Raw Normal View History

Simplify CMake per-source license notices Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.

Use Module for Java
This file provides functions for Java. It is assumed that
:module:`FindJava` has already been loaded. See :module:`FindJava` for
information on how to load Java into your CMake project.
Creating And Installing JARs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: cmake
add_jar(<target_name>
[SOURCES] <source1> [<source2>...] [<resource1>...]
[INCLUDE_JARS <jar1> [<jar2>...]]
[ENTRY_POINT <entry>]
[VERSION <version>]
[OUTPUT_NAME <name>]
[OUTPUT_DIR <dir>]
[GENERATE_NATIVE_HEADERS <target> [DESTINATION <dir>]]
)
This command creates a ``<target_name>.jar``. It compiles the given
``<source>`` files and adds the given ``<resource>`` files to
the jar file. Source files can be java files or listing files
(prefixed by ``@``). 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``.
Optionally, using option ``GENERATE_NATIVE_HEADERS``, native header files can
be generated for methods declared as native. These files provide the
connective glue that allow your Java and C code to interact. An INTERFACE
target will be created for an easy usage of generated files. Sub-option
``DESTINATION`` can be used to specify the output directory for generated
header files.
``GENERATE_NATIVE_HEADERS`` option requires, at least, version 1.8 of the JDK.
The ``add_jar()`` function sets the following target properties on
``<target_name>``:
``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.
``CLASSDIR``
The directory where the class files can be found. For example to use them
with ``javah``.
.. code-block:: cmake
install_jar(<target_name> <destination>)
install_jar(<target_name> DESTINATION <destination> [COMPONENT <component>])
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.
The ``install_jar()`` function sets the ``INSTALL_DESTINATION`` target
property on jars so installed. This property holds the ``<destination>`` as
described above, and is used by ``install_jar_exports()``. You can get this
information with :command:`get_property` and the ``INSTALL_DESTINATION``
property key.
.. code-block:: cmake
install_jni_symlink(<target_name> <destination>)
install_jni_symlink(<target_name> DESTINATION <destination> [COMPONENT <component>])
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.
.. code-block:: cmake
install_jar_exports(TARGETS <jars>...
[NAMESPACE <namespace>]
FILE <filename>
DESTINATION <destination> [COMPONENT <component>])
This command installs a target export file ``<filename>`` for the named jar
targets to the given ``<destination>`` directory. Its function is similar to
that of :command:`install(EXPORTS)`.
.. code-block:: cmake
export_jars(TARGETS <jars>...
[NAMESPACE <namespace>]
FILE <filename>)
This command writes a target export file ``<filename>`` for the named ``<jars>``
targets. Its function is similar to that of :command:`export`.
Examples
""""""""
To add compile flags to the target you can set these flags with the following
variable:
.. code-block:: cmake
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.
.. code-block:: cmake
set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
To use a different output name for the target you can set it with:
.. code-block:: cmake
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:
.. code-block:: cmake
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:
.. code-block:: cmake
add_jar(example ENTRY_POINT com/examples/MyProject/Main)
To define a custom manifest for the jar, you can set it with the ``MANIFEST``
named argument:
.. code-block:: cmake
add_jar(example MANIFEST /path/to/manifest)
To add a version to the target output name you can set it using the ``VERSION``
named argument to ``add_jar()``. The following example 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.
.. code-block:: cmake
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:
.. code-block:: cmake
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:
.. code-block:: cmake
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)
For an optimum usage of option ``GENERATE_NATIVE_HEADERS``, it is recommended to
include module JNI before any call to ``add_jar()``. The produced target for
native headers can then be used to compile C/C++ sources with the
:command:`target_link_libraries` command.
.. code-block:: cmake
find_package(JNI)
add_jar(foo foo.java GENERATE_NATIVE_HEADERS foo-native)
add_library(bar bar.cpp)
target_link_libraries(bar PRIVATE foo-native)
Finding JARs
^^^^^^^^^^^^
.. code-block:: cmake
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 store 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.
Javadoc
^^^^^^^
The ``create_javadoc()`` command can be used to 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.
.. code-block:: cmake
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]
)
For example:
.. code-block:: cmake
create_javadoc(my_example_doc
PACKAGES com.example.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.
.. code-block:: cmake
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]
)
For example:
.. code-block:: cmake
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``.
If you don't set the ``INSTALLPATH``, then by default the documentation will
be installed to :
::
${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
Header Generation
^^^^^^^^^^^^^^^^^
.. code-block:: cmake
create_javah(TARGET <target> | GENERATED_FILES <VAR>
CLASSES <class>...
[CLASSPATH <classpath>...]
[DEPENDS <depend>...]
[OUTPUT_NAME <path>|OUTPUT_DIR <path>]
)
Create C header files from java classes. These files provide the connective glue
that allow your Java and C code to interact.
.. deprecated:: 3.11
.. note::
This command will no longer be supported starting with version 10 of the JDK
due to the `suppression of javah tool <http://openjdk.java.net/jeps/313>`_.
The ``add_jar(GENERATE_NATIVE_HEADERS)`` command should be used instead.
There are two main signatures for ``create_javah()``. The first signature
returns generated files through variable specified by the ``GENERATED_FILES``
option. For example:
.. code-block:: cmake
create_javah(GENERATED_FILES files_headers
CLASSES org.cmake.HelloWorld
CLASSPATH hello.jar
)
The second signature for ``create_javah()`` creates a target which encapsulates
header files generation. E.g.
.. code-block:: cmake
create_javah(TARGET target_headers
CLASSES org.cmake.HelloWorld
CLASSPATH hello.jar
)
Both signatures share same options.
``CLASSES <class>...``
Specifies Java classes used to generate headers.
``CLASSPATH <classpath>...``
Specifies various paths to look up classes. Here .class files, jar files or
targets created by command add_jar can be used.
``DEPENDS <depend>...``
Targets on which the javah target depends.
``OUTPUT_NAME <path>``
Concatenates the resulting header files for all the classes listed by option
``CLASSES`` into ``<path>``. Same behavior as option ``-o`` of javah tool.
``OUTPUT_DIR <path>``
Sets the directory where the header files will be generated. Same behavior
as option ``-d`` of javah tool. If not specified,
:variable:`CMAKE_CURRENT_BINARY_DIR` is used as the output directory.
