27 # 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. |
|
44 # |
