIR) -type f -name "IGTalkSession*" -print0 | xargs -0 rm -f)
60#$(call add-clean-step, rm -rf $(PRODUCT_OUT)/data/*)
