30 # Modularizing the JDK
31 # - Post jdk build process until the source tree is restructured
32 # for modules build
33 # - <outputdir>/modules/<module> will be created for each module.
34 #
35 # Steps:
36 # 0. During jdk build before this makefile is invoked, classes,
37 # resource files, and other non-class files such as native libraries,
38 # properties file, images, etc are created.
39 #
40 # Non-class files are copied to <outputdir>/tmp/modules/<MODULE>
41 # directory in this step to prepare for the post-build modularization.
42 #
43 # The MODULE variable defined in other makefiles specifies
44 # the lowest-level module that the non-class files belong to.
45 # The name might or might not be the same as the name of the modules
46 # in the resulting <outputdir>/modules directory.
47 #
48 # 1. Unpack all jars in the <builddir>/lib directory to a temporary
49 # location (<outputdir>/tmp/modules/classes) to prepare for modules
50 # creation.
51 #
52 # 2. Run ClassAnalyzer tool to analyze all jdk classes and generate
53 # class list for all modules and also perform dependency analysis.
54 #
55 # Input configuration files :-
56 #
57 # modules.config : defines the low-level modules and specifies
58 # what classes and resource files each module includes.
59 # modules.group : defines the module groups and its members.
60 # jdk7.depconfig : lists the dynamic dependencies including
61 # use of reflection Class.forName and JNI FindClass and
62 # service provider.
63 # optional.depconfig : lists the optional dependencies
64 #
65 # 3. Create one directory for each module (<outputdir>/modules/<module>)
66 # based on the output files from (2).
67 #
68 # modules.list lists the modules to be created for the modules
69 # build and its members. For each module (m) in modules.list,
70 # a. create $m/lib/$m.jar with all classes and resource files
71 # listed in $m.classlist and $m.resources respectively.
72 # b. copy all non-class files from its members to
73 # <outputdir>/modules/$m.
