Matthew Woehlke b41771dfeb UseJava.cmake: document add_jar compat shim 
Document the logic that parses for backward compatibility the old
variables that were used to control add_jar prior to named argument
support. In particular, document that the reason this logic exists is
for backward compatibility, and that new features do not need to add to
it.

Raw Blame History

# - Use Module for Java
# This file provides functions for Java. It is assumed that FindJava.cmake
# has already been loaded. See FindJava.cmake for information on how to
# load Java into your CMake project.
#
# add_jar(target_name
# [SOURCES] source1 [source2 ...] [resource1 ...]
# [INCLUDE_JARS jar1 [jar2 ...]]
# [ENTRY_POINT entry]
# [VERSION version]
# [OUTPUT_NAME name]
# [OUTPUT_DIR dir]
# )
#
# This command creates a <target_name>.jar. It compiles the given source files
# (source) and adds the given resource files (resource) to the jar file. If
# only resource files are given then just a jar file is created. The list of
# include jars are added to the classpath when compiling the java sources and
# also to the dependencies of the target. INCLUDE_JARS also accepts other
# target names created by add_jar. For backwards compatibility, jar files
# listed as sources are ignored (as they have been since the first version of
# this module).
#
# The default OUTPUT_DIR can also be changed by setting the variable
# CMAKE_JAVA_TARGET_OUTPUT_DIR.
#
# Additional instructions:
# To add compile flags to the target you can set these flags with
# the following variable:
#
# set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
#
# To add a path or a jar file to the class path you can do this
# with the CMAKE_JAVA_INCLUDE_PATH variable.
#
# set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
#
# To use a different output name for the target you can set it with:
#
# add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar)
#
# To use a different output directory than CMAKE_CURRENT_BINARY_DIR
# you can set it with:
#
# add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
#
# To define an entry point in your jar you can set it with the ENTRY_POINT
# named argument:
#
# add_jar(example ENTRY_POINT com/examples/MyProject/Main)
#
# To add a VERSION to the target output name you can set it using
# the VERSION named argument to add_jar. This will create a jar file with the
# name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
# pointing to the jar with the version information.
#
# add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
#
# If the target is a JNI library, utilize the following commands to
# create a JNI symbolic link:
#
# set(CMAKE_JNI_TARGET TRUE)
# add_jar(shibboleet shibbotleet.java VERSION 1.2.0)
# install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
# install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
#
# If a single target needs to produce more than one jar from its
# java source code, to prevent the accumulation of duplicate class
# files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
# to calling the add_jar() function:
#
# set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
# add_jar(foo foo.java)
#
# set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
# add_jar(bar bar.java)
#
# Target Properties:
# The add_jar() functions sets some target properties. You can get these
# properties with the
# get_property(TARGET <target_name> PROPERTY <propery_name>)
# command.
#
# INSTALL_FILES The files which should be installed. This is used by
# install_jar().
# JNI_SYMLINK The JNI symlink which should be installed.
# This is used by install_jni_symlink().
# JAR_FILE The location of the jar file so that you can include
# it.
# CLASS_DIR The directory where the class files can be found. For
# example to use them with javah.
#
# find_jar(<VAR>
# name | NAMES name1 [name2 ...]
# [PATHS path1 [path2 ... ENV var]]
# [VERSIONS version1 [version2]]
# [DOC "cache documentation string"]
# )
#
# This command is used to find a full path to the named jar. A cache
# entry named by <VAR> is created to stor the result of this command. If
# the full path to a jar is found the result is stored in the variable
# and the search will not repeated unless the variable is cleared. If
# nothing is found, the result will be <VAR>-NOTFOUND, and the search
# will be attempted again next time find_jar is invoked with the same
# variable.
# The name of the full path to a file that is searched for is specified
# by the names listed after NAMES argument. Additional search locations
# can be specified after the PATHS argument. If you require special a
# version of a jar file you can specify it with the VERSIONS argument.
# The argument after DOC will be used for the documentation string in
# the cache.
#
# install_jar(TARGET_NAME DESTINATION)
#
# This command installs the TARGET_NAME files to the given DESTINATION.
# It should be called in the same scope as add_jar() or it will fail.
#
# install_jni_symlink(TARGET_NAME DESTINATION)
#
# This command installs the TARGET_NAME JNI symlinks to the given
# DESTINATION. It should be called in the same scope as add_jar()
# or it will fail.
#
# create_javadoc(<VAR>
# PACKAGES pkg1 [pkg2 ...]
# [SOURCEPATH <sourcepath>]
# [CLASSPATH <classpath>]
# [INSTALLPATH <install path>]
# [DOCTITLE "the documentation title"]
# [WINDOWTITLE "the title of the document"]
# [AUTHOR TRUE|FALSE]
# [USE TRUE|FALSE]
# [VERSION TRUE|FALSE]
# )
#
# Create java documentation based on files or packages. For more
# details please read the javadoc manpage.
#
# There are two main signatures for create_javadoc. The first
# signature works with package names on a path with source files:
#
# Example:
# create_javadoc(my_example_doc
# PACKAGES com.exmaple.foo com.example.bar
# SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
# CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
# WINDOWTITLE "My example"
# DOCTITLE "<h1>My example</h1>"
# AUTHOR TRUE
# USE TRUE
# VERSION TRUE
# )
#
# The second signature for create_javadoc works on a given list of
# files.
#
# create_javadoc(<VAR>
# FILES file1 [file2 ...]
# [CLASSPATH <classpath>]
# [INSTALLPATH <install path>]
# [DOCTITLE "the documentation title"]
# [WINDOWTITLE "the title of the document"]
# [AUTHOR TRUE|FALSE]
# [USE TRUE|FALSE]
# [VERSION TRUE|FALSE]
# )
#
# Example:
# create_javadoc(my_example_doc
# FILES ${example_SRCS}
# CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
# WINDOWTITLE "My example"
# DOCTITLE "<h1>My example</h1>"
# AUTHOR TRUE
# USE TRUE
# VERSION TRUE
# )
#
# Both signatures share most of the options. These options are the
# same as what you can find in the javadoc manpage. Please look at
# the manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and
# VERSION.
#
# The documentation will be by default installed to
#
# ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
#
# if you don't set the INSTALLPATH.
