# 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. |
|
