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.
