# The complexity of this makefile is not the fault of make, but the fault
# of javac and javah. The basic problems are:
#    1) Compiling a single Java source file unpredictably generates anything
#       between zero (0!) and an infinite number of .class files!
#    2) There is no hint, for which classes javah needs to be run,
#       and it happily generates .h files for classes with no native methods.
#    3) javac and javah do not cleanup anything, for example if an internal
#       class (potentially with native methods) is removed from a Java source file.
# This makefile is a tribute to GNU make. And yes, it was harder to write than it is
# to read. The include/excludes of directories and files are only a temporary measure
# to work around the messy jdk sources that put platform specific code in src/share/classes.
# We should move most of the functionality of this makefile into a
# smart javac/javah/javadoc/jar combo tool. sjavac ?
# I.e. 1) It always generates a single output, a zip-file from a number of source roots.
#         The zip file contains information that enable incremental builds with full 
#         dependency tracking between packages.
#      2) It automatically generates the right .h files.
#      3) It keeps its house clean.
#      *) Generates intermediate files to be used for javadoc generation later.
#      and does all the other useful things that this makefile does, such as:
#          use all cores for compilation, reuse the running JVM for all compilations,
#          and has pubapi dependency tracking to minimize the number of files
#          that need to be recompiled during an incremental build.
# A zip file, or several zip files combined, can then be converted to a .jar file, or to a .jmod file.
# This would make this makefile much much simpler. I.e. make can be used
# for its real purpose, track dependencies and trigger a recompile if a
# dependency has changed.
# When you read this source. Remember that $(sort ...) has the side effect
# of removing duplicates. It is actually this side effect that is
# desired whenever sort is used below!
