These optional extras are defined in .extra files: 33# 34# src/<module>/<share,platform>/classes/module-info.java.extra 35# 36# The contents of the .extra files are simply extra lines that could fit into 37# the module-info file. 38# 39# This makefile is called once for each from-module with the variable 40# MODULE naming the from-module. 41# 42# The modified module-info.java files are put in the gensrc directory where 43# they will automatically override the static versions in the src tree. 44# 45################################################################################ 46 47default: all 48 49include $(SPEC) 50include MakeBase.gmk 51include Modules.gmk 52 53################################################################################ 54# Define this here since jdk/make/Tools.gmk cannot be included from the top 55# make directory.
