Creating And Installing JARs
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. _add_jar:

.. command:: add_jar

  Creates a jar file containing java objects and, optionally, resources:

  .. code-block:: cmake

    add_jar(<target_name>
            [SOURCES] <source1> [<source2>...] [<resource1>...]
            [RESOURCES NAMESPACE <ns1> <resource1>... [NAMESPACE <nsX> <resourceX>...]... ]
            [INCLUDE_JARS <jar1> [<jar2>...]]
            [INCLUDE_MODULES <jar1> [<jar2>...]]
            [ENTRY_POINT <entry>]
            [VERSION <version>]
            [MANIFEST <manifest>]
            [OUTPUT_NAME <name>]
            [OUTPUT_DIR <dir>]
            [GENERATE_NATIVE_HEADERS <target>
                                     [DESTINATION (<dir>|INSTALL <dir> [BUILD <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.

  ``SOURCES``
    Compiles the specified source files and adds the result in the jar file.

    .. versionadded:: 3.4
      Support for response files, prefixed by ``@``.

  ``RESOURCES``
    .. versionadded:: 3.21

    Adds the named ``<resource>`` files to the jar by stripping the source file
    path and placing the file beneath ``<ns>`` within the jar.

    For example::

      RESOURCES NAMESPACE "/com/my/namespace" "a/path/to/resource.txt"

    results in a resource accessible via ``/com/my/namespace/resource.txt``
    within the jar.

    Resources may be added without adjusting the namespace by adding them to
    the list of ``SOURCES`` (original behavior), in this case, resource
    paths must be relative to ``CMAKE_CURRENT_SOURCE_DIR``.  Adding resources
    without using the ``RESOURCES`` parameter in out of source builds will
    almost certainly result in confusion.

    .. note::

      Adding resources via the ``SOURCES`` parameter relies upon a hard-coded
      list of file extensions which are tested to determine whether they
      compile (e.g. File.java). ``SOURCES`` files which match the extensions
      are compiled. Files which do not match are treated as resources. To
      include uncompiled resources matching those file extensions use
      the ``RESOURCES`` parameter.

  ``INCLUDE_JARS``
    The list of 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).

  ``INCLUDE_MODULES``
    .. versionadded:: 4.3

    The list of jars are added to the module path when building the java sources
    and also to the dependencies of the target. ``INCLUDE_MODULES`` also
    accepts other target names created by ``add_jar()``.

  ``ENTRY_POINT``
    Defines an entry point in the jar file.

  ``VERSION``
    Adds a version to the target output name.

    The following example will create a jar file with the name
    ``shibboleet-1.2.0.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)

  ``MANIFEST``
    Defines a custom manifest for the jar.

  ``OUTPUT_NAME``
    Specify a different output name for the target.

  ``OUTPUT_DIR``
    Sets the directory where the jar file will be generated. If not specified,
    :variable:`CMAKE_CURRENT_BINARY_DIR` is used as the output directory.

  ``GENERATE_NATIVE_HEADERS``
    .. versionadded:: 3.11

    Generates native header files 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.

    This option requires, at least, version 1.8 of the JDK.

    For an optimum usage of this option, 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)

    .. versionadded:: 3.20
      ``DESTINATION`` sub-option now supports the possibility to specify
      different output directories for ``BUILD`` and ``INSTALL`` steps. If
      ``BUILD`` directory is not specified, a default directory will be used.

      To export the interface target generated by ``GENERATE_NATIVE_HEADERS``
      option, sub-option ``INSTALL`` of ``DESTINATION`` is required:

      .. code-block:: cmake

        add_jar(foo foo.java GENERATE_NATIVE_HEADERS foo-native
                             DESTINATION INSTALL include)
        install(TARGETS foo-native EXPORT native)
        install(DIRECTORY "$<TARGET_PROPERTY:foo-native,NATIVE_HEADERS_DIRECTORY>/"
                DESTINATION include)
        install(EXPORT native DESTINATION /to/export NAMESPACE foo)

  Some variables can be set to customize the behavior of ``add_jar()`` as well
  as the java compiler:

  ``CMAKE_JAVA_COMPILE_FLAGS``
    Specify additional flags to java compiler.

