# This file makes modifications to module-info.java files based on the build
28
# configuration.
29
#
30
# Depending on build platform, imported modules and optional parts of the build
31
# being active, some modules need to have extra exports, provides or uses
32
# declarations added to them. 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.
