FindJava
--------
Find Java
This module finds if Java is installed and determines where the
include files and libraries are. The caller may set variable ``JAVA_HOME``
to specify a Java installation prefix explicitly.
See also the :module:`FindJNI` module to find Java Native Interface (JNI).
.. versionadded:: 3.10
Added support for Java 9+ version parsing.
Specify one or more of the following components as you call this find module. See example below.
::
Runtime = Java Runtime Environment used to execute Java byte-compiled applications
Development = Development tools (java, javac, javah, jar and javadoc), includes Runtime component
IdlJ = Interface Description Language (IDL) to Java compiler
JarSigner = Signer and verifier tool for Java Archive (JAR) files
This module sets the following result variables:
::
Java_JAVA_EXECUTABLE = the full path to the Java runtime
Java_JAVAC_EXECUTABLE = the full path to the Java compiler
Java_JAVAH_EXECUTABLE = the full path to the Java header generator
Java_JAVADOC_EXECUTABLE = the full path to the Java documentation generator
Java_IDLJ_EXECUTABLE = the full path to the Java idl compiler
Java_JAR_EXECUTABLE = the full path to the Java archiver
Java_JARSIGNER_EXECUTABLE = the full path to the Java jar signer
Java_VERSION_STRING = Version of java found, eg. 1.6.0_12
Java_VERSION_MAJOR = The major version of the package found.
Java_VERSION_MINOR = The minor version of the package found.
Java_VERSION_PATCH = The patch version of the package found.
Java_VERSION_TWEAK = The tweak version of the package found (after '_')
Java_VERSION = This is set to: $major[.$minor[.$patch[.$tweak]]]
.. versionadded:: 3.4
Added the ``Java_IDLJ_EXECUTABLE`` and ``Java_JARSIGNER_EXECUTABLE``
variables.
The minimum required version of Java can be specified using the
:command:`find_package` syntax, e.g.
.. code-block:: cmake
find_package(Java 1.8)
NOTE: ``${Java_VERSION}`` and ``${Java_VERSION_STRING}`` are not guaranteed to
be identical. For example some java version may return:
``Java_VERSION_STRING = 1.8.0_17`` and ``Java_VERSION = 1.8.0.17``
another example is the Java OEM, with: ``Java_VERSION_STRING = 1.8.0-oem``
and ``Java_VERSION = 1.8.0``
For these components the following variables are set:
::
Java_FOUND - TRUE if all components are found.
Java_<component>_FOUND - TRUE if <component> is found.
Example Usages:
::
find_package(Java)
find_package(Java 1.8 REQUIRED)
find_package(Java COMPONENTS Runtime)
find_package(Java COMPONENTS Development)