  ``CMAKE_JAVA_INCLUDE_PATH``
    Specify additional paths to the class path.

  ``CMAKE_JNI_TARGET``
    If the target is a JNI library, sets this boolean variable to ``TRUE`` to
    enable creation of a JNI symbolic link (see also
    :ref:`install_jni_symlink() <install_jni_symlink>`).

  ``CMAKE_JAR_CLASSES_PREFIX``
    If multiple jars should be produced from the same java source filetree,
    to prevent the accumulation of duplicate class files in subsequent jars,
    set/reset ``CMAKE_JAR_CLASSES_PREFIX`` prior to calling the ``add_jar()``:

    .. 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)

  The ``add_jar()`` function sets the following target properties on
  ``<target_name>``:

  ``INSTALL_FILES``
    The files which should be installed.  This is used by
    :ref:`install_jar() <install_jar>`.
  ``JNI_SYMLINK``
    The JNI symlink which should be installed.  This is used by
    :ref:`install_jni_symlink() <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``.
  ``NATIVE_HEADERS_DIRECTORY``
    .. versionadded:: 3.20

    The directory where native headers are generated. Defined when option
    ``GENERATE_NATIVE_HEADERS`` is specified.

.. _install_jar:

.. command:: install_jar

  This command installs the jar file to the given destination:

  .. code-block:: cmake

   install_jar(<target_name> <destination>)
   install_jar(<target_name> DESTINATION <destination> [COMPONENT <component>])

  This command installs the ``<target_name>`` file to the given
  ``<destination>``.  It should be called in the same scope as
  :ref:`add_jar() <add_jar>` or it will fail.

  .. versionadded:: 3.4
    The second signature with ``DESTINATION`` and ``COMPONENT`` options.

  ``DESTINATION``
    Specify the directory on disk to which a file will be installed.

  ``COMPONENT``
    Specify an installation component name with which the install rule is
    associated, such as "runtime" or "development".

  The ``install_jar()`` command sets the following target properties
  on ``<target_name>``:

  ``INSTALL_DESTINATION``
    Holds the ``<destination>`` as described above, and is used by
    :ref:`install_jar_exports() <install_jar_exports>`.

.. _install_jni_symlink:

.. command:: install_jni_symlink

  Installs JNI symlinks for target generated by :ref:`add_jar() <add_jar>`:

  .. 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
  :ref:`add_jar() <add_jar>` or it will fail.

  .. versionadded:: 3.4
    The second signature with ``DESTINATION`` and ``COMPONENT`` options.

  ``DESTINATION``
    Specify the directory on disk to which a file will be installed.

  ``COMPONENT``
    Specify an installation component name with which the install rule is
    associated, such as "runtime" or "development".

  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})

Header Generation
^^^^^^^^^^^^^^^^^

.. _create_javah:

.. command:: create_javah

  .. versionadded:: 3.4

  Generates C header files for java classes:

  .. code-block:: cmake

   create_javah(TARGET <target> | GENERATED_FILES <VAR>
                CLASSES <class>...
                [CLASSPATH <classpath>...]
                [DEPENDS <depend>...]
                [OUTPUT_NAME <path>|OUTPUT_DIR <path>]
                )

  .. deprecated:: 3.11
    This command will no longer be supported starting with version 10 of the JDK
    due to the `suppression of javah tool <https://openjdk.org/jeps/313>`_.
    The :ref:`add_jar(GENERATE_NATIVE_HEADERS) <add_jar>` command should be
    used instead.

  Create C header files from java classes. These files provide the connective
  glue that allow your Java and C code to interact.

  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``
    Specifies Java classes used to generate headers.

  ``CLASSPATH``
    Specifies various paths to look up classes. Here ``.class`` files, jar
    files or targets created by command add_jar can be used.

  ``DEPENDS``
    Targets on which the javah target depends.

  ``OUTPUT_NAME``
    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``
    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.

Exporting JAR Targets
^^^^^^^^^^^^^^^^^^^^^

.. _install_jar_exports:

.. command:: install_jar_exports

  .. versionadded:: 3.7

  Installs a target export file:

  .. 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(EXPORT)`.

  ``TARGETS``
    List of targets created by :ref:`add_jar() <add_jar>` command.

  ``NAMESPACE``
    .. versionadded:: 3.9

    The ``<namespace>`` value will be prepend to the target names as they are
    written to the import file.

  ``FILE``
    Specify name of the export file.


  ``DESTINATION``
    Specify the directory on disk to which a file will be installed.

  ``COMPONENT``
    Specify an installation component name with which the install rule is
    associated, such as "runtime" or "development".

.. _export_jars:

.. command:: export_jars

  .. versionadded:: 3.7

  Writes a target export file:

  .. 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`.

  ``TARGETS``
    List of targets created by :ref:`add_jar() <add_jar>` command.

  ``NAMESPACE``
    .. versionadded:: 3.9

    The ``<namespace>`` value will be prepend to the target names as they are
    written to the import file.

  ``FILE``
    Specify name of the export file.

Finding JARs
^^^^^^^^^^^^

.. _find_jar:

.. command:: find_jar

  Finds the specified jar file:

  .. 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.

  ``NAMES``
    Specify one or more possible names for the jar file.

  ``PATHS``
    Specify directories to search in addition to the default locations.
    The ``ENV`` var sub-option reads paths from a system environment variable.

  ``VERSIONS``
    Specify jar versions.

  ``DOC``
    Specify the documentation string for the ``<VAR>`` cache entry.

Creating Java Documentation
^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. _create_javadoc:

.. command:: create_javadoc

  Creates java documentation based on files and packages:

  .. code-block:: cmake

    create_javadoc(<VAR>
                   (PACKAGES <pkg1> [<pkg2>...] | FILES <file1> [<file2>...])
                   [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)]
                   )

  The ``create_javadoc()`` command can be used to create java documentation.
  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(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(my_example_doc
                   FILES java/A.java java/B.java
                   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. For more details please read the
  javadoc manpage.

  ``PACKAGES``
    Specify java packages.

  ``FILES``
    Specify java source files. If relative paths are specified, they are
    relative to :variable:`CMAKE_CURRENT_SOURCE_DIR`.

  ``SOURCEPATH``
    Specify the directory where to look for packages. By default,
    :variable:`CMAKE_CURRENT_SOURCE_DIR` directory is used.

  ``CLASSPATH``
    Specify where to find user class files. Same behavior as option
    ``-classpath`` of ``javadoc`` tool.

  ``INSTALLPATH``
    Specify where to install the java documentation. If you specified, the
    documentation will be installed to
    ``${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>``.

  ``DOCTITLE``
    Specify the title to place near the top of the overview summary file.
    Same behavior as option ``-doctitle`` of ``javadoc`` tool.

  ``WINDOWTITLE``
    Specify the title to be placed in the HTML ``<title>`` tag. Same behavior
    as option ``-windowtitle`` of ``javadoc`` tool.

  ``AUTHOR``
    When value ``TRUE`` is specified, includes the ``@author`` text in the
    generated docs. Same behavior as option  ``-author`` of ``javadoc`` tool.

  ``USE``
    When value ``TRUE`` is specified, creates class and package usage pages.
    Includes one Use page for each documented class and package. Same behavior
    as option ``-use`` of ``javadoc`` tool.

  ``VERSION``
    When value ``TRUE`` is specified, includes the version text in the
    generated docs. Same behavior as option ``-version`` of ``javadoc`` tool.
